Research output: Contribution to journalArticlepeer-review


Clinical and chromosomal studies are reported in three mentally defective individuals with the triple-X syndrome. Histological evidence of normally maturing Ova in each, and the additional finding of corpora lutea in two, indicate that these patients are potentially fertile. Examination of clinical and laboratory data of all similar cases at present available fails to reveal a characteristic syndrome related to the presence of an extra X chromosome and distinguishable on clinical grounds.
