Prevalence of multiple forms of autoimmunity in Egyptian patients with Turner syndrome: relation to karyotype.

Our study aimed to investigate: the prevalence of autoantibodies related to organ-specific disease; the prevalence of some autoimmune diseases (AID) in Egyptian Turner syndrome (TS) patients; and the association of autoimmunity with patients' karyotypes. Eighty TS patients were subjected to history, auxological assessment and measurement of antithyroid peroxidase antibody (ATPOAb), antithyroglobulin antibody (ATGAb), anti-tissue transglutaminase IgA antibodies (ATTIgAAb), anti-glutamic acid decarboxylase-65 antibodies (GAD-65-Ab) and anti-adrenal cortex antibodies (AACAb). Of the 80 TS patients, 54 (67.
