Genes affected

RORA (HGNC:10258): (RAR related orphan receptor A) The protein encoded by this gene is a member of the NR1 subfamily of nuclear hormone receptors. It 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, as well as with NM23-1, the product of a tumor metastasis suppressor candidate gene. Also, it has been shown to aid in the transcriptional regulation of some genes involved in circadian rhythm. Four transcript variants encoding different isoforms have been described for this gene.

RORA-AS1 (HGNC:51410): (RORA antisense RNA 1)

ACMG classification

Verdict is Pathogenic. Variant got 12 ACMG points.

• PVS1: Loss of function variant, product does not undergo nonsense mediated mRNA decay. Variant is located in the 3'-most exon, not predicted to undergo nonsense mediated mRNA decay. Fraction of 0.0471 CDS is truncated, and there are 1 pathogenic variants in the truncated region.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 15-60497529-G-A is Pathogenic according to our data. Variant chr15-60497529-G-A is described in ClinVar as [Pathogenic]. Clinvar id is 559568.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr15-60497529-G-A is described in Lovd as [Pathogenic].
