A reciprocal translocation (X;11) in a female with gonadal dysgenesis.


A 24-year-old female patient was referred for evaluation of primary amenorrhea. Endocrine studies showed elevated gonadotropins, consistent with gonadal failure. At laparoscopy, a normal nulligravid uterus, normal fallopian tubes, and bilateral streak gonads were observed. Histologic studies showed that the left gonad consisted entirely of fibrous tissue, confirming the presence of streak gonads. Chromosome banding studies of peripheral blood and cultures of tissue from the left gonad demonstrated a 46,X,rcp(X;11)(q22;q13) karyotype. A review of reports of X-autosome reciprocal translocations indicated that abnormal gonadal development is associated with break-points in the mid-region of the long arm of the X chromosome.
