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 Likely_pathogenic. Variant got 8 ACMG points.

• PVS1: Loss of function variant, product does not undergo nonsense mediated mRNA decay. Variant is located in the 3'-most 50 bp of the penultimate exon, not predicted to undergo nonsense mediated mRNA decay. Fraction of 0.17 CDS is truncated, and there are 2 pathogenic variants in the truncated region.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 15-60499995-C-T is Pathogenic according to our data. Variant chr15-60499995-C-T is described in ClinVar as [Likely_pathogenic]. Clinvar id is 2501285.Status of the report is criteria_provided_single_submitter, 1 stars.

Variant summary: RORA c.1304G>A (p.Trp435X) results in a premature termination codon, predicted to cause a truncation of the encoded protein or absence of the protein due to nonsense mediated decay, which are commonly known mechanisms for disease. A truncation and a missense change downstream of this position have been reported in affected individuals (HGMD), suggesting a functional importance for the deleted protein region. The variant was absent in 249540 control chromosomes (gnomAD). To our knowledge, no occurrence of c.1304G>A in individuals affected with Intellectual Developmental Disorder with or without Epilepsy or Cerebellar Ataxia and no experimental evidence demonstrating its impact on protein function have been reported. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014. Based on the evidence outlined above, the variant was classified as likely pathogenic. -
