Variant summary

Our verdict is Pathogenic. The variant received 11 ACMG points: 11P and 0B. PM1 PM2 PP2 PP3_Strong PP5_Moderate

The NM_005654.6(NR2F1):​c.344G>C​(p.Arg115Pro) variant causes a missense change. 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. R115L) has been classified as Uncertain significance.

Genes affected

NR2F1 (HGNC:7975): (nuclear receptor subfamily 2 group F member 1) The protein encoded by this gene is a nuclear hormone receptor and transcriptional regulator. The encoded protein acts as a homodimer and binds to 5'-AGGTCA-3' repeats. Defects in this gene are a cause of Bosch-Boonstra optic atrophy syndrome (BBOAS). [provided by RefSeq, Apr 2014]

NR2F1-AS1 (HGNC:48622): (NR2F1 antisense RNA 1)

ACMG classification

Our verdict: Pathogenic. The variant received 11 ACMG points.

• PM1: In a hotspot region, there are 10 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 3 uncertain in NM_005654.6
• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in the NR2F1 gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 51 curated pathogenic missense variants (we use a threshold of 10). The gene has 7 curated benign missense variants. Gene score misZ: 4.1652 (above the threshold of 3.09). Trascript score misZ: 4.6855 (above the threshold of 3.09). GenCC associations: The gene is linked to Bosch-Boonstra-Schaaf optic atrophy syndrome.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.976
• PP5: Variant 5-93585367-G-C is Pathogenic according to our data. Variant chr5-93585367-G-C is described in ClinVar as [Likely_pathogenic]. Clinvar id is 126493.Status of the report is criteria_provided_single_submitter, 1 stars.
