Genes affected

RORB (HGNC:10259): (RAR related orphan receptor B) The protein encoded by this gene is a member of the NR1 subfamily of nuclear hormone receptors. It is a DNA-binding protein that can bind as a monomer or as a homodimer to hormone response elements upstream of several genes to enhance the expression of those genes. The encoded protein has been shown to interact with NM23-2, a nucleoside diphosphate kinase involved in organogenesis and differentiation, and to help regulate the expression of some genes involved in circadian rhythm.

RORB-AS1 (HGNC:49803): (RORB antisense RNA 1)

ACMG classification

Our verdict: Benign. The variant received -20 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.68).
• BP6: Variant 9-74498003-C-T is Benign according to our data. Variant chr9-74498003-C-T is described in ClinVar as [Benign]. Clinvar id is 1610805.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BS1: Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.0104 (1583/152188) while in subpopulation AFR AF = 0.0364 (1510/41526). AF 95% confidence interval is 0.0348. There are 21 homozygotes in GnomAd4. There are 727 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
• BS2: High AC in GnomAd4 at 1583 AD gene.
