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.

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. 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. SMARCA4 Mutation is an inclusion criterion in 2 clinical trials for desmoplastic/nodular medulloblastoma, of which 2 are open and 0 are closed. Of the trials that contain SMARCA4 Mutation and desmoplastic/nodular medulloblastoma as inclusion criteria, 1 is phase 2 (1 open) and 1 is phase 4 (1 open) [ 5 ].

Mutations were detected in 24% of the cancer cell lines, many of them in cells commonly used for lung cancer research. SMARCA4, a central component of the SWI/SNF chromatin-remodeling complex, has been identified as a tumor suppressor gene [227,228]. Several rhabdoid tumors were found to carry inactivating mutations, while SMARCA4 expression is silenced in many human tumor cell lines and tumor tissue. Individual genes were queried for distribution and enrichment among the patients with and without SMARCA4 alterations.

Protein ID ENSP00000343896.

Here we screened for mutations the entire coding sequence of BRG1 (SMARCA4), which encodes the ATPase of the complex, in 59 lung cancer cell lines of the most common histopathological types. Mutations were detected in 24% of the cancer cell lines, many of them in cells commonly used for lung cancer research.

A third non-synonymous PZM in SMARCA4 was identified in an ASD proband in Lim et al., 2017; comparison with a background set of 84,448 privately inherited variants demonstrated that this gene harbored more PZMs than Purpose: SMARCA4 mutations are among the most common recurrent alterations in non–small cell lung cancer (NSCLC), but the relationship to other genomic abnormalities and clinical impact has not been established. Experimental Design: To characterize SMARCA4 alterations in NSCLC, we analyzed the genomic, protein expression, and clinical outcome data of patients with SMARCA4 alterations treated The SMARCA4 gene mutations involved in Coffin-Siris syndrome are germline mutations, which means that they are present in cells throughout the body.

Associated disorders. The SMARCA4 gene is associated with an increased risk of autosomal dominant small cell carcinoma of the ovary, hypercalcemic type ( SCCOHT) ( PMID: 24658002, 24658001) and Coffin-Siris syndrome (MedGen UID: 766163). Studies also suggested SMARCA4 may be associated with autosomal dominant rhabdoid tumor predisposition syndrome

Certain mutations in The SMARCA4 gene encodes a protein that regulates transcription via its helicase and ATPase activities. This gene is often MSK investigators discovered that mutations in the SMARCA4 gene which reduce or eliminate SMARCA4 gene expression and/or protein levels and function View mouse Smarca4 Chr9:21616169-21704230 with: phenotypes, sequences, polymorphisms, proteins, protein coding gene. IDs All Mutations and Alleles. 18 Aug 2020 The SMARCA4 gene provides instructions for making a protein called BRG1, which forms one piece (subunit) of several different protein 25 May 2020 9577Background: The catalytic unit of the SWI/SNF chromatin remodeling complex is encoded by the SMARCA4 gene, which is mutated in 25 May 2020 10.5%, ARID1B 7.2%, SMARCA4 5.5%, PBRM1 4.9%, ARID2 4.8%, Conclusions: Mutations in SWI/SNF genes are widespread, with 1 May 2020 DNA replication stress is a driving force in the generation of genome SMARCA4 mutations in LADC via pharmacological inhibition of ATR 24 Jan 2020 harbor mutations in.

Inactivating SMARCA4 increased cancer SMARCA4 localizes in the nucleus. Function: The SMARCA4 harbours the ATPase activity required for the chromatin remodelling activity of the SWI/SNF complex. This complex uses the energy of ATP hydrolysis to modify the interactions among histones leading to modifications of the chromatin structure and to the regulation of gene expression.

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 [10] and lung. [11] 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.

The DAMAGES score (disease-associated mutation analysis using gene expression signatures), or D score, was developed to combine evidence from de novo loss-of- function mutation with evidence from cell-type- specific gene expression in the mouse brain (specifically translational profiles of 24 specific mouse CNS cell types isolated from 6 different brain regions).

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.
