Prevalence of BRCA1 and BRCA2 mutations in unselected breast cancer patients from Greece

چکیده
The prevalence of BRCA1 and BRCA2 mutations among breast cancer patients in Peru has not yet been explored. We enrolled 266 women with breast cancer from a National cancer hospital in Lima, Peru, unselected for age or family history. DNA was screened with a panel of 114 recurrent Hispanic BRCA mutations (HISPANEL). Among the 266 cases, 13 deleterious mutations were identified (11 in BRCA1 and 2 in BRCA2), representing 5% of the total. The average age of breast cancer in the mutation-positive cases was 44 years. BRCA1 185delAG represented 7 of 11 mutations in BRCA1. Other mutations detected in BRCA1 included: two 2080delA, one 943ins10, and one 3878delTA. The BRCA2 3036del4 mutation was seen in two patients. Given the relatively low cost of the HISPANEL test, one should consider offering this test to all Peruvian women with breast or ovarian cancer.

The importance of BRCA1 and BRCA2 genes mutations in breast cancer development
Many factors including genetic, environmental, and acquired are involved in breast cancer development across various societies. Among all of these factors in families with a history of breast cancer throughout several generations, genetics, like predisposing genes to develop this disease, should be considered more. Early detection of mutation carriers in these genes, in turn, can play an import...
متن کاملPrevalence of BRCA1 and BRCA2 mutations in unselected breast cancer patients from medellín, Colombia
BACKGROUND Approximately 5% of all breast cancers can be attributed to a mutation in the BRCA1 or BRCA2 gene. The genetic component of breast cancer in Colombia has been, for the most part, studied on cases from the Bogota region. Five different founder mutations were in two studies of breast cancer patients in the Bogota region. It is important that the frequency of mutations be established am...

Background: Breast cancer is the most common female malignancy and the main cause of death in mid-aged women. Genetic germ line mutations in BRCAI/BRCA2 in Iranian women with breast or ovarian cancer have not been yet reported. Materials and methods: Clinical data, family history and blood samples were obtained from 83 females aged less than 45 years with primary breast cancer in order to su...

Background and purpose: Breast Cancer is one of the health problems in every population. The aim of this study was to determine the frequency of BRCA1 and BRCA2 common mutations in women whose mothers were diagnosed with breast cancer. Materials and methods: A case–control study was performed in 109 females (less than 40 years of age) who had mothers with breast cancer. For scanning of...
متن کاملPrevalence of BRCA2 mutations in a hospital based series of unselected breast cancer cases.
E pidemiological data suggest that 7% of breast cancer cases and 10% of ovarian cancer cases in the general population are attributable to one or more autosomal dominant susceptibility alleles. The breast and ovarian cancer susceptibility genes BRCA1 and BRCA2 were isolated in 1994 and 1995, 4 respectively, and since then, a large volume of literature attests to the involvement of these genes i...
