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 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.

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. Mutations of SWI/SNF chromatin remodeling complex members SMARCB1/INI1 or (rarely) SMARCA4/Brg1 are the sole recurrent genetic lesions.

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.

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 ].

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.

Methods We analysed a large 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.

Deficient. 11 Feb 2019 Loss-of-function mutations inactivate SMARCA4 in approximately 10% of non- small-cell lung cancers (NSCLC) and nearly 100% of small cell 22 Feb 2021 Because germline mutations result in an increased risk of carriers SMARCB1 and SMARCA4 are tumor suppressor genes playing a critical Recently, mutations in a. 2nd locus of the SWI/SNF complex, the SMARCA4 gene , also known as BRG1, were found in rhabdoid tumors with retention of Using this approach we identified new missense mutations in CBL, NOTCH1, PIK3R4 and SMARCA4 genes.

Frequently identified features in Coffin-Siris syndrome are intellectual disability, feeding difficulties, coarse facial features, speech delay, small or absent fifth finger or toe nail(s) and hypertrichosis. remarkable genomic stability, with diploid proﬁles and low mutation load (mean, 5.43 mutations/Mb), including in the three chemotherapy-exposed tumors.

N2 - Background SMARCA4 is gene whose protein product participates in chromatin remodeling. 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. Gene symbol: Chromosomal location: Gene name: Mutation total: Log in: SMARCA4: 19p13.2: SWI/SNF related, matrix associated, actin dependent regulator of chromatin 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.
