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.

The c.755C>G (p.A252G) alteration is located in exon 9 (coding exon 8) of the RBM23 gene. This alteration results from a C to G substitution at nucleotide position 755, causing the alanine (A) at amino acid position 252 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
