RCV000183326 | SCV000235758 | uncertain significance | not provided | 2014-03-31 | criteria provided, single submitter | clinical testing | p.His6Tyr (CAC>TAC): c.16 C>T in exon 1 of the CRYAB gene (NM_001885.1). A variant of unknown significance has been identified in the CRYAB gene. The H6Y variant has not been published as a mutation, nor has it been reported as a benign polymorphism to our knowledge. The H6Y variant was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. The H6Y variant is a non-conservative amino acid substitution, which is likely to impact secondary protein structure as these residues differ in polarity, charge, size and/or other properties. This substitution occurs at a position that is conserved in mammals. In silico algorithms are not consistent in their predictions but at least two concur that H6Y is benign to the protein structure/function. Therefore, based on the currently available information, it is unclear whether this variant is a pathogenic mutation or a rare benign variant. The variant is found in CARDIOMYOPATHY panel(s). |
