Integrated Genetics/Laboratory Corporation of America RCV001175549 SCV001339173 pathogenic Gaucher disease 2020-03-01 criteria provided, single submitter clinical testing Variant summary: GBA c.1603C>T (p.Arg535Cys) also widely reported as p.Arg496Cys, 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 1.2e-05 in 172274 control chromosomes. c.1603C>T has been well reported in the literature in multiple individuals from diverse ethnicities affected with Gaucher Disease (example, Kawame_1992, Karaca_2012, Ankleshwaria_2014 and Feng_2018). These data indicate that the variant is very likely to be associated with disease. No experimental evidence demonstrating an impact on protein function was ascertained. Although at-least one publication reported its identification in a enzymatically and clinically diagnosed Gaucher disease homozygous individual with no primary data provided (Kawame_1992). One researcher has submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation and classified the variant as pathogenic. This submitter cites an overlapping publication utilized in the context of this evaluation. Based on the evidence outlined above, the variant was classified as pathogenic.
