Uterine leiomyoma cytogenetics. III. Interphase cytogenetic analysis of karyotypically normal uterine leiomyoma excludes possibility of undetected trisomy 12.
Uterine leiomyoma, a benign tumor that histopathologically is rather homogeneous, was recently characterized cytogenetically. About 40% of the investigated tumors are associated with clonal chromosome abnormalities and five different subgroups have been identified, characterized by trisomy 12, t(12;14)(q14-15;q23-24), del(7q), t(1;2)(p36;p24), and 6p rearrangements. In our survey of 76 cases, trisomy 12 was observed in 10% of the abnormal cases. To exclude a possible underscoring of this abnormality, we reexamined 15 of the cases with normal karyotype by interphase cytogenetics using a chromosome 12 alphoid DNA probe.
