remarkable genomic stability, with diploid profiles and low mutation load (mean, 5.43 mutations/Mb), including in the three chemotherapy-exposed tumors. All but one SCCOHT cases exhibited 19p13.2-3 copy-neutral LOH. SMARCA4 deleterious mutations were recurrent and accompanied by loss of expression of the SMARCA2 paralog.
It is recommended that individuals with a mutation in the SMARCA4 gene receive and MRI and sonogram of the ovary as well as consider an oophorectomy when they are finished having children. SMAECA4 mutations are inherited in an autosomal dominant manner, meaning each first degree relative (parent, child, and sibling) of an individual with this condition has a 50% chance of inheriting the
Using human cancer cells, Dr. Levine and colleagues then demonstrated that SMARCA4 plays a functional role in promoting or blocking cancer growth. Inactivating SMARCA4 increased cancer SMARCA4 (SWI/SNF related, matrix associated, actin dependent regulator of chromatin, subfamily a, member 4) is a protein-coding gene. Diseases associated with SMARCA4 include mental retardation, autosomal dominant 16, and rhabdoid tumor predisposition syndrome 2. Background SMARCA4 is gene whose protein product participates in chromatin remodeling. Somatic mutations in this gene are associated with non-small cell lung cancer and malignant rhabdoid tumors, and both germline and somatic mutations are seen with small cell carcinoma of the ovary, hypercalcemic type. Gene symbol: Chromosomal location: Gene name: Mutation total: Log in: SMARCA4: 19p13.2: SWI/SNF related, matrix associated, actin dependent regulator of chromatin, subfamily a, member 4: 45 NCBI Description of SMARCA4: The protein encoded by this gene is a member of the SWI/SNF family of proteins and is similar to the brahma protein of Drosophila. Members of this family have helicase and ATPase activities and are thought to regulate transcription of certain genes by altering the chromatin structure around those genes.
Members of this family have helicase and ATPase activities and are thought to regulate transcription of certain genes by altering the chromatin structure around those genes. These polymorphisms impair the function of the promoter and reduce the expression of the SMARCA2 gene. The reduced gene activity likely decreases or alters protein production, which would lead to changes in SWI/SNF complexes. These changes may impair normal cell differentiation, which leads to the overgrowth of certain cell types, causing cancer. Blueprint Genetics' SMARCA4 single gene test SMARCA4 single gene test. including the role of the specific gene in human disease, the mutation profile, Plasmid K785R Smarca4-sfGFP from Dr. Courtney Hodges's lab contains the insert SWI/SNF related, matrix associated, actin dependent regulator of chromatin, subfamily a, member 4 and is published in Nat Struct Mol Biol. 2018 Jan;25(1):61-72.

Heterozygous germline SMARCA4 mutations are associated with an autosomal dominant condition known as rhabdoid tumor predisposition syndrome-2 (OMIM #613325) A subset of patients with Coffin-Siris syndrome, specifically CSS4, a congenital malformation syndrome, bear a heterozygous germline SMARCA4 mutation (OMIM #614609)
Cohorts where is … SMARCA4 localizes in the nucleus. Function: The SMARCA4 harbours the ATPase activity required for the chromatin remodelling activity of the SWI/SNF complex.
Entrez Gene summary for SMARCA2 Gene: The protein encoded by this gene is a member of the SWI/SNF family of proteins and is highly similar to the brahma protein of Drosophila. Members of this family have helicase and ATPase activities and are thought to regulate transcription of certain genes by altering the chromatin structure around those genes.
SWI/SNF related, matrix associated, actin dependent regulator of chromatin, subfamily a, member 4 (SMARCA4) is a gene that encodes a protein that functions in the regulation of transcription via its helicase and ATPase activity. Mutations of SWI/SNF chromatin remodeling complex members SMARCB1/INI1 or (rarely) SMARCA4/Brg1 are the sole recurrent genetic lesions. Epigenetic studies revealed a large number of genes predicted to be affected by differential histone modifications in ATRT, but the role of these genes in the biology of ATRT remains uncertain. SMARCA4 is gene whose protein product participates in chromatin remodeling. Somatic mutations in this gene are associated with non-small cell lung cancer and malignant rhabdoid tumors, and both germline and somatic mutations are seen with small cell carcinoma of the ovary, hypercalcemic type. To date, there are no data identifying an association with more common epithelial carcinomas of the ovary.

Nicolaides-Baraitser syndrome. At least 50 mutations in the SMARCA2 gene have been found to cause Nicolaides-Baraitser syndrome. This condition is characterized by multiple abnormalities, primarily sparse scalp hair, small head size (microcephaly), distinctive facial features, short stature, abnormal fingers, recurrent seizures (epilepsy), and moderate to severe intellectual disability with SMARCA4 SWI/SNF related, matrix associated, actin dependent regulator of chromatin, subfamily a, member 4. Mutation Public 20Q4. Loading table Translocation.
BRG1 (or SMARCA4) is the most frequently mutated chromatin remodeling ATPase in cancer. Mutations in this gene were first recognized in human cancer cell lines derived from adrenal gland and lung. Later it was recognized that mutations exist in a significant frequency of medulloblastoma and pancreatic cancers, and in many other tumor subtypes.

Tumor suppressor SMARCA4 (BRG1), a key SWI/SNF chromatin remodeling gene, is frequently inactivated in cancers and is not directly druggable. We recently uncovered that SMARCA4 loss in an ovarian cancer subtype causes cyclin D1 deficiency leading to susceptibility to CDK4/6 inhibition.
