A study on the IFIH1 gene polymorphism in children with type 1 diabetes in Tianjin area / 中华内分泌代谢杂志

ABSTRACT

The blood samples of 102 type 1 diabetic children aged under 15 years and 127 normal children were collected and their genomic DNAs were extracted. The single nucleotide polymorphisms rs1990760 and rs35744605 of interferon induced with helicase C domain 1(IFIH1)gene were detected. The results showed that the allele of IFIH1 rs35744605 in diabetes group and control group was the wild type G allele. The frequency of IFIH1 rs1990760 A allele in diabetes group was higher than that in control group(22. 1％ vs 13. 0％ ,P=0. 015), suggesting that IFIH1 rs1990760 A allele is associated with type 1 diabetes in Tianjin area.
