The complexity of brain anomalies underlies the difficulty in recognizing associated syndromes and categorizing the phenotypic variability recognized in genetic mutations. Recent advances in description of the anomalies and molecular studies are allowing a better understanding of the causal heterogeneity of these malformations. This should allow for better prognostic information, recurrence risk counseling and testing for families of children with these major brain anomalies.
