Variant summary

Our verdict is Pathogenic. Variant got 10 ACMG points: 10P and 0B. PM1 PM2 PM5 PP3_Moderate PP5_Moderate

The NM_014249.4(NR2E3):​c.926G>T​(p.Arg309Leu) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R309G) has been classified as Likely pathogenic.

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 10 ACMG points.

• PM1: In a domain NR LBD (size 241) in uniprot entity NR2E3_HUMAN there are 34 pathogenic changes around while only 2 benign (94%) in NM_014249.4
• PM2: Very rare variant in population databases, with high coverage
• PM5: Other missense variant is known to change same aminoacid residue: Variant chrnull-null-null-null is described in UniProt as null.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.914
• PP5: Variant 15-71813567-G-T is Pathogenic according to our data. Variant chr15-71813567-G-T is described in ClinVar as [Likely_pathogenic]. Clinvar id is 191062.Status of the report is criteria_provided_single_submitter, 1 stars. Variant chr15-71813567-G-T is described in Lovd as [Likely_pathogenic].
