Variant summary

Our verdict is Pathogenic. The variant received 24 ACMG points: 24P and 0B. PS1_Very_Strong PM1 PM2 PP3_Strong PP5_Very_Strong

The NM_014249.4(NR2E3):​c.166G>C​(p.Gly56Arg) 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 nucleotide change resulting in the same amino acid substitution has been previously reported as Likely pathogenic in ClinVar. Synonymous variant affecting the same amino acid position (i.e. G56G) has been classified as Likely benign.

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

Our verdict: Pathogenic. The variant received 24 ACMG points.

• PS1: Transcript NM_014249.4 (NR2E3) is affected with MISSENSE_VARIANT having same AA change as one Pathogenic present in ClinVar.
• PM1: In a hotspot region, there are 3 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 15 uncertain in NM_014249.4
• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.983
• PP5: Variant 15-71811530-G-C is Pathogenic according to our data. Variant chr15-71811530-G-C is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 1076269.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
