Abstract

Autoimmune thyroid disease is the most common autoimmune disease and is highly heritable1. Here, by using a genome-wide association study of 30,234 cases and 725,172 controls from Iceland and the UK Biobank, we find 99 sequence variants at 93 loci, of which 84 variants are previously unreported2–7. A low-frequency (1.36%) intronic variant in FLT3(rs76428106-C) has the largest effect on risk of autoimmune thyroid disease (odds ratio (OR) = 1.46, P= 2.37 × 10−24). rs76428106-C is also associated with systemic lupus erythematosus (OR = 1.90, P= 6.46 × 10−4), rheumatoid factor and/or anti-CCP-positive rheumatoid arthritis (OR = 1.41, P= 4.31 × 10−4) and coeliac disease (OR = 1.62, P= 1.20 × 10−4). FLT3encodes fms-related tyrosine kinase 3, a receptor that regulates haematopoietic progenitor and dendritic cells. RNA sequencing revealed that rs76428106-C generates a cryptic splice site, which introduces a stop codon in 30% of transcripts that are predicted to encode a truncated protein, which lacks its tyrosine kinase domains. Each copy of rs76428106-C doubles the plasma levels of the FTL3 ligand. Activating somatic mutations in FLT3are associated with acute myeloid leukaemia8with a poor prognosis and rs76428106-C also predisposes individuals to acute myeloid leukaemia (OR = 1.90, P= 5.40 × 10−3). Thus, a predicted loss-of-function germline mutation in FLT3causes a reduction in full-length FLT3, with a compensatory increase in the levels of its ligand and an increased disease risk, similar to that of a gain-of-function mutation.
