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]

ACMG classification

Verdict is Pathogenic. Variant got 13 ACMG points.

• PM1: In a zinc_finger_region NR C4-type (size 20) in uniprot entity NR2E3_HUMAN there are 19 pathogenic changes around while only 0 benign (100%) in ENST00000617575.5
• PM4: Nonframeshift variant in NON repetitive region in ENST00000617575.5.
• PP3: No computational evidence supports a deleterious effect, but strongly conserved according to phyloP
• PP5: Variant 15-71811552-CCTGCAACGG-C is Pathogenic according to our data. Variant chr15-71811552-CCTGCAACGG-C is described in ClinVar as [Likely_pathogenic]. Clinvar id is 551852.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr15-71811552-CCTGCAACGG-C is described in Lovd as [Pathogenic].

For these reasons, this variant has been classified as Pathogenic. Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. ClinVar contains an entry for this variant (Variation ID: 551852). This variant has been observed in individual(s) with autosomal recessive enhanced S-cone syndrome/Goldmann-Favre syndrome (PMID: 12963616, 19273793, 19898638, 21364904, 28541266). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. This variant is present in population databases (no rsID available, gnomAD 0.008%). This variant, c.194_202del, results in the deletion of 3 amino acid(s) of the NR2E3 protein (p.Asn65_Cys67del), but otherwise preserves the integrity of the reading frame. -
