Allelic variants in the PHTF1-PTPN22, C12orf30 and CD226 regions as candidate susceptibility factors for the type 1 diabetes in the Estonian population.
BACKGROUND
Type 1 diabetes is a multifactorial disease with a strong genetic component. The aim of the study was to assess the impact of single nucleotide polymorphisms (SNPs) in several genes as susceptible markers in the risk of type 1 diabetes in the Estonian population.


METHODS
The rs6679677 (1p13), rs17696736 (12q24) and rs763361 (18q22) were genotyped in a total of 230 controls and 154 type 1 diabetes patients of Estonian origin.


RESULTS
The rs6679677 A (OR = 2.13, 95%CI = 1.48-3.08, p = 0.00001), rs17696736 G (OR = 1.53, 95%CI = 1.14-2.04, p = 0.0046) and rs763361 T (OR = 1.48, 95%CI = 1.11-1.98, p = 0.0084) alleles were associated with risk of type 1 diabetes.


CONCLUSIONS
The current study supports the rs6679677 (PHTF1-PTPN22), rs17696736 (C12orf30) and rs763361 (CD226) SNPs as susceptibility factors for type 1 diabetes outside the major histocompatibility region (MHC) region. The full study had 80% or above to detect an odds ratio of 1.8 under the assumption of an additive model at type 1 error rate, alpha = 0.05.
