GeneDx RCV002473249 SCV002770037 uncertain significance not provided 2022-06-22 criteria provided, single submitter clinical testing In silico analysis supports that this missense variant does not alter protein structure/function; Has not been previously published as pathogenic or benign to our knowledge
Invitae RCV002473249 SCV004381765 uncertain significance not provided 2023-02-03 criteria provided, single submitter clinical testing This sequence change replaces methionine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 182 of the PPP1CB protein (p.Met182Val). This variant is present in population databases (rs768286092, gnomAD 0.007%). This variant has not been reported in the literature in individuals affected with PPP1CB-related conditions. ClinVar contains an entry for this variant (Variation ID: 981575). 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 PPP1CB 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.
