Mutations in SMARCB1 and in other Coffin–Siris syndrome genes lead to various brain midline defects

Abstract

Why and how mutations in genes encoding BAF complex components lead to distinct disease entitites remains unresolved. In this study, authors establish the first Smarcb1 mutant mouse model with multiple brain abnormalities recapitulating human Coffin–Siris syndrome and show that one prominent midline abnormality, corpus callosum agenesis, is due to midline glia aberrations.
