Abstract
A rare association of chromosomal, immunological and endocrine defects is described in a young woman with short stature, recurrent pulmonary infections and primary amenorrhea. Cytogenetic studies showed a 45, X karyotype in 65% of peripheral blood lymphocytes and 46,Xr(X) (p22q27) karyotype in the remaining 35%. Severe immunodeficiency was revealed by phenotypical and functional studies and a selective gonadotropin defect was disclosed by endocrinological investigations. An attempt is made to explain the coexistence of the three abnormal pictures.
