Labcorp Genetics (formerly Invitae), Labcorp RCV001878088 SCV002162200 uncertain significance Short-rib thoracic dysplasia 10 with or without polydactyly; Retinitis pigmentosa 71 2022-09-27 criteria provided, single submitter clinical testing This sequence change replaces threonine, which is neutral and polar, with alanine, which is neutral and non-polar, at codon 679 of the IFT172 protein (p.Thr679Ala). This variant is present in population databases (rs746240262, gnomAD 0.003%). 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: 1388906). 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 IFT172 protein function. 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.
