Living with Classic lissencephaly
A rare brain development condition where the surface of the brain is unusually smooth.
Understanding Classic lissencephaly
It belongs to a group of conditions linked to changes in the PAFAH1B1 gene, including Miller-Dieker syndrome, isolated lissencephaly sequence, and less commonly subcortical band heterotopia. In lissencephaly, the brain surface has no normal folds (agyria) or very broad, shallow folds (pachygyria). Isolated lissencephaly sequence involves developmental delay, intellectual disability, and seizures.
