چکیده
|
Familial adenomatous polyposis (fap) is responsible for < 1% of colorectal cancer (crc) cases and is inherited an autosomal dominant trait. patients generally present hundreds to thousands of adenomas and develop colorectal cancer by age 35- 40 if left untreated. here we report four patients with germline frameshift mutation (small deletion) at exon 15 of adenomatous polyposis coli (apc) tumor suppressor gene. peripheral blood samples were collected from patients and exon 15 of the apc gene was studied by direct sequencing after genomic dna extraction. four frameshift mutations were detected. two patients had 5 bp deletion, c.3927_3931delaaaga and two siblings presented deletion at codon 849 (c.2547_2548delta p.asp849fsx62). this study was the first report of genetic screening in iranian fap patients. in contrast to other studies we revealed that one patient with mutation at codon 1309 had an attenuated phenotype.
