Summaries for Porencephaly

NIH Rare Diseases : 49 Porencephaly is a rare condition that affects the central nervous system. People with porencephaly develop fluid-filled cysts or cavities in the brain either before or shortly after birth. The severity of the condition and the associated signs and symptoms vary significantly based on the size, location, and number of cysts. Common features include developmental delay, reduced muscle tone (hypotonia), seizures, macrocephaly (unusually large head size), spastic hemiplegia, speech problems, delayed growth, and intellectual disability. Porencephaly is usually the result of damage from infection or stroke after birth. In these cases, the condition occurs sporadically in people with no family history of the condition. There is an inherited form of the condition called familial porencephaly, which is caused by changes (mutations) in the COL4A1 or COL4A2 genes and is inherited in an autosomal dominant manner. Treatment is based on the signs and symptoms present in each person and may include physical therapy and medication for seizures. Last updated: 3/15/2016

MalaCards based summary : Porencephaly is related to familial porencephaly and hemiplegia, and has symptoms including intellectual disability, seizures and spasticity. An important gene associated with Porencephaly is COL4A1 (Collagen Type IV Alpha 1 Chain), and among its related pathways/superpathways are Focal adhesion and ECM-receptor interaction. The drugs Dobutamine and Adrenergic Agents have been mentioned in the context of this disorder. Affiliated tissues include brain, heart and thalamus, and related phenotypes are growth/size/body region and mortality/aging

NINDS : 50 Porencephaly is an extremely rare disorder of the central nervous system in which a cyst or cavity filled with cerebrospinal fluid develops in the brain.  It is usually the result of damage from stroke or infection after birth (the more common type), but it can also be caused by abnormal development before birth (which is inherited and less common).  Diagnosis is usually made before an infant reaches his or her first birthday.  Symptoms of porencephaly include delayed growth and development, spastic hemiplegia (slight or incomplete paralysis), hypotonia (low muscle tone), seizures (often infantile spasms), and macrocephaly (large head) or microcephaly (small head). Children with porencephaly may have poor or absent speech development, epilepsy, hydrocephalus (accumulation of fluid in the brain), spastic contractures (shrinkage or shortening of the muscles), and cognitive impairment.
