Uterine leiomyoma is a benign smooth muscle tumor of the myometrium and is the most commonly encountered neoplasm in women of reproductive age. As for most benign tumors, the pathogenesis of leiomyoma remains obscure, especially at the molecular genetic level. The purpose of this study was to perform a genome-wide allelotype analysis to identify potential sites of tumor suppressor gene inactivation. Fifty-two cases of uterine leiomyoma were subjected to allelotype analysis by using matched pairs of tumor and blood DNA. Loss of heterozygosity (LOH) was assessed at 61 microsatellite markers distributed throughout the genome and representing all 41 chromosome arms. In general, LOH was very rare except on chromosome 7q, where LOH was observed in 34% of all informative tumors. Fine-deletion mapping with 25 microsatellite markers from the 7q22 region revealed a minimal deletion unit of approximately 4 cM, bounded by the markers D7S2453 proximally and D7S496 distally, that probably harbors a novel tumor suppressor gene involved in the etiology of this tumor.
