SMARCA2
SMARCA2 (BRM, BAF190), gene at 9p24.3, encodes an ATPase subunit of SWI/SNF chromatin remodeling complexes. Mutations cause Nicolaides-Baraitser syndrome; loss is linked to cancer, and SMARCA2 degraders target SMARCA4-mutant tumors.
SMARCA4
SMARCA4 (BRG1) gene, ATPase catalytic subunit of SWI/SNF/BAF chromatin remodeling complexes on chromosome 19; altered in 5-7% of cancers, hallmark of SCCOHT and SMARCA4-deficient thoracic tumors, linked to RTPS2 and Coffin-Siris syndrome.
SMARCA4-deficient sarcoma of thorax
SMARCA4-deficient sarcoma of thorax, also called thoracic SMARCA4-deficient undifferentiated tumor (SMARCA4-UT), is a rare aggressive adult thoracic tumor with SMARCA4/SMARCA2 loss, rhabdoid morphology, strong smoking and male association, and median survival of months.
SMARCA5
SMARCA5 (SNF2H, hISWI), gene ID 8467 at 4q31.21, encodes the 1,052-aa ATPase of human ISWI chromatin remodeling complexes (RSF, ACF, WICH, NoRC, CHRAC), sliding nucleosomes for transcription, replication, DNA repair, meiosis, and cancer; circSMARCA5 is a tumor biomarker.
SMARCAL1
SMARCAL1 (2q35) encodes an ATP-dependent annealing helicase that remodels stalled replication forks; biallelic loss-of-function mutations cause Schimke immuno-osseous dysplasia, an ultra-rare autosomal recessive spondyloepiphyseal dysplasia with nephrotic syndrome and T-cell immunodeficiency.
SMARCB1
SMARCB1 (INI1, SNF5, BAF47) is a tumor-suppressor gene at 22q11.23 encoding a core BAF/SWI-SNF chromatin-remodeling subunit; biallelic loss drives rhabdoid tumors, epithelioid sarcoma, and schwannomatosis.
