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

Classification made for transcript

Verdict is Likely_pathogenic. Variant got 6 ACMG points.

PVS1

Splicing +-2 bp (donor or acceptor) variant, product NOT destroyed by NMD, known LOF gene, truncates exone, which is 0.2509804 fraction of the gene. Cryptic splice site detected, with MaxEntScore 7.1, offset of -3, new splice context is: cttttcctcatgttccttAGctg. Cryptic site results in inframe change. If cryptic site found is not functional and variant results in exon loss, it results in inframe change.

PM2

Very rare variant in population databases, with high coverage;

The c.337A>T (p.S113C) alteration is located in exon 5 (coding exon 4) of the VIP gene. This alteration results from a A to T substitution at nucleotide position 337, causing the serine (S) at amino acid position 113 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
