Juvenile polyposis/hereditary hemorrhagic telangiectasia syndrome

Preferred Label : Juvenile polyposis/hereditary hemorrhagic telangiectasia syndrome;

Symbol : JPHT;

CISMeF acronym : JPHT; JPS/HHT;

Type : Phenotype, molecular basis known;

Alternative titles and symbols : Juvenile polyposis with hereditary hemorrhagic telangiectasia; Telangiectasia, hereditary hemorrhagic, with juvenile polyposis coli; Polyposis, generalized juvenile, with pulmonary arteriovenous malformation; Jp/hht syndrome; JPS/HHT;

Description : The JP/HHT syndrome phenotype refers of the coexistence of juvenile polyposis syndrome (JPS; 174900) and hereditary hemorrhagic telangiectasia (HHT; 187300) in a single individual. JPS is characterized by hamartomatous polyps occurring throughout the gastrointestinal tract, resulting in an increased risk of gastrointestinal cancer, and HHT is a vascular dysplasia characterized by telangiectases of the skin, and oral and nasal mucosa, epistaxis, and arteriovenous malformations (AVMs) of the lungs, liver, brain, and gastrointestinal tract (summary by Gallione et al., 2010).;

Inheritance : Autosomal dominant;

Molecular basis : Caused by mutation in the mothers against decapentaplegic, Drosophila homolog of, 4 gene (SMAD4, 600993.0007);

Neoplasia : Increased risk of gastrointestinal cancer;

Prefixed ID : #175050;
