Genes affected

RPGRIP1 (HGNC:13436): (RPGR interacting protein 1) This gene encodes a photoreceptor protein that interacts with retinitis pigmentosa GTPase regulator protein and is a key component of cone and rod photoreceptor cells. Mutations in this gene lead to autosomal recessive congenital blindness. [provided by RefSeq, Oct 2008]

This variant has not been reported in the literature in individuals affected with RPGRIP1-related conditions. 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. ClinVar contains an entry for this variant (Variation ID: 534364). This variant is present in population databases (no rsID available, gnomAD 0.01%). This sequence change replaces leucine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 1256 of the RPGRIP1 protein (p.Leu1256Val). -
