Labcorp Genetics (formerly Invitae), Labcorp RCV001914986 SCV002177285 uncertain significance Short-rib thoracic dysplasia 10 with or without polydactyly; Retinitis pigmentosa 71 2024-02-24 criteria provided, single submitter clinical testing This sequence change replaces glycine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 170 of the IFT172 protein (p.Gly170Val). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with IFT172-related conditions. ClinVar contains an entry for this variant (Variation ID: 1398332). 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 expected to disrupt IFT172 protein function with a positive predictive value of 80%. 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.
