Recurring breakpoints of 1p13 approximately p22 in osteochondroma.
Cancer genetics and cytogenetics(2002)
摘要
Cytogenetic studies of osteochondromas are scarce but have previously shown recurring clonal aberrations involving chromosome 8. We have studied a series of eight tumors and have found recurring aberrations not only involving chromosome 8, but also chromosome 1 in five of the seven abnormal tumors. Surprisingly, three of the chromosome 1 aberrations involved pericentric inversions. Four tumors showed aberrations involving the region 1p13 approximately p22 by mechanisms including inversion, insertion, and translocation. These findings indicate that aberrations of chromosome 1p, in a region spanning 1p13 approximately p22, may be nonrandomly involved in the cytogenetic progression of osteochondroma.
