Invitae RCV000203410 SCV000641778 pathogenic Methylmalonic aciduria due to methylmalonyl-CoA mutase deficiency 2018-11-09 criteria provided, single submitter clinical testing This sequence change results in a premature translational stop signal in the MUT gene (p.Arg727*). While this is not anticipated to result in nonsense mediated decay, it is expected to delete the last 24 amino acids of the MUT protein. This variant is present in population databases (rs779990936, ExAC 0.01%). This variant has been reported as homozygous or in combination with another MUT variant in multiple individuals affected with methylmalonic acidemia (PMID: 16281286, 17445044, 22727635, 17075691, 26454439, 27489777). ClinVar contains an entry for this variant (Variation ID: 218998). For these reasons, this variant has been classified as Pathogenic.
