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

Mutations in genes encoding components of BAF (BRG1/BRM-associated factor) chromatin remodeling complexes cause neurodevelopmental disorders and tumors. The mechanisms leading to the development of these two disease entities alone or in combination remain unclear. We generated mice with a heterozygous nervous system-specific partial loss-of-function mutation in a BAF core component gene, Smarcb1 . These Smarcb1 mutant mice show various brain...
