PreventionGenetics, part of Exact Sciences

The SDCCAG8 c.916G>A variant is predicted to result in the amino acid substitution p.Glu306Lys. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.062% of alleles in individuals of South Asian descent in gnomAD. Although we suspect that this variant may be benign, at this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -

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. -

This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 306 of the SDCCAG8 protein (p.Glu306Lys). This variant is present in population databases (rs777002036, gnomAD 0.06%). This variant has not been reported in the literature in individuals affected with SDCCAG8-related conditions. ClinVar contains an entry for this variant (Variation ID: 474960). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt SDCCAG8 protein function. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
