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]

The NR2E3 c.364C>T variant is predicted to result in the amino acid substitution p.Arg122Cys. This variant has been reported in the homozygous state in two siblings with retinitis pigmentosa from a consanguineous family (Family RP670, Bocquet et al. 2013. PubMed ID: 24339724). This variant has also been reported in the homozygous and compound heterozygous states in additional unrelated individuals with retinal dystrophies (Murro et al. 2018. PubMed ID: 30324420; Patient K6189, Table S6, Oishi et al. 2014. PubMed ID: 25324289; Table S2, Zampaglione et al. 2020. PubMed ID: 32037395). This variant is reported in 0.0081% of alleles in individuals of East Asian descent in gnomAD. Given the evidence, we interpret this variant as likely pathogenic. -

This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 122 of the NR2E3 protein (p.Arg122Cys). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This missense change has been observed in individual(s) with clinical features of autosomal recessive NR2E3-related conditions (PMID: 24339724, 30324420, 32037395; Invitae). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 143147). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt NR2E3 protein function with a positive predictive value of 80%. For these reasons, this variant has been classified as Pathogenic. -
