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 [10] and lung. [11]

Keywords: KRAS; SMARCA4 mutation; immunotherapy; lung adenocarcinoma; nonimmunotherapy; prognostics biomarker. 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 gene mutation

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. doi: 10.1038/s41594-017-0007-3.

Lazar,1,2,3 Sandra Stehling-Sun,2,3 Vivek Nandakumar,2 Hao Wang,2 Daniel R. Chee,1,2 Nicholas P. Howard,2 2020-01-06 · Background The SWI/SNF complex is an important chromatin remodeler, commonly dysregulated in cancer, with an estimated mutation frequency of 20%.

10B), had a germline SMARCA4 mutation, BRM gene mutation, chromosome 9 monosomy or BRM deletion and CpG methylation contribute collectively to the loss of BRM expression in poorly differentiated clear cell renal cell carcinoma BRM-741 and BRM-1321 insertion polymorphisms are associated with susceptibility to cancer. 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.

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. 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.

on the basis of data on children with AT/RT carrying a germline SMARCA4 mutation, and their families. The SWI/SNF complex is a major regulator of gene expression and is increasingly thought to play an important role in human cancer, as evidenced by the high frequency of subunit mutations across virtually all cancer types. We previously reported that in preclinical models, malignant rhabdoid tumors, which are deficient in the SWI/SNF core component INI1 (SMARCB1), are selectively killed by SMARCA4 gene product.
