Genes affected

VIPR2 (HGNC:12695): (vasoactive intestinal peptide receptor 2) This gene encodes a receptor for vasoactive intestinal peptide, a small neuropeptide. Vasoactive intestinal peptide is involved in smooth muscle relaxation, exocrine and endocrine secretion, and water and ion flux in lung and intestinal epithelia. Its actions are effected through integral membrane receptors associated with a guanine nucleotide binding protein which activates adenylate cyclase. [provided by RefSeq, Aug 2011]

The c.1277G>T (p.R426L) alteration is located in exon 13 (coding exon 13) of the VIPR2 gene. This alteration results from a G to T substitution at nucleotide position 1277, causing the arginine (R) 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. -
