Invitae RCV001237556 SCV001410320 uncertain significance Bardet-Biedl syndrome 2022-08-09 criteria provided, single submitter clinical testing This sequence change replaces asparagine, which is neutral and polar, with serine, which is neutral and polar, at codon 137 of the BBS9 protein (p.Asn137Ser). This variant is present in population databases (rs752108930, gnomAD 0.003%). This variant has not been reported in the literature in individuals affected with BBS9-related conditions. ClinVar contains an entry for this variant (Variation ID: 963519). 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: "Benign"; Align-GVGD: "Class C45"). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a 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.
PreventionGenetics, part of Exact Sciences RCV003405432 SCV004114067 uncertain significance BBS9-related condition 2023-06-16 criteria provided, single submitter clinical testing The BBS9 c.410A>G variant is predicted to result in the amino acid substitution p.Asn137Ser. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.0029% of alleles in individuals of Latino descent in gnomAD (http://gnomad.broadinstitute.org/variant/7-33217171-A-G). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence.
