Labcorp Genetics (formerly Invitae), Labcorp RCV001295478 SCV001484401 uncertain significance Senior-Loken syndrome 7; Bardet-Biedl syndrome 16 2022-09-19 criteria provided, single submitter clinical testing This sequence change replaces arginine, which is basic and polar, with glycine, which is neutral and non-polar, at codon 95 of the SDCCAG8 protein (p.Arg95Gly). This variant is present in population databases (rs377564587, gnomAD 0.008%). 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: 999475). 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.

PreventionGenetics, part of Exact Sciences RCV004531077 SCV004114954 uncertain significance SDCCAG8-related disorder 2023-06-07 criteria provided, single submitter clinical testing The SDCCAG8 c.283A>G variant is predicted to result in the amino acid substitution p.Arg95Gly. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.0080% of alleles in individuals of African descent in gnomAD (http://gnomad.broadinstitute.org/variant/1-243434342-A-G). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence.
