RCV001363860 | SCV001559989 | uncertain significance | Retinitis pigmentosa 12; Leber congenital amaurosis 8 | 2021-08-30 | criteria provided, single submitter | clinical testing | This sequence change replaces aspartic acid with asparagine at codon 1084 of the CRB1 protein (p.Asp1084Asn). The aspartic acid residue is highly conserved and there is a small physicochemical difference between aspartic acid and asparagine. This variant is present in population databases (rs769059111, ExAC 0.03%). This variant has not been reported in the literature in individuals affected with CRB1-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 asparagine 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. |
