title: Coincidence between fragile site expression and interstitial deletion of chromosome 11 in a case of myelofibrosis.
abstract: Cytogenetic examination of multiple peripheral blood cultures of a patient with myelofibrosis with myeloid metaplasia revealed the presence of an interstitial deletion of the long arm of chromosome 11, del(11)(q13q21). A folic acid dependent fragile site fra(11)(q13) was found in about 12% of the cells. The possible correlation between constitutional fragile site and acquired chromosomal alteration is discussed briefly.
