Moreover, a MIB-1 immunostain showed only rare positive cells, and IDH1 (R132H mutation) immunostain was negative (not shown). Researchers believe that many other genes are probably involved in the different forms of polymicrogyria.

Cortical dysplasia is a condition in which nerve cells in the outer part of a babys brain do not develop properly before birth. It also introduced a novel multi-layered classification scheme combining histopathological diagnosis, genetic and neuroimaging findings to provide an integrated final diagnosis. Several forms of the condition, including bilateral frontoparietal polymicrogyria (which is associated with mutations in the ADGRG1 gene), have an autosomal recessive pattern of inheritance.

Here also, we are willing to provide you with the support that you need. Some people with polymicrogyria have relatives with the disorder, while other affected individuals have no family history of the condition. These genes are thought to prevent cells from growing too fast or in an out-of-control way. This condition causes severe intellectual disability, problems with movement, and seizures that are difficult or impossible to control with medication.
