A polymorphic region defined by pCN2 (the 3' nontranslated region of N-ras) maps to chromosome 9cen-p12.

Abstract

Abnormalities of chromosome 9p have been reported in human leukemias and lymphomas, and in cell lines lacking the enzyme methylthioadenosine phosphorylase. It has been shown pCN2, the 3' nontranslated region of the N-ras oncogene, crosshybridizes with unknown DNA segments on chromosome 6, 9p, and 22, in addition to the N-ras oncogene itself on chromosome 1p. To use pCN2 to study chromosome 9p abnormalities in malignancies, we undertook to localize the pCN2 crosshybridizing region in chromosome 9p. By analyzing the copy numbers of the pCN2 crosshybridizing bands associated with chromosome 9p among various chromosomally aberrant human cell lines, we mapped the pCN2 hybridizing region to 9cen-p12. Since there is no other available probe in this region, pCN2 should prove very useful in studying abnormalities of chromosome 9p in human malignancies.
