Summaries for Megalencephaly

NINDS : 55 Megalencephaly, also called macrencephaly, is a condition in which an infant or child has an abnormally large, heavy, and usually malfunctioning brain. By definition, the brain weight is greater than average for the age and gender of the child. Head enlargement may be evident at birth or the head may become abnormally large in the early years of life. Megalencephaly is thought to be related to a disturbance in the regulation of cell production in the brain. In normal development, neuron proliferation - the process in which nerve cells divide to form new generations of cells - is regulated so that the correct number of cells is produced in the proper place at the appropriate time. In a megalencephalic brain, too many cells are produced either during development or progressively as part of another disorder, such as one of the neurofibromatoses or leukodystrophies. Symptoms of megalencephaly include delayed development, seizures, and corticospinal (brain cortex and spinal cord) dysfunction. Megalencephaly affects males more often than females. Unilateral megalencephaly or hemimegalencephaly is a rare condition that is characterized by the enlargement of one side of the brain. Children with this disorder may have a large, asymmetrical head accompanied by seizures, partial paralysis, and impaired cognitive development. Megalencephaly is different from macrocephaly (also called megacephaly or megalocephaly), which describes a big head, and which doesn’t necessarily indicate abnormality. Large head size is passed down through the generations in some families.

MalaCards based summary : Megalencephaly, also known as macroencephaly, is related to megalencephaly-polymicrogyria-polydactyly-hydrocephalus syndrome 1 and megalencephaly-capillary malformation-polymicrogyria syndrome. An important gene associated with Megalencephaly is SCN1A (Sodium Voltage-Gated Channel Alpha Subunit 1), and among its related pathways/superpathways are PI3K-Akt signaling pathway and Focal Adhesion. The drugs Miconazole and Sirolimus have been mentioned in the context of this disorder. Affiliated tissues include brain, spinal cord and cortex, and related phenotypes are macrocephaly and short neck
