Schizophrenia is associated with high mortality and morbidity. The etiology of schizophrenia remains unclear, studies implicate a multifactorial origin with genetic and environmental factors. The adenomatous polyposis coli (APC) gene has been associated with FAP (familial adenomatous polyposis), and studies have linked it to schizophrenia. However, there are few studies which examine the associ...
New facets to Knudson's [corrected] "two-hit" hypothesis have been proposed recently in relation to adenomatous polyposis coli (APC): protein inactivation may be selected weakly, and the two hits may be interdependent. We reviewed published data on 165 sporadic and 102 familial adenomatous polyposis-associated colorectal tumors with two characterized mutations. Using a Poisson model, we redefin...
Background/aim Chemopreventative therapeutics may be helpful in familial adenomatous polyposis (FAP) management; however, prospective chemopreventative studies are complicated by potential ototoxicity and pre-existing hearing loss. The aim of this study was to establish compare baseline status children adolescents with FAP their unaffected siblings. Patients methods Twenty pediatric patients do...
A 30-year-old female, with no significant family history, came with complaints of intermittent, colicky abdominal pain and abdominal distension of 5 months duration, with significant weight loss. CT abdomen showed multiple polypoidal lesions in the colon. Colonoscopy revealed multiple polyps carpeting the entire colon (Fig. 1A); biopsy of which revealed adenomatous polyps. The patient underwent...
During next generation sequencing (NGS) analysis, many missense mutations were found in a well-known oncogene, many of which were variant of uncertain significance mutations. We recently treated an adult patient with pancreatoblastoma by chemotherapy. Using an NGS cancer panel, we found a previously unreported missense mutation in the 1835 codon of the adenomatous polyposis coli (APC) gene. We ...
Overexpression of the receptor tyrosine kinase Met is an early event in the colorectal adenoma-carcinoma sequence. This suggests a link with disruption of adenomatous polyposis coli-controlled regulation of beta-catenin/T-cell factor (TCF)-mediated transcriptional activation, which is crucial in initiating tumorigenesis. Indeed, in intestinal biopsies from patients with familial adenomatous pol...
Familial adenomatous polyposis (FAP) is an autosomal dominant syndrome leading to colorectal cancer. This disease appears as a result of germline mutation in adenomatous polyposis coli (APC) gene. The aim of the present study is to report the association between two different nucleotide substitutions detected in a family with FAP. In the proband, p.His1172Gln (c.3516delT) was detected in exon 1...
Multiple intestinal neoplasia (Min) mice were originally identified by Moser et al. Min mice have a heterozygous mutation in the tumor suppressor gene, adenomatous polyposis coli (Apc). The APC gene is mutated in familial adenomatous polyposis (FAP). Min mice spontaneously develop intestinal polyps, similar to humans, but mainly in the small intestine. Polyps form as early as approximately 4 we...
BACKGROUND Familial adenomatous polyposis (FAP) is a rare autosomal dominantly inherited disease predisposing to colon cancer and caused by germline mutations in the APC (adenomatous polyposis coli) gene. AIMS We conducted a population based study to evaluate the prevalence and clinical implications of APC mutations among Finnish FAP kindreds. A possible founder effect in parallel with previo...
Attenuated familial adenomatous polyposis (AFAP) is a variant of familial adenomatous polyposis with fewer than one hundred colorectal polyps and a later age of onset of the cancer. Here, we report two cases of AFAP within family members. Each patient demonstrated the same novel germ line mutation in exon 15 of the adenomatous polyposis coli (APC) gene and was successfully managed with sulindac...
