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 -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.42).
• BP6: Variant 5-93583263-A-G is Benign according to our data. Variant chr5-93583263-A-G is described in ClinVar as [Likely_benign]. Clinvar id is 1703910.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00339 (470/138654) while in subpopulation AFR AF= 0.0112 (414/37026). AF 95% confidence interval is 0.0103. There are 3 homozygotes in gnomad4. There are 219 alleles in male gnomad4 subpopulation. Median coverage is 30. This position pass quality control queck.
• BS2: High AC in GnomAd at 469 AD gene.
