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]

ACMG classification

Verdict is Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.52).
• BP6: Variant 5-93593851-C-T is Benign according to our data. Variant chr5-93593851-C-T is described in ClinVar as [Benign]. Clinvar id is 385015.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr5-93593851-C-T is described in Lovd as [Likely_benign].
• BS1: Variant frequency is greater than expected in population sas. gnomad4 allele frequency = 0.0000854 (13/152278) while in subpopulation SAS AF= 0.00124 (6/4826). AF 95% confidence interval is 0.000541. There are 0 homozygotes in gnomad4. There are 7 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High AC in GnomAd at 14 AD gene.
