Congenital Nervous System Abnormality, also known as congenital nervous system disorder, is related to microcephaly and lissencephaly. An important gene associated with Congenital Nervous System Abnormality is PNKP (Polynucleotide Kinase 3'-Phosphatase), and among its related pathways/superpathways are Lissencephaly gene (LIS1) in neuronal migration and development and PAFAH1B1 copy number variation. Related phenotypes are nervous system and growth/size/body region
