Genes affected

NR2E3 (HGNC:7974): (nuclear receptor subfamily 2 group E member 3) This protein is part of a large family of nuclear receptor transcription factors involved in signaling pathways. Nuclear receptors have been shown to regulate pathways involved in embryonic development, as well as in maintenance of proper cell function in adults. Members of this family are characterized by discrete domains that function in DNA and ligand binding. This gene encodes a retinal nuclear receptor that is a ligand-dependent transcription factor. Defects in this gene are a cause of enhanced S cone syndrome. Alternatively spliced transcript variants encoding different isoforms have been identified. [provided by RefSeq, Jul 2008]

This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 309 of the NR2E3 protein (p.Arg309Gln). This variant is present in population databases (rs761628767, gnomAD 0.003%). This missense change has been observed in individual(s) with autosomal recessive enhanced S-cone syndrome (PMID: 32679203). ClinVar contains an entry for this variant (Variation ID: 1355514). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt NR2E3 protein function with a negative predictive value of 80%. This variant disrupts the p.Arg309 amino acid residue in NR2E3. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 10655056, 15459973, 19718767; internal data). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. 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. -
