Smarca4 gene mutation

Component of SWI/SNF chromatin remodeling complexes that carry out key enzymatic activities, changing chromatin structure by altering DNA-histone contacts within a nucleosome in an ATP-dependent manner. 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. Heterozygous mutations in SMARCA4 are also associated with Coffin Siris syndrome (4).

Cancer types where is driver 15. Cohorts where is … 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. The discovery was made through the genetic analysis of tumor samples from 12 patients with SCCOHT. Memorial Sloan Kettering genomics researcher Michael Berger sequenced 279 genes that have been implicated in the development or behavior of tumors. This approach, called IMPACT, found that all 12 samples had a mutation in a gene called SMARCA4.

SMARCA4 chromatin remodelling factor is mutated in 11% of Coffin-Siris syndrome (CSS) patients and in almost all small-cell carcinoma of the ovary hypercalcaemic type (SCCOHT) tumours. 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.

Chromatin is the network of DNA and protein that packages DNA into chromosomes. Genotype-phenotype correlation of Coffin-Siris syndrome caused by mutations in SMARCB1, SMARCA4, SMARCE1, and ARID1A.

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.

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. NGS showed a germline SMARCA4 c.3277C>T (p.R1093*)mutation and no abnormal SMARCB1 gene.
