RCV001264047 | SCV003929047 | likely pathogenic | Sandhoff disease | 2023-04-12 | criteria provided, single submitter | clinical testing | Variant summary: HEXB c.529C>T (p.Gln177X) 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 247878 control chromosomes. To our knowledge, no occurrence of c.529C>T in individuals affected with Sandhoff Disease and no experimental evidence demonstrating its impact on protein function have been reported. One clinical diagnostic laboratory has submitted clinical-significance assessments for this variant to ClinVar after 2014 and classified the variant as likely pathogenic. Based on the evidence outlined above, the variant was classified as likely pathogenic. |
