Repeated Screening Can Be Restricted to At-Genetic-Risk Birth Cohorts.

Celiac disease is associated with tissue transglutaminase autoantibodies (tTGA) in individuals carrying the HLA risk-haplotypes DQA105:01-DQB102:01 (DQ2) and/or DQA103:01-DQB103:02 (DQ8). The aim was to identify celiac disease in a HLA genotyped birth-cohort prospectively screened for celiac disease.
