Integrated Genetics/Laboratory Corporation of America RCV000780492 SCV000917793 pathogenic Methylmalonic acidemia 2018-08-27 criteria provided, single submitter clinical testing Variant summary: MUT c.2194_2197delinsTGGAA (p.Ala732TrpfsX6) results in a premature termination codon, predicted to cause a truncation of the encoded protein or absence of the protein due to nonsense mediated decay, which are commonly known mechanisms for disease. The variant was absent in 246164 control chromosomes (gnomAD). c.2194_2197delinsTGGAA has been reported in the literature in individuals affected with Methylmalonic Acidemia (Cavicchi_2005, Forny_2016, Worgan_2006). These data indicate that the variant is likely to be associated with disease. At least one publication reports experimental evidence evaluating an impact on protein function. The most pronounced variant effect results in <10% of normal activity. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014. Based on the evidence outlined above, the variant was classified as pathogenic.
