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: Benign. The variant received -8 ACMG points.

• BS1: Variant frequency is greater than expected in population eas. GnomAd4 allele frequency = 0.00312 (452/145066) while in subpopulation EAS AF = 0.0413 (201/4870). AF 95% confidence interval is 0.0366. There are 4 homozygotes in GnomAd4. There are 239 alleles in the male GnomAd4 subpopulation. Median coverage is 25. This position passed quality control check.
• BS2: High Homozygotes in GnomAd4 at 4 AD,AR gene
