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

Our verdict: Likely_pathogenic. The variant received 6 ACMG points.

• PM1: In a DNA_binding_region Nuclear receptor (size 65) in uniprot entity RORA_HUMAN there are 5 pathogenic changes around while only 0 benign (100%) in NM_134261.3
• PM2: Very rare variant in population databases, with high coverage
• PP3: Splicing predictors support a deleterious effect. Scorers claiming Pathogenic: dbscSNV1_ADA, dbscSNV1_RF. No scorers claiming Uncertain. Scorers claiming Benign: max_spliceai.
• PP5: Variant 15-60531767-T-C is Pathogenic according to our data. Variant chr15-60531767-T-C is described in ClinVar as [Pathogenic]. Clinvar id is 549844.Status of the report is no_assertion_criteria_provided, 0 stars.
