Invitae RCV001202289 SCV001373397 uncertain significance Jeune thoracic dystrophy 2019-10-01 criteria provided, single submitter clinical testing Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site, but this prediction has not been confirmed by published transcriptional studies. 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. 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, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant has not been reported in the literature in individuals with IFT80-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces glutamine with arginine at codon 319 of the IFT80 protein (p.Gln319Arg). The glutamine residue is highly conserved and there is a small physicochemical difference between glutamine and arginine.
