Illumina Laboratory Services, Illumina RCV000298668 SCV000373279 uncertain significance Bardet-Biedl syndrome 1 2018-01-13 criteria provided, single submitter clinical testing This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease.

Labcorp Genetics (formerly Invitae), Labcorp RCV003114476 SCV003785378 uncertain significance Bardet-Biedl syndrome 2022-06-08 criteria provided, single submitter clinical testing This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 465 of the BBS1 protein (p.Arg465His). This variant is present in population databases (rs146072788, gnomAD 0.01%). 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: 305470). 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: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). 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 RCV004742379 SCV005342773 uncertain significance BBS1-related disorder 2024-05-15 no assertion criteria provided clinical testing The BBS1 c.1394G>A variant is predicted to result in the amino acid substitution p.Arg465His. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.010% of alleles in individuals of East Asian descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence.
