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. -

Illumina Laboratory Services, Illumina

Jan 13, 2018

This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease. -

Ambry Genetics

Feb 13, 2018

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
