RCV000041375 | SCV000065068 | likely pathogenic | Primary dilated cardiomyopathy | 2012-08-13 | criteria provided, single submitter | clinical testing | The Ala288Gly variant in LMNA has not been reported in the literature nor in 2 l arge and broad populations (European and African American) screened by the NHLBI Exome Sequencing Project (http://evs.gs.washington.edu/EVS/). This low frequen cy supports a pathogenic role. Our laboratory has detected this variant in one i ndividual with DCM + atrial fibrillation as well as one affected family member w ith atrial fibrillation. The constellation of features present in this family is consistent with a laminopathy. Computational analyses (biochemical amino acid p roperties, conservation, AlignGVGD, PolyPhen2, and SIFT) suggest that the Ala288 Gly variant may impact the protein, though this information is not predictive en ough to determine pathogenicity. In summary, this variant is likely to be pathog enic, though additional studies are required to establish this with certainty. |
