Smarca4 gene mutation

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.

3: Miyake N, Tsurusaki Y, Matsumoto N. Numerous BAF complex genes are mutated in Coffin-Siris syndrome. 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 type 2 (RTPS2) (MedGen UID: 413749). SMARCA4 (BAF190, BRG1, FLJ39786, hSNF2b, SNF2, SNF2-BETA, SNF2L4, SNF2LB, SWI2) Tissue specificityi. The RNA specificity category is based on mRNA expression levels in the analyzed samples based on a combination of data from HPA, GTEX and FANTOM5.

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 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).

Truncating mutations in the SMARCA4 gene typically lead to RTPS ,. 23 Oct 2020 Gene therapy is a fitting approach for diseases caused by a single gene mutation , like SMA. It targets the cause of disease by delivering a 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. Chromatin is the network of DNA and protein that packages DNA into chromosomes.

A 61-year-old male patient presented to the hospital with intermittent epigastric pain in the right upper abdomen and SMARCA4 reports in Neuroblastoma (NB) Methods; Mutation distribution; Cancer type details Neuroblastoma Cohorts 6 Samples 562 Mutations 99,664 Driver genes 20 Gene details SMARCA4 Ensembl ID ENSG00000127616 Transcript ID ENST00000344626 Involved in transcriptional activation and repression of select genes by chromatin remodeling (alteration of DNA-nucleosome topology).

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. SMARCA4 (SWI / SNF related, matrix associated, actin dependent regulator of chromatin, subfamily A, member 4) encodes a protein involved in chromatin remodeling, which is important for regulating the binding of transcription factors to DNA (also known as BRG1 and hSNF2β, amongst others; NCBI Gene ID: 6597) 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.

Chromatin-remodeling gene SMARCA4 is comutated with KRAS in LUAD; however, the impact of SMARCA4 mutations on clinical outcome has not been adequately established. This study sought to shed light on the clinical significance of SMARCA4 mu … 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. Therefore, mutations of SMARCA4 represent a genetic factor leading to adverse clinical outcome in lung adenocarcinoma treated by either nonimmunotherapy or immunotherapy.
