Invitae RCV001203896 SCV001375077 uncertain significance Jeune thoracic dystrophy 2023-10-03 criteria provided, single submitter clinical testing This sequence change replaces serine, which is neutral and polar, with glycine, which is neutral and non-polar, at codon 974 of the DYNC2H1 protein (p.Ser974Gly). 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 missense change has been observed in individual(s) with clinical features of short-rib polydactyly syndrome (Invitae). ClinVar contains an entry for this variant (Variation ID: 935328). 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 DYNC2H1 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.
