Description

The Asp928Ala variant in MYH7 has been reported in 1 individual with HCM as well as 3 asymptomatic relatives (Michels 2009) and was not identified in large popu lation studies (http://evs.gs.washington.edu/EVS/). Another variant at this pos ition (Asp928Asn) has been reported in individuals with HCM (Erdman 2003, Gimeno 2009, Perrot 2005), suggesting that a change at this position may not be tolera ted. Computational analyses (biochemical amino acid properties, conservation, A lignGVGD, PolyPhen2, and SIFT) suggest that the Asp928Ala variant may impact the protein, though this information is not predictive enough to determine pathogen icity. Additional information is needed to fully assess the clinical significan ce of the Asp928Ala variant.
