Loss of heterozygosity studies of a variety of human tumors suggest that there are several tumor suppressor genes on chromosome arm 8p. To localize these genes more precisely, we utilized polymerase chain reaction amplification of microsatellite repeat polymorphisms and examined the allelic loss patterns of 17 marker loci on 8p in a population of 59 supraglottic laryngeal squamous cell carcinomas. Twenty-three of these tumors (39%) had an allelic loss at one or more of the markers examined. The allelic loss patterns of these tumors support the presence of at least three different tumor suppressor genes on 8p: one in 8p23, one in 8p22-23, and another in 8p21.

D016133	Polymerase Chain Reaction	In vitro method for producing large amounts of specific DNA or RNA fragments of defined length and sequence from small amounts of short oligonucleotide flanking sequences (primers). The essential steps include thermal denaturation of the double-stranded target molecules, annealing of the primers to their complementary sequences, and extension of the annealed primers by enzymatic synthesis with DNA polymerase. The reaction is efficient, specific, and extremely sensitive. Uses for the reaction include disease diagnosis, detection of difficult-to-isolate pathogens, mutation analysis, genetic testing, DNA sequencing, and analyzing evolutionary relationships.

D016147	Genes, Tumor Suppressor	Genes that inhibit expression of the tumorigenic phenotype. They are normally involved in holding cellular growth in check. When tumor suppressor genes are inactivated or lost, a barrier to normal proliferation is removed and unregulated growth is possible.
