Genes affected

VIP (HGNC:12693): (vasoactive intestinal peptide) The protein encoded by this gene belongs to the glucagon family. It stimulates myocardial contractility, causes vasodilation, increases glycogenolysis, lowers arterial blood pressure and relaxes the smooth muscle of trachea, stomach and gall bladder. The protein also acts as an antimicrobial peptide with antibacterial and antifungal activity. Alternative splicing occurs at this locus and two transcript variants encoding distinct isoforms have been identified. [provided by RefSeq, Nov 2014]

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.22330612).

Ambry Genetics

Apr 25, 2023

The c.60C>G (p.F20L) alteration is located in exon 2 (coding exon 1) of the VIP gene. This alteration results from a C to G substitution at nucleotide position 60, causing the phenylalanine (F) at amino acid position 20 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
