About 40% of the population express the CeD-associated risk genes, but only 1%-2% of the worldwide population has CeD. This, along with the rising prevalence of CeD suggests other cofactors in disease pathogenesis. The gut microbiome has been implicated in CeD based on epidemiology studies and clinical associations.
