A pilot study of interferon-induced helicase and glutamate decarboxylase gene polymorphism with autoimmune thyroid disease.

Background: Numerous genes are involved in immune system modulation, and their polymorphisms may contribute to developing autoimmune disorders. Genetic variation contributes significantly to disease susceptibility to autoimmune thyroid disease (AITD).

Objectives: This work aims to investigate the role of single-nucleotide polymorphisms (SNPs) of interferon induced with helicase C domain 1 (IFIH1) rs1990760 and glutamate decarboxylase (GAD) rs769404 in AITD development.
