Genes affected

RBPMS2 (HGNC:19098): (RNA binding protein, mRNA processing factor 2) The protein encoded by this gene is a member of the RNA recognition motif (RRM)-containing protein family and is involved in the development and dedifferentiation of digestive smooth muscle cells. The encoded protein functions as a homodimer and indirectly inhibits the bone morphogenetic protein pathway. [provided by RefSeq, Aug 2016]

The c.376G>A (p.V126M) alteration is located in exon 5 (coding exon 5) of the RBPMS2 gene. This alteration results from a G to A substitution at nucleotide position 376, causing the valine (V) at amino acid position 126 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
