Labcorp Genetics (formerly Invitae), Labcorp RCV001374287 SCV001571097 uncertain significance Bardet-Biedl syndrome 2022-08-12 criteria provided, single submitter clinical testing This sequence change replaces lysine, which is basic and polar, with arginine, which is basic and polar, at codon 39 of the BBS2 protein (p.Lys39Arg). This variant is present in population databases (rs779677560, gnomAD 0.007%). This missense change has been observed in individual(s) with BBS2-related conditions (PMID: 32349990). ClinVar contains an entry for this variant (Variation ID: 1064332). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. 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.
