Genes affected

RBM23 (HGNC:20155): (RNA binding motif protein 23) This gene encodes a member of the U2AF-like family of RNA binding proteins. This protein interacts with some steroid nuclear receptors, localizes to the promoter of a steroid- responsive gene, and increases transcription of steroid-responsive transcriptional reporters in a hormone-dependent manner. It is also implicated in the steroid receptor-dependent regulation of alternative splicing. Multiple transcript variants encoding different isoforms have been found for this gene.

Sep 16, 2021

The c.661C>G (p.P221A) alteration is located in exon 8 (coding exon 7) of the RBM23 gene. This alteration results from a C to G substitution at nucleotide position 661, causing the proline (P) at amino acid position 221 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
