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: Likely_benign. The variant received -4 ACMG points.

• BS1: Variant frequency is greater than expected in population sas. GnomAd4 allele frequency = 0.000489 (71/145068) while in subpopulation SAS AF = 0.0018 (8/4448). AF 95% confidence interval is 0.000894. There are 0 homozygotes in GnomAd4. There are 30 alleles in the male GnomAd4 subpopulation. Median coverage is 25. This position passed quality control check.
