VIP

Full Name: Vasoactive Intestinal Peptide

Genomic Location: Chromosome 6:152,747,923-152,759,765

Protein Size: 170 amino acids

Function:

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.

Linked SNP(s):

  • rs9479402 is linked to VIP, it is located approximately 55,000 bases upstream.
  • Population frequencies are approximately 95% for the reference allele (T) and 5% for the alternate allele (C).
  • Studies suggest the T allele is associated with being a morning person.
