Women's Health and Genetics/Laboratory Corporation of America, LabCorp RCV004766942 SCV005381176 pathogenic Oculocutaneous albinism 2024-08-13 criteria provided, single submitter clinical testing Variant summary: TYR c.272G>C (p.Cys91Ser) 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 was absent in 251134 control chromosomes. c.272G>C has been reported in the literature in individuals affected with Oculocutaneous Albinism (Miyamura_2005, Chaki_2006). These data indicate that the variant may be associated with disease. At least one publication reports experimental evidence evaluating an impact on protein function and showed that this variant leads to complete loss of enzyme activity (Chaki_2011). No submitters have cited clinical-significance assessments for this variant to ClinVar. Other variants affecting this codon (p.C91F, p.C91R, p.C91Y) have been reported in HGMD and ClinVar databases. Based on the evidence outlined above, the variant was classified as pathogenic.
