| mycobacterium avium subsp. paratuberculosis, genetic susceptibility to crohn's disease, and sardinians: the way ahead. | the present study was performed to determine what proportion of people in sardinia with or without crohn's disease were infected with mycobacterium avium subspecies paratuberculosis and had a preponderance of allelic variants of nod 2, an intracellular protein involved in crohn's disease susceptibility. genetic analysis of the alleles of the nod 2/card 15 gene (ins c 3020, g 908 r, and r 702 w alleles), linked to susceptibility or genetic predisposition to crohn's disease in humans, was carried ... | 2005 | 16207995 |
