Abstract Alterations in chromosomal region 9p21-22 are among the most frequently encountered cytogenetic changes present in a number of human malignancies. In addition, the causative genes of a number of hereditary cancers have been genetically mapped to this region. We describe the isolation and precise localization of four novel polymorphic markers and a previously identified marker, D9S1846, from this region. Moreover, we have identified a retroposon-rich area within this oncogenic region containing a processed H3.3B pseudogene flanked by an L1 sequence and an Alu element. Together, these finely mapped and ordered reagents should prove useful for genetic mapping, sequencing, and loss of heterozygosity studies of the 9p21-22 region.
