Invitae RCV000472989 SCV000553780 uncertain significance Bardet-Biedl syndrome 2022-04-09 criteria provided, single submitter clinical testing This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 146 of the BBS1 protein (p.Arg146Gln). This variant is present in population databases (rs759253107, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with BBS1-related conditions. ClinVar contains an entry for this variant (Variation ID: 412286). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The glutamine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect 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.
Ambry Genetics RCV002525625 SCV003730962 likely benign Inborn genetic diseases 2021-12-06 criteria provided, single submitter clinical testing This alteration is classified as likely benign based on a combination of the following: population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity.
