Labcorp Genetics (formerly Invitae), Labcorp RCV002647234 SCV003513397 uncertain significance Cone-rod dystrophy 13; Leber congenital amaurosis 6 2022-07-20 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 814 of the RPGRIP1 protein (p.Arg814Gln). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with RPGRIP1-related conditions. 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 glutamine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect 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.
Ambry Genetics RCV002624060 SCV003591703 uncertain significance Inborn genetic diseases 2021-11-30 criteria provided, single submitter clinical testing The c.2441G>A (p.R814Q) alteration is located in exon 16 (coding exon 16) of the RPGRIP1 gene. This alteration results from a G to A substitution at nucleotide position 2441, causing the arginine (R) at amino acid position 814 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
