Founder mutations in BRCA1 and BRCA2 genes

open access: yesAnnals of Oncology, 2007
BRCA1 and BRCA2 germline mutations contribute to a significant number of familial and hereditary breast and/or ovarian cancers. The proportion of high-risk families with breast and/or ovarian cancer cases due to mutations in these tumor suppressor genes varies widely among populations.

Genetic predisposition to male breast cancer in Poland

open access: yesBMC Cancer, 2021
Background Breast cancer in men accounts for fewer than 1 % of all breast cancer cases diagnosed in men and women. Genes which predispose to male breast cancer include BRCA1 and BRCA2. The role of other genes is less clear.

Log odds of carrying an Ancestral Mutation in BRCA1 or BRCA2 for a defined personal and family history in an Ashkenazi Jewish woman (LAMBDA) [PDF]

open access: yes, 2003
INTRODUCTION: Ancestral mutations in BRCA1 and BRCA2 are common in people of Ashkenazi Jewish descent and are associated with a substantially increased risk of breast and ovarian cancer.

BRCA2 and Smad3 synergize in regulation of gene transcription [PDF]

open access: yesOncogene, 2002
Smad3 is an essential component in the intracellular signaling of transforming growth factor-beta (TGFbeta), which is a potent inhibitor of tumor cell proliferation. BRCA2 is a tumor suppressor involved in early onset of breast, ovarian and prostate cancer. Both Smad3 and BRCA2 possess transcription activation domains.

Presymptomatic breast cancer in Egypt: role of BRCA1 and BRCA2 tumor suppressor genes mutations detection

open access: yesJournal of Experimental & Clinical Cancer Research, 2010
Background Breast cancer is one of the most common diseases affecting women. Inherited susceptibility genes, BRCA1 and BRCA2, are considered in breast, ovarian and other common cancers etiology.

Overexpression of BRCA2 gene in sporadic breast tumours [PDF]

open access: yesOncogene, 1999
The breast cancer susceptibility gene BRCA2 is expressed in a wide range of tissues as an 11-kb mRNA transcript that encodes a 3418-amino acid protein involved in the response to DNA damage. To obtain better a molecular characterization of BRCA2 expression in sporadic breast cancer, we quantified BRCA2 mRNA by means of RT - PCR in a large series of ...

Common breast cancer susceptibility alleles are associated with tumour subtypes in BRCA1 and BRCA2 mutation carriers: results from the Consortium of Investigators of Modifiers of BRCA1/2 [PDF]

open access: yes, 2011
The associations of the 12 SNPs with risk for BRCA1 and BRCA2 carriers differ by ER-positive or ER-negative breast cancer status. The apparent differences in SNP associations between BRCA1 and BRCA2 carriers, and non-carriers, may be explicable by ...

Clues to the Function of the Tumour Susceptibility Gene BRCA2 [PDF]

open access: yesDisease Markers, 1998
The breast cancer susceptibility gene BRCA2 was isolated in 1995. BRCA2 is a large gene comprising 10,254 nucleotides and 26 coding exons. Neither the nucleotide nor the predicted protein sequences (comprising 3,418 amino acids) have provided substantial clues about its function. As a result, researchers have been trying to elucidate the function using

BRCA2 and Other DDR Genes in Prostate Cancer [PDF]

open access: yesCancers, 2019
Germline and somatic aberrations in DNA damage repair (DDR) genes are more prevalent in prostate cancer than previously recognized, with BRCA2 as the most commonly altered gene. Germline mutations in BRCA2 have been linked to poor prognosis when patients are managed under the protocols currently approved for prostate cancer.
