title: Short stature in a 46,XX male adolescent.
abstract: We describe a patient with a 46,XX karyotype who was assessed because of short stature and a subnormal rate of linear growth. The patient had normal male external genitalia. Endocrinologic analysis revealed elevated levels of luteinizing hormone and follicle-stimulating hormone but an exaggerated gonadotropin response to luteinizing hormone-releasing hormone stimulation. The growth hormone response to insulin-induced hypoglycemia was also exaggerated. All sequences examined on the sex-determining region Y gene were present. The diagnosis was 46,XX male with the major manifestation of short stature.
