    Abstract:
    We screened 46 suspected families from whole Slovakia for familial adenomatous polyposis (FAP) cancer predisposition. Individuals were enrolled to the adenomatous polyposis coli (APC) gene mutations mapping program at the base of previous clinical investigation. We have used the following techniques: heteroduplex analysis (HDA), protein truncation test (PTT), single strand conformation polymorphism (SSCP) and sequencing for the identification and detailed positional analysis of APC mutations. Around 90% of all detected mutations were found being truncated. The most frequent mutations from this collection were located within codons 1309 and 1061 of exon 15 and represented 15% and 7%, respectively of all tested families. The expressive phenotype, large amount of colorectal polyps and congenital hypertrophy of the retinal pigment epithelium (CHRPE) were associated to all mutations within codons 1309 and 1060.
