Genes affected

GPR179 (HGNC:31371): (G protein-coupled receptor 179) This gene encodes a member of the glutamate receptor subfamily of G protein-coupled receptors. The encoded protein has an EGF-like calcium binding domain and a seven transmembrane domain in the N-terminal region of the protein. Mutations in this gene are associated with congenital stationary night blindness type 1E. [provided by RefSeq, Apr 2012]

This variant has not been reported in the literature in individuals affected with GPR179-related conditions. This variant is present in population databases (rs759290545, ExAC 0.01%). This sequence change replaces phenylalanine with serine at codon 2349 of the GPR179 protein (p.Phe2349Ser). The phenylalanine residue is weakly conserved and there is a large physicochemical difference between phenylalanine and serine. 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 serine 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. -
