Labcorp Genetics (formerly Invitae), Labcorp RCV001377155 SCV001574407 pathogenic Bardet-Biedl syndrome 2024-01-31 criteria provided, single submitter clinical testing This sequence change replaces glycine, which is neutral and non-polar, with cysteine, which is neutral and slightly polar, at codon 81 of the BBS2 protein (p.Gly81Cys). This variant is present in population databases (rs750506474, gnomAD 0.002%). This missense change has been observed in individual(s) with Bardet-Biedl syndrome (PMID: 21344540, 27353947). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 557198). 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 expected to disrupt BBS2 protein function with a positive predictive value of 80%. For these reasons, this variant has been classified as Pathogenic.
