Malformations of Cortical Development (MCD)
Different types of MCD are recognized based on anatomy. They carry names like microcephaly (small brain and head), schizencephaly (fluid filled clefts in the brain), pachygyria (a cortex with thicker, fewer folds) and polymicrogyria (cortex with many small folds).

Gene scan finds link across array of childhood brain disorders
Mutations in a single gene can cause several types of developmental brain abnormalities that experts have traditionally considered different disorders. With support from the National Institutes of Health, researchers found those mutations through whole exome sequencing — a new gene scanning technology that cuts the cost and time of searching for rare mutations.

Whole exome sequencing can be applied to dozens of other rare genetic disorders where the culprit genes have so far evaded discovery, he said.
Such information can help couples assess the risk of passing on genetic disorders to their children. It can also offer insights into disease mechanisms and treatments.
The research is funded in part by a $2.9 million stimulus grant from NIH’s National Institute of Neurological Disorders and Stroke (NINDS) made possible by the American Recovery and Reinvestment Act.
“This study demonstrates a powerful new tool for discovering the cause of tough-to-crack genetic disorders,” said NINDS director Story Landis, Ph.D. “It also exemplifies how Recovery Act support to the NIH community is successfully driving biomedical technology and innovation.”
