Genes affected

VIPR1 (HGNC:12694): (vasoactive intestinal peptide receptor 1) 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. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2011]

The c.195G>T (p.K65N) alteration is located in exon 3 (coding exon 3) of the VIPR1 gene. This alteration results from a G to T substitution at nucleotide position 195, causing the lysine (K) at amino acid position 65 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
