Summaries for De Barsy Syndrome

About this section

NIH Rare Diseases:41 De barsy syndrome is a rare genetic disorder characterized mainly by a prematurely aged-looking face (progeria); cloudy corneas; short stature; and intellectual disability. affected individuals can have a wide variety of other signs and symptoms, including loose skin folds due to reduced elasticity (cutis laxa); poor muscle tone (hypotonia); movement disorders; and other features that involve the eyes, face, skin and nervous system. the genetic cause of the condition is not known in most cases, but it is inherited in an autosomal recessive manner. treatment generally focuses on the signs and symptoms present in each individual and may include early eye surgery and physiotherapy to avoid contractures. last updated: 10/31/2011

MalaCards based summary: De Barsy Syndrome, also known as cutis laxa - corneal clouding - intellectual disability, is related to cutis laxa and pycr1-related de barsy syndrome, and has symptoms including abnormality of the fontanelles or cranial sutures, wide nasal bridge and cataract. An important gene associated with De Barsy Syndrome is PYCR1 (pyrroline-5-carboxylate reductase 1), and among its related pathways are Metabolism of amino acids and derivatives and Carbon metabolism. The compounds hydroxyproline and delta(1)pyrroline-5-carboxylate have been mentioned in the context of this disorder. Affiliated tissues include skin, eye and bone.
