Labcorp Genetics (formerly Invitae), Labcorp RCV001988508 SCV002272667 uncertain significance Short-rib thoracic dysplasia 10 with or without polydactyly; Retinitis pigmentosa 71 2022-06-13 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 658 of the IFT172 protein (p.Arg658Gln). This variant is present in population databases (rs376890875, gnomAD 0.004%). This variant has not been reported in the literature in individuals affected with IFT172-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. 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.
