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]

Collection Method: clinical testing

The c.154C>T (p.R52W) alteration is located in exon 2 (coding exon 2) of the RBPMS2 gene. This alteration results from a C to T substitution at nucleotide position 154, causing the arginine (R) at amino acid position 52 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
