Description
Periventricular nodular heterotopia is a disorder of neuronal migration in which neurons fail to migrate appropriately from the ventricular zone to the cortex during development, resulting in the formation of nodular brain tissue lining the ventricles.

This panel was developed and used by the Australian Genomics Brain Malformations Flagship. It is maintained by VCGS and a consensus panel used by RMH.
