Labcorp Genetics (formerly Invitae), Labcorp RCV000803530 SCV000943408 uncertain significance Immunodeficiency 39 2019-07-18 criteria provided, single submitter clinical testing This variant has not been reported in the literature in individuals with IRF7-related disease. This variant is not present in population databases (ExAC no frequency). This sequence change replaces glutamine with arginine at codon 425 of the IRF7 protein (p.Gln425Arg). The glutamine residue is weakly conserved and there is a small physicochemical difference between glutamine and arginine. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The arginine amino acid residue is found in multiple mammalian species, suggesting that this missense change does not adversely affect protein function. These predictions have not been confirmed by published functional studies and their clinical significance is uncertain. 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 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.
