Association of different alleles of immune response modifier genes IL1B (+3953A1/A2), IL1RN (VNTR), IL4 (3'-UTR G/C), IL4RA (I50V), IL12B (1188A/C), and VDR (F/f and B/b) with celiac disease (CD) and its clinical forms was investigated in a family cohort of CD patients from the Tomsk region (N = 139, including 49 probands, i.e., affected children). The control group comprised 129 healthy Russians from Tomsk. A case-control study did not associate any of the polymorphic markers with CD. In a family-based study, the 3'-UTR G/C polymorphism of IL4 was associated with CD (P = 0.024), its atypical form (P = 0.001), and its complications such as osteopenia (P = 0.039) and autoimmune thyroiditis (P = 0.042). IL4RA and VDR polymorphisms I50V and F/f were associated with the typical form of CD (P = 0.001 and P = 0.009, respectively). In general, associations with CD phenotypes were shown primarily for polymorphisms of the genes involved in Th2 immunity.
