Summaries for Juvenile Polyposis/hereditary Hemorrhagic Telangiectasia Syndrome

About this section
UniProtKB/Swiss-Prot:70 Juvenile polyposis/hereditary hemorrhagic telangiectasia syndrome: JP/HHT syndrome phenotype consists of the coexistence of juvenile polyposis (JIP) and hereditary hemorrhagic telangiectasia (HHT) [MIM:187300] in a single individual. JIP and HHT are autosomal dominant disorders with distinct and non-overlapping clinical features. The former, an inherited gastrointestinal malignancy predisposition, is caused by mutations in SMAD4 or BMPR1A, and the latter is a vascular malformation disorder caused by mutations in ENG or ACVRL1. All four genes encode proteins involved in the transforming-growth-factor-signaling pathway. Although there are reports of patients and families with phenotypes of both disorders combined, the genetic etiology of this association is unknown.

MalaCards based summary: Juvenile Polyposis/hereditary Hemorrhagic Telangiectasia Syndrome, also known as jp/hht syndrome, is related to hereditary hemorrhagic telangiectasia and leukemia, and has symptoms including juvenile gastrointestinal polyposis, pulmonary arteriovenous malformation and clubbing. An important gene associated with Juvenile Polyposis/hereditary Hemorrhagic Telangiectasia Syndrome is SMAD4 (SMAD Family Member 4). Affiliated tissues include skin, lung and liver.

OMIM:52 The JPHT syndrome includes the features of both the juvenile polyposis syndrome (JPS; 174900) and hereditary... (175050) more...
