Description

Variant classified as Uncertain Significance - Favor Benign. The Pro1962Leu vari ant in SCN5A has not been previously reported by our laboratory. It has been ide ntified in 1/2600 control chromosomes (Kapa 2009) and in 3/8386 European America n chromosomes from a broad population by the NHLBI Exome Sequencing Project (htt p://evs.gs.washington.edu/EVS/). Proline (Pro) at position 1962 is not conserved in mammals (maramoset has a Leucine (Leu; this variant) at this position) sugge sting that this variant may be tolerated. Additional computational analyses (bio chemical amino acid properties, AlignGVGD, PolyPhen2, and SIFT) do not provide s trong support for or against an impact to the protein. In summary, the frequency of this variant along with its presence in another primate supports that it may be benign, though additional studies are needed to fully assess its clinical si gnificance.
