Also, a small number of people with [...]

The HLA DQ2 and DQ8 haplotypes are two genetic variations that have long been known to be associated with an increased risk of celiac disease. Most people who develop celiac disease carry either the DQ2 haplotype or the DQ8 haplotype. A recent study has now identified a genotype which may actually protect an individual from [...]
