Pluriglandular autoimmune syndrome (APS) can affect multiple endocrine glands and is associated with other autoimmune diseases. APS type 1 presents with hypoparathyroidism, mucocutaneous candidiasis and Addison's disease. It is caused by AutoImmune Regulator (AIRE) gene mutation. The diagnosis includes clinical manifestations in addition to AIRE gene sequencing. SPA type 2 presents with Addison's disease, type 1 diabetes, or autoimmune thyroid disease. Multiple genes have been implicated, including those of the class II major histocompatibility complex. SPA type 3 is characterized by autoimmune thyroid disease and other autoimmune disease, excluding Addison's disease and hypoparathyroidism, 4 genes have been implicated and confer susceptibility. The diagnosis of APS type 2 and type 3 includes clinical manifestations, nevertheless, the determination of autoantibodies can be useful to predict the risk of disease manifestation and to confirm the autoimmune disease in some cases., (Copyright © 2021 Elsevier España, S.L.U.

We studied three members of a single family who had basal ganglia calcifications (BGC): two with BGC alone and one associated with parkinsonism and hypoparathyroidism (H). This family links together BGC and H and may help resolve the apparent controversy about relationship of both.
