Genes affected

RBM5 (HGNC:9902): (RNA binding motif protein 5) This gene is a candidate tumor suppressor gene which encodes a nuclear RNA binding protein that is a component of the spliceosome A complex. The encoded protein plays a role in the induction of cell cycle arrest and apoptosis through pre-mRNA splicing of multiple target genes including the tumor suppressor protein p53. This gene is located within the tumor suppressor region 3p21.3, and may play a role in the inhibition of tumor transformation and progression of several malignancies including lung cancer.

The c.1277C>T (p.P426L) alteration is located in exon 15 (coding exon 14) of the RBM5 gene. This alteration results from a C to T substitution at nucleotide position 1277, causing the proline (P) at amino acid position 426 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
