FAP is a colorectal cancer (CRC) predisposition syndrome that can manifest in either classic or attenuated form. Classic FAP is characterized by hundreds to thousands of adenomatous colonic polyps, beginning on average at age 16 years (range 7-36 years). For those with the classic form of FAP, 95% of individuals have polyps by age 35 years; CRC is inevitable without colectomy. The mean age of CRC diagnosis in untreated individuals is 39 years (range 34-43 years). The attenuated form is characterized by multiple colonic polyps (average of 30), more proximally located polyps, and a diagnosis of CRC at a later age than in classic FAP. For those with an attenuated form, there is a 70% lifetime risk of CRC and the mean age of diagnosis is 50-55 years. Extracolonic manifestations are variably present and include polyps of the stomach and duodenum, osteomas, dental abnormalities, congenital hypertrophy of the retinal pigment epithelium (CHRPE), benign cutaneous lesions, desmoid tumors, adrenal masses, and other associated cancers. GAPPS is characterized by proximal gastric polyposis, increased risk of gastric adenocarcinoma, and no duodenal or colonic involvement in most individuals reported." /><meta name="robots" content="index,nofollow,noarchive" />

FAP is a colorectal cancer (CRC) predisposition syndrome that can manifest in either classic or attenuated form. Classic FAP is characterized by hundreds to thousands of adenomatous colonic polyps, beginning on average at age 16 years (range 7-36 years). For those with the classic form of FAP, 95% of individuals have polyps by age 35 years; CRC is inevitable without colectomy. The mean age of CRC diagnosis in untreated individuals is 39 years (range 34-43 years). The attenuated form is characterized by multiple colonic polyps (average of 30), more proximally located polyps, and a diagnosis of CRC at a later age than in classic FAP. For those with an attenuated form, there is a 70% lifetime risk of CRC and the mean age of diagnosis is 50-55 years. Extracolonic manifestations are variably present and include polyps of the stomach and duodenum, osteomas, dental abnormalities, congenital hypertrophy of the retinal pigment epithelium (CHRPE), benign cutaneous lesions, desmoid tumors, adrenal masses, and other associated cancers. GAPPS is characterized by proximal gastric polyposis, increased risk of gastric adenocarcinoma, and no duodenal or colonic involvement in most individuals reported. [from <a title="GeneReviews" href="https://www.ncbi.nlm.nih.gov/books/NBK1116" class="defSource" target="_blank">GeneReviews</a>]</div><div class="spaceAbove"><strong>Full text of <i>GeneReview</i> (by section):</strong><br /><a class="medgenPMinfo" href="/books/NBK1345#fap.Summary" target="NBK1345">Summary</a>  |  <a class="medgenPMinfo" href="/books/NBK1345#fap.GeneReview_Scope" target="NBK1345">GeneReview Scope</a>  |  <a class="medgenPMinfo" href="/books/NBK1345#fap.Diagnosis" target="NBK1345">Diagnosis</a>  |  <a class="medgenPMinfo" href="/books/NBK1345#fap.Clinical_Characteristics" target="NBK1345">Clinical Characteristics</a>  |  <a class="medgenPMinfo" href="/books/NBK1345#fap.Genetically_Related_Allelic_Disorder" target="NBK1345">Genetically Related (Allelic) Disorders</a>  |  <a class="medgenPMinfo" href="/books/NBK1345#fap.Differential_Diagnosis" target="NBK1345">Differential Diagnosis</a>  |  <a class="medgenPMinfo" href="/books/NBK1345#fap.Management" target="NBK1345">Management</a>  |  <a class="medgenPMinfo" href="/books/NBK1345#fap.Genetic_Counseling" target="NBK1345">Genetic Counseling</a>  |  <a class="medgenPMinfo" href="/books/NBK1345#fap.Resources" target="NBK1345">Resources</a>  |  <a class="medgenPMinfo" href="/books/NBK1345#fap.Molecular_Genetics" target="NBK1345">Molecular Genetics</a>  |  <a class="medgenPMinfo" href="/books/NBK1345#fap.Chapter_Notes" target="NBK1345">Chapter Notes</a>  |  <a class="medgenPMinfo" href="/books/NBK1345#fap.References" target="NBK1345">References</a></div><div class="spaceAbove"><strong>Authors:</strong><br />

<div class="portlet_content ln"><div class="mgSection"><strong>From OMIM</strong><br />Familial adenomatous polyposis-1 (FAP1) is an autosomal dominant disorder characterized by predisposition to cancer. Affected individuals usually develop hundreds to thousands of adenomatous polyps of the colon and rectum, a small proportion of which will progress to colorectal carcinoma if not surgically treated. Gardner syndrome is a variant of FAP in which desmoid tumors, osteomas, and other neoplasms occur together with multiple adenomas of the colon and rectum (Nishisho et al., 1991).&#13;
Rustgi (2007) reviewed the genetics of hereditary colon cancer, including APC.&#13;

People with the classic type of familial adenomatous polyposis may begin to develop multiple noncancerous (benign) growths (polyps) in the colon as early as their teenage years. Unless the colon is removed, these polyps will become malignant (cancerous). The average age at which an individual develops colon cancer in classic familial adenomatous polyposis is 39 years. Some people have a variant of the disorder, called attenuated familial adenomatous polyposis, in which polyp growth is delayed. The average age of colorectal cancer onset for attenuated familial adenomatous polyposis is 55 years.<br /><br />In people with classic familial adenomatous polyposis, the number of polyps increases with age, and hundreds to thousands of polyps can develop in the colon. Also of particular significance are noncancerous growths called desmoid tumors. These fibrous tumors usually occur in the tissue covering the intestines and may be provoked by surgery to remove the colon. Desmoid tumors tend to recur after they are surgically removed. In both classic familial adenomatous polyposis and its attenuated variant, benign and malignant tumors are sometimes found in other places in the body, including the duodenum (a section of the small intestine), stomach, bones, skin, and other tissues. People who have colon polyps as well as growths outside the colon are sometimes described as having Gardner syndrome.<br /><br />A milder type of familial adenomatous polyposis, called autosomal recessive familial adenomatous polyposis, has also been identified. People with the autosomal recessive type of this disorder have fewer polyps than those with the classic type. Fewer than 100 polyps typically develop, rather than hundreds or thousands. The autosomal recessive type of this disorder is caused by mutations in a different gene than the classic and attenuated types of familial adenomatous polyposis.  <a target="_blank" href="https://medlineplus.gov/genetics/condition/familial-adenomatous-polyposis">https://medlineplus.gov/genetics/condition/familial-adenomatous-polyposis</a></div></div>

<div class="spaceAbove">Medulloblastoma is the most common brain tumor in children. It accounts for 16% of all pediatric brain tumors, and 40% of all cerebellar tumors in childhood are medulloblastoma. Medulloblastoma occurs bimodally, with peak incidences between 3 and 4 years and 8 and 9 years of age. Approximately 10 to 15% of medulloblastomas are diagnosed in infancy. Medulloblastoma accounts for less than 1% of central nervous system (CNS) tumors in adults, with highest incidence in adults 20 to 34 years of age. In 1 to 2% of patients, medulloblastoma is associated with Gorlin syndrome (109400), a nevoid basal carcinoma syndrome. Medulloblastoma also occurs in up to 40% of patients with Turcot syndrome (see 276300). Medulloblastoma is thought to arise from neural stem cell precursors in the granular cell layer of the cerebellum. Standard treatment includes surgery, chemotherapy, and, depending on the age of the patient, radiation therapy (Crawford et al., 2007).&#13; Millard and De Braganca (2016) reviewed the histopathologic variants and molecular subgroups of medulloblastoma. Pretreatment prognosis of medulloblastoma has been refined by histopathologic subclassification into the following variants: large-cell medulloblastoma, anaplastic medulloblastoma, desmoplastic/nodular medulloblastoma, and medulloblastoma with extensive nodularity (MBEN). The latter 2 groups have been shown to have a significantly superior prognosis as compared to the large cell and anaplastic groups in young children. At the molecular level, medulloblastomas have been categorized into the following subgroups: wingless (WNT), sonic hedgehog (SHH), group 3, and group 4. Each subgroup is characterized by a unique set of genetics and gene expression as well as demographic and clinical features.</div>
