We have developed a fluorescence-based single-strand conformation polymorphism analytis to detect Haelll-sensitive polymorphic sites in intron I of the 7/53 gene. It is important t o treat the PCR products with Klenow fragment t o remove a 3'-protruding nucleotide from the amplified DNA fragments ad

β¦ Synopsis
Loss of heterozygosity at the TP53 locus occurs frequently in many types of cancer and requires polymorphic markers for detection. Several polymorphisms at the TP53 locus have been described previously, and polymerase chain reaction (PCR)based assays have been developed to detect these polymorphisms. However, these polymorphisms have relatively low levels of heterozygosity and are often uninformative. W e report here the detection of loss of heterozygosity at the TP53 locus in various human cancers by using a highly informative dinucleotide repeat polymorphism. Genes Cham Cancer 589-90 ( I 992).

## Abstract Expression of a recessive phenotype can occur by a number of different mechanisms, such as chromosomal deletion, recombination, and intragenic frameshift mutation or base substitution. To examine the contribution of different mutational events, we isolated and characterized a human fibr
