SMARCA4 and cardiovascular disorder: Further follow-up studies, complementary to those here, will be required to clarify the role of the SWI/SNF complex containing BAF60c-BRM, its differences from the BAF60c-BRG1 complex in regulating VSMC biology, and the potentially specific contributions of both the BAF60c-BRG1– and BAF60c-BRM–containing SWI/SNF complexes to different cardiovascular diseases.
