Endocrinopathy and IgA deficiency
Clinical Immunology and Immunopathology, 1973Abstract Three cases of IgA deficiency occurring in association with endocrine hypofunction—Turner's syndrome, hypothyroidism, and diabetes—are described. The significance of IgA deficiency associated with chromosome abnormalities are discussed in view of the present finding of IgA deficiency in a patient with Turner's syndrome displaying a karyotype
