Global estimates of the prevalence of<unk>  range from 1 in 400 to 1 in 10,000 people. Individuals of Northern European descent are most likely to be affected and estimates of the rates of<unk>  in British and Finnish populations range from 30 in 100,000 to 75 in 100,000 people, respectively. The annual incidence rate of<unk>  in these populations range from 0.8 to 2.7 per 100,000. People of all ages may be affected, although the mean age at diagnosis varies between 30–40 years of age. There is a slight male predominance in<unk>  for unknown reasons and it is associated with celiac disease and the haplotypes HLA-DQ2 and, less commonly, HLA-DQ8.
