An autoimmune disorder that affects the thyroid gland, called autoimmune hypothyroidism (AIHT), is the most common autoimmune disease, yet it remains largely understudied. New research from scientists at Broad Institute, University of Helsinki, and other institutions has now found more than 400 genetic markers linked to the disorder, far more than previous studies. Nearly 50 of these pinpoint protein-coding changes in genes involved in immunity and thyroid function.
