A 48,XXXX female with absence of ovaries.
A 16 1/2-year-old phenotypic female had primary amenorrhea, mild mental retardation, radioulnar synostosis, and other minor anomalies. Chromosome constitution of leukocytes and skin fibroblasts was 48,XXXX. Plasma levels of gonadotropins were increased, and those of estrogens, decreased consistent with ovarian failure. Laparoscopy showed a small midline uterus, and 2 fallopian tubes, and fimbriae. Neither ovaries nor gonadal streaks were seen on either side. This patient appears to represent the first instance of 48,XXXX aneuploidy with documented absence of ovaries.
