BRG1

 

Pathology

-  somatic mutation in

-  BRG1/BRM expression was found lost in 10% of primary lung tumors correlating with a poor prognostic outcome.

Animal models

-  Whereas Brg1-deficiency causes early embryonic lethality in mice, Brg1+/- animals are prone to epithelial tumors, possibly due to haploinsufficiency for Brg1 in tumor suppression, as the outgrowing tumors retained the remaining wild-type Brg1 allele. Brm-deficient mice are viable, likely via adaptive upregulation of Brg1.
