Invitae RCV001203309 SCV001374466 uncertain significance Senior-Loken syndrome 7; Bardet-Biedl syndrome 16 2023-05-01 criteria provided, single submitter clinical testing 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. 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. ClinVar contains an entry for this variant (Variation ID: 934835). This variant has not been reported in the literature in individuals affected with SDCCAG8-related conditions. This variant is present in population databases (rs750977682, gnomAD 0.009%). This sequence change replaces lysine, which is basic and polar, with arginine, which is basic and polar, at codon 78 of the SDCCAG8 protein (p.Lys78Arg).
Preventiongenetics, part of Exact Sciences RCV003425989 SCV004107376 uncertain significance SDCCAG8-related condition 2023-09-11 criteria provided, single submitter clinical testing The SDCCAG8 c.233A>G variant is predicted to result in the amino acid substitution p.Lys78Arg. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.011% of alleles in individuals of Latino descent in gnomAD (http://gnomad.broadinstitute.org/variant/1-243434292-A-G). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence.
