Associated disorders. 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

Tumor suppressor SMARCA4 (BRG1), a key SWI/SNF chromatin remodeling gene, is frequently inactivated in cancers and is not directly druggable. We recently uncovered that SMARCA4 loss in an ovarian cancer subtype causes cyclin D1 deficiency leading to susceptibility to CDK4/6 inhibition.

Without the functional  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  The SMARCA4 gene mutations involved in Coffin-Siris syndrome are germline mutations, which means that they are present in cells throughout the body. The mutations change single protein building blocks (amino acids) in or remove an amino acid from the BRG1 protein. Therefore, mutations of SMARCA4 represent a genetic factor leading to adverse clinical outcome in lung adenocarcinoma treated by either nonimmunotherapy or immunotherapy.

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. 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.

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

Nicolaides-Baraitser syndrome. At least 50 mutations in the SMARCA2 gene have been found to cause Nicolaides-Baraitser syndrome. This condition is characterized by multiple abnormalities, primarily sparse scalp hair, small head size (microcephaly), distinctive facial features, short stature, abnormal fingers, recurrent seizures (epilepsy), and moderate to severe intellectual disability with SMARCA4 SWI/SNF related, matrix associated, actin dependent regulator of chromatin, subfamily a, member 4.

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] 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. 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 ].

SMAECA4 mutations are inherited in an autosomal dominant manner, meaning each first degree relative (parent, child, and sibling) of an individual with this condition has a 50% chance of inheriting the SMARCA4 mutations (both somatic and germline mutations) are cur- rently recognized as genetic driver events in almost all small cell carcinomas of the ovary, hypercalcemic type (SCCOHT), which is the most common undifferentiated ovarian malig- nancy in women under 40years of age [ 4, 5]. SMARCA4 mutations were detected mainly in SMARCA4-lost and heterogeneous pattern of SMARCA4-lost gastric cancer, while ARIDIA mutations mainly in SMARCA4-reduced and heterogenous pattern of SMARCA4-reduced gastric cancer , which is consistent with the finding report in the current study case. 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.

Experimental Design: To characterize SMARCA4 alterations in NSCLC, we analyzed the genomic, protein expression, and clinical outcome data of patients with SMARCA4 alterations treated The SMARCA4 gene mutations involved in Coffin-Siris syndrome are germline mutations, which means that they are present in cells throughout the body. The mutations change single protein building blocks (amino acids) in or remove an amino acid from the BRG1 protein. BRG1 (or SMARCA4) is the most frequently mutated chromatin remodeling ATPase in cancer.
