Etiopathogenetic Mechanisms in Diverticular Disease of the Colon

Cell Mol Gastroenterol Hepatol. 2020;9(1):15-32. doi: 10.1016/j.jcmgh.2019.07.007. Epub 2019 Jul 25.


This article reviews epidemiological evidence of heritability and putative mechanisms in diverticular disease, with greatest attention to 3 recent studies of genetic associations with diverticular disease based on genome-wide or whole-genome sequencing studies in large patient cohorts. We provide an analysis of the biological plausibility of the significant associations with gene variants reported and highlight the relevance of ANO1, CPI-17 (aka PPP1R14A), COLQ6, COL6A1, CALCB or CALCA, COL6A1, ARHGAP15, and S100A10 to colonic neuromuscular function and tissue properties that may result in altered compliance and predispose to the development of diverticular disease. Such studies also identify candidate genes for future studies.

Keywords: Diverticular Hemorrhage; Diverticulitis; Diverticulum.
