Myoadenylate deaminase deficiency (MMDD) is an autosomal recessive condition that can manifest as exercise-induced muscle pain, occasionally associated with rhabdomyolysis and/or increased serum creatine kinase, or even infantile hypotonia. However, the finding of homozygous mutations among asymptomatic individuals have suggested to some (e.g., Verzijl et al., 1998) that AMPD1 deficiency may be a harmless entity (summary by Castro-Gago et al., 2011). Genetta et al. (2001) stated that AMPD1 deficiency is the most prevalent genetic disease in humans, the number of people heterozygous approaching 10% of Caucasians and individuals of African descent (Sabina et al., 1989). A small percentage of homozygous-deficient individuals, approximately 1.8% of the population, display symptoms of chronic fatigue and lost productivity as well as a predisposition to stress-related ailments, including heart disease and stroke, according to Genetta et al. (2001).

Xeroderma pigmentosum (XP) is characterized by: Sun sensitivity (severe sunburn with blistering, persistent erythema on minimal sun exposure in ~60% of affected individuals), with marked freckle-like pigmentation of the face before age two years in most affected individuals; Sunlight-induced ocular involvement (photophobia, keratitis, atrophy of the skin of the lids); Greatly increased risk of sunlight-induced cutaneous neoplasms (basal cell carcinoma, squamous cell carcinoma, melanoma). Approximately 25% of affected individuals have neurologic manifestations (acquired microcephaly, diminished or absent deep tendon stretch reflexes, progressive sensorineural hearing loss, and progressive cognitive impairment). The most common causes of death are skin cancer, neurologic degeneration, and internal cancer. The median age at death in persons with XP with neurodegeneration (29 years) was found to be younger than that in persons with XP without neurodegeneration (37 years).

Clozapine is one of the most effective antipsychotics available in the treatment of schizophrenia and the only antipsychotic found to be effective in treatment-resistant schizophrenia. Clozapine is also used to reduce the risk of recurrent suicidal behavior in patients with schizophrenia or schizoaffective disorder. Compared to typical antipsychotics, clozapine is far less likely to cause movement disorders, known as extrapyramidal side effects, which include dystonia, akathisia, parkinsonism, and tardive dyskinesia. However, there are significant risks associated with clozapine therapy that limits its use to only the most severely ill patients who have not responded adequately to standard drug therapy. Most notably, because of the risk of clozapine-induced agranulocytosis, clozapine treatment requires monitoring of white blood counts and absolute neutrophil counts, and in the US, the FDA requires that patients receiving clozapine be enrolled in a computer-based registry. Clozapine is metabolized in the liver by the cytochrome P450 (CYP) system of enzymes. CYP1A2 is the main CYP isoform in clozapine metabolism and CYP1A2 activity is an important determinant of clozapine dose. Other CYP enzymes involved in clozapine metabolism include CYP2D6 and CYP3A4. Approximately 6-10% of Caucasians have reduced activity of CYP2D6 ("poor metabolizers"). These individuals may develop higher than expected plasma concentrations of clozapine with usual doses. The FDA-approved drug label for clozapine states that a dose reduction may be necessary in patients who are CYP2D6 poor metabolizers.

Low clinical importance, Uncertain pathogenic — This is a common variant was first reported as a polymorphism. It has since had mixed associations with cancer: Storey et al. conclude a 7x *increased* risk of HPV cancer for homozygotes vs hets, but Jones et al. find a 1.98x *decreased* risk for colorectal cancer. This variant may have significant impact on particular cancers, but it is unclear what effect it has on the overall burden of cancer.

Insufficiently evaluated pharmacogenetic — This gene is involved in response to oxidative stress, and the 113H variant is associated with lower enzyme activity, apparently through disruption of protein stability rather than enzymatic function of the protein itself. Several studies have attempted to link this variant to cancer, lung disease, and other associations, but it is unclear which of these are results reproducible and validated.

Clozapine is one of the most effective antipsychotics available in the treatment of schizophrenia and the only antipsychotic found to be effective in treatment-resistant schizophrenia. Clozapine is also used to reduce the risk of recurrent suicidal behavior in patients with schizophrenia or schizoaffective disorder. Compared to typical antipsychotics, clozapine is far less likely to cause movement disorders, known as extrapyramidal side effects, which include dystonia, akathisia, parkinsonism, and tardive dyskinesia. However, there are significant risks associated with clozapine therapy that limits its use to only the most severely ill patients who have not responded adequately to standard drug therapy. Most notably, because of the risk of clozapine-induced agranulocytosis, clozapine treatment requires monitoring of white blood counts and absolute neutrophil counts, and in the US, the FDA requires that patients receiving clozapine be enrolled in a computer-based registry. Clozapine is metabolized in the liver by the cytochrome P450 (CYP) system of enzymes. CYP1A2 is the main CYP isoform in clozapine metabolism and CYP1A2 activity is an important determinant of clozapine dose. Other CYP enzymes involved in clozapine metabolism include CYP2D6 and CYP3A4. Approximately 6-10% of Caucasians have reduced activity of CYP2D6 ("poor metabolizers"). These individuals may develop higher than expected plasma concentrations of clozapine with usual doses. The FDA-approved drug label for clozapine states that a dose reduction may be necessary in patients who are CYP2D6 poor metabolizers.

Clozapine is one of the most effective antipsychotics available in the treatment of schizophrenia and the only antipsychotic found to be effective in treatment-resistant schizophrenia. Clozapine is also used to reduce the risk of recurrent suicidal behavior in patients with schizophrenia or schizoaffective disorder. Compared to typical antipsychotics, clozapine is far less likely to cause movement disorders, known as extrapyramidal side effects, which include dystonia, akathisia, parkinsonism, and tardive dyskinesia. However, there are significant risks associated with clozapine therapy that limits its use to only the most severely ill patients who have not responded adequately to standard drug therapy. Most notably, because of the risk of clozapine-induced agranulocytosis, clozapine treatment requires monitoring of white blood counts and absolute neutrophil counts, and in the US, the FDA requires that patients receiving clozapine be enrolled in a computer-based registry. Clozapine is metabolized in the liver by the cytochrome P450 (CYP) system of enzymes. CYP1A2 is the main CYP isoform in clozapine metabolism and CYP1A2 activity is an important determinant of clozapine dose. Other CYP enzymes involved in clozapine metabolism include CYP2D6 and CYP3A4. Approximately 6-10% of Caucasians have reduced activity of CYP2D6 ("poor metabolizers"). These individuals may develop higher than expected plasma concentrations of clozapine with usual doses. The FDA-approved drug label for clozapine states that a dose reduction may be necessary in patients who are CYP2D6 poor metabolizers.

Lung cancer is the leading cause of cancer deaths in the U.S. and worldwide. The 2 major forms of lung cancer are nonsmall cell lung cancer and small cell lung cancer (see 182280), which account for 85% and 15% of all lung cancers, respectively. Nonsmall cell lung cancer can be divided into 3 major histologic subtypes: squamous cell carcinoma, adenocarcinoma, and large cell lung cancer. Cigarette smoking causes all types of lung cancer, but it is most strongly linked with small cell lung cancer and squamous cell carcinoma. Adenocarcinoma is the most common type in patients who have never smoked. Nonsmall cell lung cancer is often diagnosed at an advanced stage and has a poor prognosis (summary by Herbst et al., 2008).

Orotic aciduria is a rare autosomal recessive disorder characterized by megaloblastic anemia and orotic acid crystalluria that is frequently associated with some degree of physical and mental retardation. These features respond to appropriate pyrimidine replacement therapy, and most cases appear to have a good prognosis. A minority of cases have additional features, particularly congenital malformations and immune deficiencies, which may adversely affect this prognosis (summary by Webster et al., 2001). Bailey (2009) stated that only 2 cases of orotic aciduria without megaloblastic anemia (OAWA) had been reported.

Low clinical importance, Likely pathogenic — This common variant (HapMap allele frequency of 31.3%) in a protein involved in folate (B9) and cobalamin (B12) metabolism and is often reported as "MTRR I22M" (an alternative transcript position). Mothers homozygous for this variant are associated with having around a increased chance of a child with Down syndrome (risk of 0.4%, average risk in population is 0.25%). Notably, age plays a far larger role in the rate of Down syndrome (risk is 4.5% for a mother 45-years-of-age), and it is unknown how this variant may combine with the effect of age. There are conflicting reports associating this variant with incidence of neural tube defects, possibly when combined with MTHFR A222V.

Arrhythmogenic right ventricular cardiomyopathy (ARVC) – previously referred to as arrhythmogenic right ventricular dysplasia (ARVD) – is characterized by progressive fibrofatty replacement of the myocardium that predisposes to ventricular tachycardia and sudden death in young individuals and athletes. It primarily affects the right ventricle, and it may also involve the left ventricle. The presentation of disease is highly variable even within families, and some affected individuals may not meet established clinical criteria. The mean age at diagnosis is 31 years (±13; range: 4-64 years).

Xeroderma pigmentosum (XP) is characterized by: Sun sensitivity (severe sunburn with blistering, persistent erythema on minimal sun exposure in ~60% of affected individuals), with marked freckle-like pigmentation of the face before age two years in most affected individuals; Sunlight-induced ocular involvement (photophobia, keratitis, atrophy of the skin of the lids); Greatly increased risk of sunlight-induced cutaneous neoplasms (basal cell carcinoma, squamous cell carcinoma, melanoma). Approximately 25% of affected individuals have neurologic manifestations (acquired microcephaly, diminished or absent deep tendon stretch reflexes, progressive sensorineural hearing loss, and progressive cognitive impairment). The most common causes of death are skin cancer, neurologic degeneration, and internal cancer. The median age at death in persons with XP with neurodegeneration (29 years) was found to be younger than that in persons with XP without neurodegeneration (37 years).

Highly active antiretroviral therapy (HAART) has reduced mortality associated with acquired immunodeficiency syndrome (AIDS; see 609423) by at least 70%. Efavirenz is a non-nucleoside reverse transcriptase inhibitor that is frequently prescribed with 2 nucleoside reverse transcriptase inhibitors as initial therapy for human immunodeficiency virus (HIV) infection. However, during the first weeks of therapy, up to half of patients who receive efavirenz experience CNS side effects, including dizziness, insomnia, impaired concentration, somnolence, and abnormal dreams. Severe depression, aggressive behavior, and paranoid or manic reactions may also occur, and such side effects may reflect varying efavirenz plasma concentrations. Plasma clearance of efavirenz appears slower in African Americans than in European Americans, and studies have suggested earlier virologic failure on efavirenz for both African Americans and Hispanics compared with European Americans. Efavirenz is metabolized primarily by hepatic CYP2B6, with some involvement of CYP3A (CYP3A4; 124010) (summary by Haas et al., 2004).

Autism, the prototypic pervasive developmental disorder (PDD), is usually apparent by 3 years of age. It is characterized by a triad of limited or absent verbal communication, a lack of reciprocal social interaction or responsiveness, and restricted, stereotypic, and ritualized patterns of interests and behavior (Bailey et al., 1996; Risch et al., 1999). 'Autism spectrum disorder,' sometimes referred to as ASD, is a broader phenotype encompassing the less severe disorders Asperger syndrome (see ASPG1; 608638) and pervasive developmental disorder, not otherwise specified (PDD-NOS). 'Broad autism phenotype' includes individuals with some symptoms of autism, but who do not meet the full criteria for autism or other disorders. Mental retardation coexists in approximately two-thirds of individuals with ASD, except for Asperger syndrome, in which mental retardation is conspicuously absent (Jones et al., 2008). Genetic studies in autism often include family members with these less stringent diagnoses (Schellenberg et al., 2006). Levy et al. (2009) provided a general review of autism and autism spectrum disorder, including epidemiology, characteristics of the disorder, diagnosis, neurobiologic hypotheses for the etiology, genetics, and treatment options. Genetic Heterogeneity of Autism Autism is considered to be a complex multifactorial disorder involving many genes. Accordingly, several loci have been identified, some or all of which may contribute to the phenotype. Included in this entry is AUTS1, which has been mapped to chromosome 7q22. Other susceptibility loci include AUTS3 (608049), which maps to chromosome 13q14; AUTS4 (608636), which maps to chromosome 15q11; AUTS6 (609378), which maps to chromosome 17q11; AUTS7 (610676), which maps to chromosome 17q21; AUTS8 (607373), which maps to chromosome 3q25-q27; AUTS9 (611015), which maps to chromosome 7q31; AUTS10 (611016), which maps to chromosome 7q36; AUTS11 (610836), which maps to chromosome 1q41; AUTS12 (610838), which maps to chromosome 21p13-q11; AUTS13 (610908), which maps to chromosome 12q14; AUTS14A (611913), which has been found in patients with a deletion of a region of 16p11.2; AUTS14B (614671), which has been found in patients with a duplication of a region of 16p11.2; AUTS15 (612100), associated with mutation in the CNTNAP2 gene (604569) on chromosome 7q35-q36; AUTS16 (613410), associated with mutation in the SLC9A9 gene (608396) on chromosome 3q24; AUTS17 (613436), associated with mutation in the SHANK2 gene (603290) on chromosome 11q13; AUTS18 (615032), associated with mutation in the CHD8 gene (610528) on chromosome 14q11; and AUTS19, associated with mutation in the EIF4E gene (133440) on chromosome 4q23. (NOTE: the symbol 'AUTS2' has been used to refer to a gene on chromosome 7q11 (KIAA0442; 607270) and therefore is not used as a part of this autism locus series.) There are several X-linked forms of autism susceptibility: AUTSX1 (300425), associated with mutations in the NLGN3 gene (300336); AUTSX2 (300495), associated with mutations in NLGN4 (300427); AUTSX3 (300496), associated with mutations in MECP2 (300005); AUTSX4 (300830), associated with variation in the region on chromosome Xp22.11 containing the PTCHD1 gene (300828); AUTSX5 (300847), associated with mutations in the RPL10 gene (312173); and AUTSX6 (300872), associated with mutation in the TMLHE gene (300777). A locus on chromosome 2q (606053) associated with a phenotype including intellectual disability and speech deficits was formerly designated AUTS5. Folstein and Rosen-Sheidley (2001) reviewed the genetics of autism.

5-fluorouracil is a chemotherapeutic agent, and a member of the fluoropyrimidine group of substances. It is mainly used to treat solid tumors, such as colorectal, breast and aerodigestive cancers. Dihydropyrimidine dehydrogenase (DPD, encoded by the DPYD gene) is the rate-limiting enzyme for fluoropyrimidine metabolism and is therefore responsible for the detoxification of these types of drugs. Patients who are homozygous for variants in DPYD that lead to a non-functional protein, such as *2A or *13, have a high risk of severe or fatal drug toxicities and may benefit from receiving an alternative chemotherapeutic drug. Patients heterozygous for these variants also have an increased risk for drug toxicities, and reduced dosing is recommended for these individuals. Guidelines regarding the use of pharmacogenomic tests in dosing for 5-fluorouracil have been published in Clinical Pharmacology and Therapeutics by the Clinical Pharmacogenetics Implementation Consortium (CPIC) and are available on the PharmGKB website (http://www.pharmgkb.org/drug/PA128406956).

Hirschsprung disease (HSCR), or congenital intestinal aganglionosis, is a birth defect characterized by complete absence of neuronal ganglion cells from a portion of the intestinal tract. The aganglionic segment includes the distal rectum and a variable length of contiguous proximal intestine. In 80% of individuals, aganglionosis is restricted to the rectosigmoid colon (short-segment disease); in 15%-20%, aganglionosis extends proximal to the sigmoid colon (long-segment disease); in about 5%, aganglionosis affects the entire large intestine (total colonic aganglionosis). Rarely, the aganglionosis extends into the small bowel or even more proximally to encompass the entire bowel (total intestinal aganglionosis). HSCR is considered a neurocristopathy, a disorder of cells and tissues derived from the neural crest, and may occur as an isolated finding or as part of a multisystem disorder. Affected infants frequently present in the first two months of life with symptoms of impaired intestinal motility such as failure to pass meconium within the first 48 hours of life, constipation, emesis, abdominal pain or distention, and occasionally diarrhea. However, because the initial diagnosis of HSCR may be delayed until late childhood or adulthood, HSCR should be considered in anyone with lifelong severe constipation. Individuals with HSCR are at risk for enterocolitis and/or potentially lethal intestinal perforation.

The hereditary hyperbilirubinemias (Wolkoff et al., 1983) include (1) those resulting in predominantly unconjugated hyperbilirubinemia: Gilbert or Arias syndrome, Crigler-Najjar syndrome type I (218800), and Crigler-Najjar syndrome type II (606785); and (2) those resulting in predominantly conjugated hyperbilirubinemia: Dubin-Johnson syndrome (237500), Rotor syndrome (237450), and several forms of intrahepatic cholestasis (147480, 211600, 214950, 243300). Detailed studies show that patients with Gilbert syndrome have reduced activity of bilirubin glucuronosyltransferase (Bosma et al., 1995, Koiwai et al., 1995).

Irinotecan (brand name Camptosar) is a topoisomerase I inhibitor widely used in the treatment of cancer. It is most frequently used in combination with other drugs to treat advanced or metastatic colorectal cancer. However, irinotecan therapy is associated with a high incidence of toxicity, including severe neutropenia and diarrhea. Irinotecan is converted in the body to an active metabolite known as SN-38, which is then inactivated and detoxified by a UDP-glucuronosyltransferase (UGT) enzyme encoded by the UGT1A1 gene. The UGT enzymes are responsible for glucuronidation, a process that transforms lipophilic metabolites into water-soluble metabolites that can be excreted from the body. The risk of irinotecan toxicity increases with genetic variants associated with reduced UGT enzyme activity, such as UGT1A1*28. The presence of this variant results in reduced excretion of irinotecan metabolites, which leads to increased active irinotecan metabolites in the blood. Approximately 10% of North Americans carry 2 copies of the UGT1A1*28 allele (homozygous, UGT1A1 *28/*28), and are more likely to develop neutropenia following irinotecan therapy. The FDA-approved drug label for irinotecan states that “when administered as a single-agent, a reduction in the starting dose by at least one level of irinotecan hydrochloride injection should be considered for patients known to be homozygous for the UGT1A1*28 allele. However, the precise dose reduction in this patient population is not known and subsequent dose modifications should be considered based on individual patient tolerance to treatment”. The Dutch Pharmacogenetics Working Group (DPWG) of the Royal Dutch Association for the Advancement of Pharmacy (KNMP) recommends starting with 70% of the standard dose for homozygous carriers of the UGT1A1*28 allele. If the patient tolerates this initial dose, the dose can be increased guided by the neutrophil count. They state that no action is needed for heterozygous carriers of the UGT1A1*28 allele (e.g., UGT1A1 *1/*28). In addition, the French National Network of Pharmacogenetics (RNPGx) has proposed a decision tree for guiding irinotecan prescribing based on the UGT1A1 genotype and irinotecan dose.

This individual has one copy of the genetic mutation, and because it's autosomal recessive, they are likely a carrier rather than manifesting the condition. Interpretation of carrier status should be backed by thorough research.

Clopidogrel is a thienopyridine antiplatelet agent that prevents platelet activation and aggregation by irreversibly inhibiting the P2Y12 ADP receptors. As a pro-drug, clopidogrel requires hepatic biotransformation to form an active metabolite. This conversion is composed of two sequential oxidative steps, which involve cytochrome P450-2C19 (CYP2C19) and other enzymes. Genetic variants in CYP2C19 such as CYP2C19*2, along with other genetic and non-genetic factors, are known to influence variability in clopidogrel response. Specific CYP2C19 variants impair formation of the active clopidogrel metabolite, which results in reduced platelet inhibition. Among clopidogrel-treated patients with acute coronary syndromes (ACSs) undergoing percutaneous coronary intervention (PCI), patients with specific variants in the CYP2C19 gene might be at increased risk for serious adverse cardiovascular events and may benefit from an alternative antiplatelet therapy as compared to patients without these variants. Guidelines regarding the use of pharmacogenomic tests in dosing for clopidogrel have been published in Clinical Pharmacology and Therapeutics by the Clinical Pharmacogenetics Implementation Consortium (CPIC) and are available on the PharmGKB website.

Insufficiently evaluated pharmacogenetic — This variant defines the CYP2C19*2 haplotype and is associated with diminished response of clopidogrel (plavix). Compared to individuals who do not have this variant, carriers of this variant are more likely to have a major adverse cardiovascular event despite treatment with clopidogrel.

Type 2 diabetes is a disorder characterized by abnormally high blood sugar levels. In this form of diabetes, the body stops using and making insulin properly. Insulin is a hormone produced in the pancreas that helps regulate blood sugar levels. Specifically, insulin controls how much glucose (a type of sugar) is passed from the blood into cells, where it is used as an energy source. When blood sugar levels are high (such as after a meal), the pancreas releases insulin to move the excess glucose into cells, which reduces the amount of glucose in the blood.Most people who develop type 2 diabetes first have insulin resistance, a condition in which the body's cells use insulin less efficiently than normal. As insulin resistance develops, more and more insulin is needed to keep blood sugar levels in the normal range. To keep up with the increasing need, insulin-producing cells in the pancreas (called beta cells) make larger amounts of insulin. Over time, the beta cells become less able to respond to blood sugar changes, leading to an insulin shortage that prevents the body from reducing blood sugar levels effectively. Most people have some insulin resistance as they age, but inadequate exercise and excessive weight gain make it worse, greatly increasing the likelihood of developing type 2 diabetes.Type 2 diabetes can occur at any age, but it most commonly begins in middle age or later. Signs and symptoms develop slowly over years. They include frequent urination (polyuria), excessive thirst (polydipsia), fatigue, blurred vision, tingling or loss of feeling in the hands and feet (diabetic neuropathy), sores that do not heal well, and weight loss. If blood sugar levels are not controlled through medication or diet, type 2 diabetes can cause long-lasting (chronic) health problems including heart disease and stroke; nerve damage; and damage to the kidneys, eyes, and other parts of the body.

Warfarin is an oral anti-coagulant used world-wide to treat and prevent thrombotic disorders. While it is highly effective, it has a very narrow therapeutic index making it difficult to dose correctly. Genetic variants in both cytochrome P450-2C9 (CYP2C9) and vitamin K-epoxide reductase complex (VKORC1) enzymes, along with non-genetic factors, are known to affect warfarin dose variability. Patients with specific variants in the gene CYP2C9 (the primary warfarin-metabolizing enzyme), such as CYP2C9*2 and CYP2C9*3, may require a lower dose of warfarin as compared to patients without these variants. Patients with a specific variant in VKORC1 (the target enzyme of warfarin), known as -1639G>A or rs9923231, may require a lower warfarin dose as compared to patients who do not have this variant. The combination of CYP2C9 and VKORC1 genetic variants, along with clinical factors, can put some patients at risk for adverse events such as bleeding. Guidelines regarding the use of pharmacogenomic tests in dosing for warfarin have been published in Clinical Pharmacology and Therapeutics by the Clinical Pharmacogenetics Implementation Consortium (CPIC) and are available on the PharmGKB website.

Cystic fibrosis (CF) is a multisystem disease affecting epithelia of the respiratory tract, exocrine pancreas, intestine, hepatobiliary system, and exocrine sweat glands. Morbidities include progressive obstructive lung disease with bronchiectasis, frequent hospitalizations for pulmonary disease, pancreatic insufficiency and malnutrition, recurrent sinusitis and bronchitis, and male infertility. Pulmonary disease is the major cause of morbidity and mortality in CF. Meconium ileus occurs at birth in 15%-20% of newborns with CF. More than 95% of males with CF are infertile. Congenital absence of the vas deferens (CAVD) is generally identified during evaluation of infertility or as an incidental finding at the time of a surgical procedure. Hypoplasia or aplasia of the vas deferens and seminal vesicles may occur either bilaterally or unilaterally. Testicular development and function and spermatogenesis are usually normal.

The term 'not provided' is registered in MedGen to support identification of submissions to ClinVar for which no condition was named when assessing the variant. 'not provided' differs from 'not specified', which is used when a variant is asserted to be benign, likely benign, or of uncertain significance for conditions that have not been specified.

This individual has one copy of the genetic mutation, and depending on the condition, this mutation can act as either autosomal dominant or recessive. Thus, they might manifest one condition while being a carrier for another. However, it's important to conduct thorough research before drawing definitive conclusions.
