The association of Haptoglobin polymorphism with Crohn's disease in Israel

We found a borderline significant decrease of the Haptoglobin 1-1 phenotype in Israeli Crohn's disease patients compared to healthy controls. Our findings may support the importance of inflammation in Crohn's disease pathogenesis and the protective function of Haptoglobin 1-1 in the susceptibility for Crohn's disease.
