SMARCA4 germline gene mutation in a patient with epithelial ovarian: A case report
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. To date, there are no data identifying an association with more common epithelial carcinomas...
متن کاملDual loss of the SWI/SNF complex ATPases SMARCA4/BRG1 and SMARCA2/BRM is highly sensitive and specific for small cell carcinoma of the ovary, hypercalcaemic type
Small cell carcinoma of the ovary, hypercalcaemic type (SCCOHT) is a lethal and sometimes familial ovarian tumour of young women and children. We and others recently discovered that over 90% of SCCOHTs harbour inactivating mutations in the chromatin remodelling gene SMARCA4 with concomitant loss of its encoded protein SMARCA4 (BRG1), one of two mutually exclusive ATPases of the SWI/SNF chromati...
متن کاملGermline SMARCA4 mutations in patients with ovarian small cell carcinoma of hypercalcemic type
BACKGROUND SMARCA4 mutations have recently been identified as driving lesions of the ovarian small cell carcinoma of hypercalcemic type (SCCHT). Familial occurrence of this neoplasm was described previously. METHODS We looked for germline SMARCA4 alterations in eight patients with the SCCHT. DNA was extracted from probands' and their relatives' blood. The SMARCA4 coding sequence, previously f...
متن کاملProphylactic oophorectomy for hereditary small cell carcinoma of the ovary, hypercalcemic type
•Prophylactic oophorectomy can prevent small cell carcinoma of the ovary, hypercalcemic type in carriers of germline SMARCA4 mutations.•Unaffected SMARCA4 mutation carriers who desire children may be best served by oocyte cryopreservation prior to prophylactic oophorectomy.
متن کاملLoss of the tumor suppressor SMARCA4 in small cell carcinoma of the ovary, hypercalcemic type (SCCOHT).
Small cell carcinoma of the ovary, hypercalcemic type (SCCOHT), is a rare and understudied cancer with a dismal prognosis. SCCOHT's infrequency has hindered empirical study of its biology and clinical management. However, we and others have recently identified inactivating mutations in the SWI/SNF chromatin remodeling gene SMARCA4 with concomitant loss of SMARCA4 protein in the majority of SCCO...
