Labcorp Genetics (formerly Invitae), Labcorp RCV000823774 SCV000964644 uncertain significance Cohen syndrome 2022-10-24 criteria provided, single submitter clinical testing This sequence change replaces alanine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 2171 of the VPS13B protein (p.Ala2171Val). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This variant has not been reported in the literature in individuals affected with VPS13B-related conditions. ClinVar contains an entry for this variant (Variation ID: 665480). 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 not expected to disrupt VPS13B protein function. 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.
PreventionGenetics, part of Exact Sciences RCV003392628 SCV004120529 uncertain significance VPS13B-related disorder 2023-11-01 no assertion criteria provided clinical testing The VPS13B c.6437C>T variant is predicted to result in the amino acid substitution p.Ala2146Val. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.0065% of alleles in individuals of European (Non-Finnish) descent in gnomAD (http://gnomad.broadinstitute.org/variant/8-100712143-C-T). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence.
