Our verdict is Likely pathogenic. Variant got 6 ACMG points: 6P and 0B. PM2PP3_Strong
The NM_004624.4(VIPR1):c.260C>G(p.Pro87Arg) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★).
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]
Review Status: criteria provided, single submitter
Collection Method: clinical testing
The c.260C>G (p.P87R) alteration is located in exon 3 (coding exon 3) of the VIPR1 gene. This alteration results from a C to G substitution at nucleotide position 260, causing the proline (P) at amino acid position 87 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
