Genes affected

VMP1 (HGNC:29559): (vacuole membrane protein 1) This gene encodes a transmembrane protein that plays a key regulatory role in the process of autophagy. The ectopic overexpression of the encoded protein in cultured cells triggers autophagy even under nutrient-rich conditions. This gene is overexpressed in pancreatitis affected acinar cells where the encoded protein mediates sequestration and degradation of potentially deleterious activated zymogen granules in a process termed, zymophagy.

The c.485A>G (p.Y162C) alteration is located in exon 6 (coding exon 5) of the VMP1 gene. This alteration results from a A to G substitution at nucleotide position 485, causing the tyrosine (Y) at amino acid position 162 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
