[JOURNAL ARTICLE] Clin Vaccine Immunol 2007 Nov 7.
TNFalpha -308G/A and LTalpha +249A/G were investigated in 228 type-1 diabetes (T1DM) patients and 240 controls. Only LTalpha +249G allele and +249G/+249G genotype frequencies were higher among patients, and no LD was found between TNFalpha/LTalpha alleles and susceptible/protective DRB1-DQB1 haplotypes TNFalpha/LTalpha T1DM susceptible (-308G/+249G) and protective (-308G/+249A) haplotypes were identified.
