Lissencephaly: Variant of LIS1 without Cerebellar Hypoplasia: Phenotype vs Genotype
- Magnetic resonance,
- Prenatal diagnosis,
Classic lissencephaly is a rare and serious brain malformation classified in type 1 and type 2. Type 1 is associated with mutations in the human LIS1 gene, which are numerous and constantly discovered. We present a case of isolated fetal ventriculomegaly with subsequent and unexpected diagnosis of neonatal lissencephaly. The clinical manifestation does not match the genotype, often associated with cerebellar hypoplasia.
