Abstract
Aims/hypothesis
We set out to validate a recently reported type 1 diabetes association from the IFIH1 gene variation in an independent cohort from a population of mixed European descent.
Methods
We genotyped five single-nucleotide polymorphisms in the IFIH1 locus, i.e. rs2111485, rs1990760, rs3747517, rs17783344 and rs984971589, in 589 type 1 diabetes nuclear family trios (1,767 individuals).
Results
This study independently replicated the reported genetic association using a family-based approach.
Conclusions/interpretation
The reported type 1 diabetes association is from a linkage disequilibrium region including three candidate genes, i.e. FAP, IFIH1 and GCA. Further variant discovery and fine mapping could help clarify a novel type 1 diabetes mechanism.
