NOD2/CARD15 mutation analysis and genotype-phenotype correlation in Jewish pediatric patients compared with adults with Crohn's disease.

OBJECTIVES: The allelic variants in the NOD2/CARD15 gene G908R, R702W, and 1007fs are strongly and independently associated with susceptibility to Crohn's disease (CD). Our aim was to compare the NOD2/CARD15 genotype and the genotype-phenotype correlation in Jewish pediatric patients with CD (
