J. Weaverfeldhaus et al., LOCALIZATION OF A PUTATIVE TUMOR-SUPPRESSOR GENE BY USING HOMOZYGOUS DELETIONS IN MELANOMAS, Proceedings of the National Academy of Sciences of the United Statesof America, 91(16), 1994, pp. 7563-7567
The p21 region of human chromosome 9 is thought to contain a gene (MLM
) involved in genetic susceptibility to melanoma and a gene or genes t
hat influence progression of certain other tumors. Genomic clones that
span a large region in 9p21 surrounding the presumptive tumor suppres
sor gene(s) have been isolated. A set of sequence-tagged sites in this
region has been developed. By using these markers and others previous
ly reported, the 9p21 region has been studied by physical mapping in 8
4 melanoma cell lines. A putative tumor suppressor gene, perhaps MLM i
tself, has been localized to a region of less than 40 kb that lies pro
ximal (centromeric) to the alpha-interferon gene cluster.
