A review of hyperprolactinemia and autoimmunity has found increased prolactin levels associated with production of anti-DNA antibodies, islet cell antibodies, thyroglobulin antibodies, thyroid peroxidase antibodies, adrenocortical antibodies, and transglutaminase antibodies with individuals suffering from systemic lupus erythematosus (SLE), diabetes mellitus type 1, Hashimoto's disease, Addison's disease, and celiac disease [25]. This evidence concerns the gene PRL and hyperprolactinemia.
