Background: Hashimoto´s thyroiditis (HT) and Graves´ disease (GD) are known co-aggregate in families, but the magnitude and nature of a shared etiology is unknown. The aim of this study was to estimate the shared genetic influence on these diseases. In addition, we sought to examine if the heritability of HT and GD differs between men and women.Methods: We used national health registries to identify cases of HT and GD in a cohort of 110 814 Swe...

Background: Primary adrenal insufficiency (PAI) is sometimes misdiagnosed as autoimmune Addison’s disease (AAD), affecting clinical management and genetic counselling. We tested a polygenic risk score (PRS) for AAD (PRS14AAD) as a tool to reevaluate disease etiology and identify patients misdiagnosed with AAD.Methods: We calculated the PRS14AAD in a cohort of patients diagnosed with AAD but lacking 21-hydroxylase autoantibodies...
