SMARCA4 is an inclusion criterion in 3 clinical trials for rhabdoid tumor, of which 3 are open and 0 are closed. Of the trials that contain SMARCA4 status and rhabdoid tumor as inclusion criteria, 2 are phase 1 (2 open) and 1 is phase 2 (1 open) [ 4 ]. Endometrial Endometrioid Adenocarcinoma +.


A mutation in the SMARCA4 gene can cause Coffin-Siris syndrome, but can also give rise to several cancer predisposition syndromes. 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.

Tumor tissue from both patients also carried a somatic truncating mutation in the SMARCA4 gene, consistent with the '2-hit' hypothesis of tumorigenesis. In affected members of 4 unrelated families with RTPS2 presenting as small cell carcinoma of the ovary, hypercalcemic type (SCCOHT), Witkowski et al. (2014) identified 4 different germline heterozygous mutations in the SMARCA4 gene (603254 2019-03-05 The SMARCA4 gene provides instructions for making a protein called BRG1, which forms one piece (subunit) of several different protein groupings called SWI/SNF protein complexes. SWI/SNF complexes regulate gene activity (expression) by a process known as chromatin remodeling.

These changes may impair normal cell differentiation, which leads to the overgrowth of certain cell types, causing cancer. 2020-01-06 · Background The SWI/SNF complex is an important chromatin remodeler, commonly dysregulated in cancer, with an estimated mutation frequency of 20%. ARID1A is the most frequently mutated subunit gene. Almost nothing is known about the other familiar members of the SWI/SNF complexes, SMARCA2 (BRM), SMARCA4 (BRG1) and SMARCB1 (INI1), in oesophageal adenocarcinoma (EAC). 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. doi: 10.1038/s41594-017-0007-3.

The protein encoded by this gene is a member of the SWI/SNF family of Biallelic inactivation of the SMARCA4 gene correlates with loss of nuclear SMARCA4 (BRG1) expression by immunohistochemistry (Fig. 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.

Smarca4 gene mutation

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.

Jelinic et al. (2014) identified biallelic inactivating somatic mutations in the SMARCA4 gene in 100% of 12 SCCOHT samples. The mutations were found by exome sequencing of 279 cancer-related genes in these tumors and were confirmed by Sanger sequencing.

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].

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 ]. 2017-11-01 · 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. SMARCA4 GENIE Cases - Top Diseases The most common alterations in SMARCA4 are SMARCA4 Mutation (3.78%), SMARCA4 Amplification (0.28%), SMARCA4 Loss (0.10%), SMARCA4 T910M (0.09%), and SMARCA4 R1192H (0.04%) [ 3 ].

Smarca4 gene mutation

Relevance to Autism. Two de novo missense variants in the SMARCA4 gene were identified in ASD probands from the Autism Sequencing Consortium in De Rubeis et al., 2014; both of these variants were later determined to be postzygotic mosaic mutations (PZMs) in Lim et al., 2017. 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 While SMARCA4 is considered a tumor suppressor gene, both loss of protein expression as well as protein upregulation have been associated with neoplasia ( Sci Rep 2018;8:2043, Cancer Res 2003;63:560 ) It is frequently mutated in a variety of cancer cell lines ( Hum Mutat 2008;29:617 )

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

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.

Missense mutations with gain-of-function or dominant-negative effects are associated with CSS, whereas inactivating mutations, leading to loss of SMARCA4 expression, have been exclusively found in SCCOHT. 2017-03-14 · genes, such as those involved in differentiation and tumor suppression.
