Women's Health and Genetics/Laboratory Corporation of America, LabCorp RCV002223077 SCV002500755 uncertain significance not specified 2024-06-12 criteria provided, single submitter clinical testing Variant summary: ATP6V0A2 c.1214C>T (p.Pro405Leu) results in a non-conservative amino acid change in the encoded protein sequence. Five of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 4e-06 in 251424 control chromosomes. c.1214C>T has been reported in the literature in a homozygous individual affected with Cutis Laxa - ATP6V0A2 Related (Hucthagowder_2009, Van Damme_2017). These data indicate that the variant may be associated with disease. At least one publication reports experimental evidence evaluating an impact on protein function. The most pronounced variant effect results in protein instability (half-life approximately 56% of wild-type protein), and expedited degradation in both proteasomal and lysosomal pathways and defective Golgi trafficking as detected by immunofluorescence (Esmail_2018). The following publications have been ascertained in the context of this evaluation (PMID: 29311258, 19321599, 28065471). ClinVar contains an entry for this variant (Variation ID: 1677219). Based on the evidence outlined above, the variant was classified as VUS-possibly pathogenic.
