Summaries for Chung-Jansen Syndrome

NIH Rare Diseases : 52 PHIP-related disorder , also known as Chung-Jansen syndrome , is a rare condition caused by a change in the pleckstrin homology domain-interacting protein (PHIP) gene . The most common signs and symptoms, include mild to severe learning problems, behavior problems, and a tendency toward being overweight. PHIP-related disorder is an autosomal dominant condition. This means that a person with the disorder has a 1 in 2 or 50% chance of passing the condition to each child.

MalaCards based summary : Chung-Jansen Syndrome, also known as developmental delay, intellectual disability, obesity, and dysmorphic features, is related to mood disorder and alacrima, achalasia, and mental retardation syndrome. An important gene associated with Chung-Jansen Syndrome is PHIP (Pleckstrin Homology Domain Interacting Protein). Affiliated tissues include skin, and related phenotypes are intellectual disability and global developmental delay

OMIM : 56 Chung-Jansen syndrome (CHUJANS) is characterized by global developmental delay apparent from infancy, impaired intellectual development or learning difficulties, behavioral abnormalities, dysmorphic features, and obesity. The severity of the phenotype and additional features are variable (summary by Jansen et al., 2018). (617991)

UniProtKB/Swiss-Prot : 73 Chung-Jansen syndrome: An autosomal dominant disorder characterized by developmental delay, intellectual disability, autistic features, anxiety, hypotonia, obesity, and dysmorphic features.
