Genes affected

RBM19 (HGNC:29098): (RNA binding motif protein 19) This gene encodes a nucleolar protein that contains six RNA-binding motifs. The encoded protein may be involved in regulating ribosome biogenesis. Multiple alternatively spliced variants, encoding the same protein, have been identified.[provided by RefSeq, Apr 2009]

The c.2666G>A (p.R889K) alteration is located in exon 23 (coding exon 23) of the RBM19 gene. This alteration results from a G to A substitution at nucleotide position 2666, causing the arginine (R) at amino acid position 889 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
