Functional variants in SUMO4, TAB2, and NFkappaB and the risk of type 1 diabetes

Genes Immun. 2005 May;6(3):231-5. doi: 10.1038/sj.gene.6364174.


Several functional genetic variants that can potentially modulate the activity of NFkappaB have been recently described. As reduced NFkappaB activity has been implicated in risk for autoimmune diabetes in the NOD mouse, these variants were tested for allelic association with type 1 diabetes (T1D) in a family based study. Alleles at markers in the TAB2/SUMO4 locus on chromosome 6q had been previously reported to be associated with T1D in two separate studies, but these studies disagreed on the identity of the risk allele. The current study failed to confirm either of these results. No significant evidence of association with T1D was obtained for three SNP markers in the TAB2/SUMO4 region. An additional functional variant in the promoter of the NFKB1 gene that has been shown to directly affect the expression of NFkappaB was also tested.
