BRCA1 and BRCA2 are highly distinct genes, despite the similarity in their acronyms. Characteristics About one-tenth of all breast cancer cases exhibit a familial pattern of inheritance. Of these familial cases, germline mutations in either one of two genes, BRCA1 or BRCA2 , occur in 20鈥 ...
摘要: BRCA1 and BRCA2 are cancer-predisposition genes, germ line mutations which are associated with a high risk of developing breast cancer, ovarian cancer, and other cancers. Much information has been...DOI: 10.1007/978-3-642-16483-5_718 ...
Breast Cancer Genes Abnormalities (mutations) in two genes -- BRCA1 and BRCA2 - are the most common causes of hereditary breastcancer, accounting for about 20% to 25% of cases. Usually, BRCA genes help to prevent cancer by creating proteins that keep cells from growing abnormally. If you ...

Mutations in the BRCA1 and BRCA2 genes lead to an increased susceptibility to breast, ovarian, and other cancers. It is estimated that 3%-8% of all women with breast cancer will be found to carry a mutation in 1 of these genes. Families with multiple affected first-degree relatives and ...
Women who believe they may be at high risk of hereditary breast cancer should consider talking to a genetic counselor. This may influence the type and frequency of breast cancer screening they need.Some women inherit mutations in the so-call breast cancer genes—BRCA1 and BRCA2. These genetic...
In this scenario, the mutations are not inherited and they do not cluster in families. In hereditary breast cancer, the specific genetic factors involved will determine the inherited cancer risk. Inherited mutations in the BRCA1 or BRCA2 genes have been well-described, but mutations in ATM, ...

BRCA1 and BRCA2 are tumor suppressor genes, familial mutations in which account for 5% of breast cancer cases in the USA annually. Germ line mutations in BRCA1 that truncate or inactivate the protein lead to a cumulative risk of breast cancer, by age 70, of up to 80%, whereas the risk...
Abstract The hereditary breast and ovarian cancer susceptibility genes, BRCA1 and BRCA2, have established roles in genome integrity maintenance and in the control of homologous recombination. Recent work has produced valuable insights into the mechanisms of action of the gene products. This review summ...
