RCV000158427 | SCV000208362 | uncertain significance | not provided | 2011-07-31 | criteria provided, single submitter | clinical testing | This variant is denoted Ala429Glu (aka A429E) at the protein level and c.1286 C>A at the cDNA level. The Ala429Glu variant in the MYBPC3 gene has not been reported previously as a disease causing mutation nor as a benign polymorphism, to our knowledge. Ala429Glu results in a non conservative amino acid substitution of a non polar Alanine with a negatively charged Glutamic acid at a residue that is conserved across species. In addition, the Ala429Glu variant was not detected in up to 600 alleles from control individuals of Caucasian and African American ancestry, indicating it is not a common benign variant in these populations. However, data from ethnically matched controls is not available, therefore we cannot evaluate if Ala429Glu may be a population specific benign variant. In summary, with the clinical and molecular information available at this time, we cannot equivocally determine whether the Ala429Glu variant is a disease causing mutation or a rare benign variant. The variant is found in HCM panel(s). |
