Abstract:
The premature ovarian failures with underlying chromosomal abnormalities are normally X-linked, although their associations with the autosomal and the Robertsonian translocations are also possible. Here, we are reporting a case of premature ovarian failure which was associated with a translocation between the long arm of chromosome 7 at q11.23 and the short arm of chromosome 5 at p15.3. The proband was a 26-year-old Malay woman who presented with premature ovarian failure, who was referred for cytogenetic testing due to the suspicion of a chromosomal anomaly. Her physical examination revealed that she had no abdominal or pelvic masses and that she had normal secondary sexual characteristics. Her medical history as well, revealed no points for concern. However, a consanguineous relationship existed, as the patient's paternal grandmother and maternal grandfather were biological cousins. Our present case indicated that region p15.3 of chromosome 5 and region q11.23 of chromosome 7 possibly carried essential genes for the ovarian function and that they postulated a link between the consanguinity and the chromosomal abnormalities.
