Homologous telomere association of 19q in a female with premature ovarian failure.

Premature ovarian failure (POF) may be due to a variety of genetic mechanisms. We report here, for the first time, telomere association of the long arms of chromosome 19, identified at low frequency (1%) in the peripheral blood cultures of a 30-year-old female with POF. Repeat cultures identified, in addition, the presence of 16q and 22q associations at a lower frequency (0.5%). These consistent observations are suggestive of a non-random event. Their association with POF may just be coincidental or may hypothetically explain it by an abnormal mechanism of chromosome separation, a constitutional telomere anomaly or an unidentified chromosome instability disorder.
