Coeliac disease is an inflammatory disorder of the small intestine with an autoimmune component and strong heritability. Genetic studies have confirmed strong association to HLA and identified 39 nonHLA risk genes, mostly immune-related. Over 50% of the disease-associated single nucleotide polymorphisms are correlated with gene expression. Most of the coeliac disease-associated regions are shared with other immune-related diseases, as well as with metabolic, haematological or neurological traits, or cancer. We review recent progress in the genetics of coeliac disease and describe the pathways these genes are in, the functional consequences of the associated markers on gene expression and the genes shared between coeliac disease and other traits.
