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

Verdict is Benign. Variant got -10 ACMG points.

• BP6: Variant 5-93583271-GTC-G is Benign according to our data. Variant chr5-93583271-GTC-G is described in ClinVar as [Likely_benign]. Clinvar id is 1186466.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00603 (870/144392) while in subpopulation AFR AF= 0.0143 (560/39260). AF 95% confidence interval is 0.0133. There are 5 homozygotes in gnomad4. There are 440 alleles in male gnomad4 subpopulation. Median coverage is 25. This position pass quality control queck.
• BS2: High AC in GnomAd4 at 870 AD gene.
