Etiology of familial breast cancer with undetected BRCA1 and BRCA2 mutations: clinical implications.
Athens, Greece. In Cell Oncol (dordr), Feb 2014
RESULTS: After excluding BRCA1 and BRCA2 mutations, factors proposed to contribute to familial breast cancer include: chance clustering of apparently sporadic cases, shared lifestyle, monogenic inheritance, i.e., dominant gene mutations associated with a high risk (TP53, PTEN, STK11), dominant gene mutations associated with a relatively low risk (ATM, BRIP1, RLB2), recessive gene mutations associated with horizontal inheritance patterns (sister-sister), and polygenic inheritance where susceptibility to familial breast cancer is thought to be conferred by a large number of low risk alleles.
Breast cancer genes: beyond BRCA1 and BRCA2.
Spain. In Front Biosci, 2012
Moreover, a combination of family-based and population-based approaches indicated that genes involved in DNA repair, such as CHEK2, ATM, BRIP1 (FANCJ), PALB2 (FANCN) and RAD51C (FANCO), are associated with moderate BC risk.
Mutations in BRIP1 confer high risk of ovarian cancer.
Reykjavík, Iceland. In Nat Genet, 2011
We discovered a rare (0.41% allelic frequency) frameshift mutation, c.2040_2041insTT, in the BRIP1 (FANCJ) gene that confers an increase in ovarian cancer risk (odds ratio (OR) = 8.13, P = 2.8 × 10(-14)).
Structure of the DNA repair helicase XPD.
Saint Andrews, United Kingdom. In Cell, 2008
The XPD helicase (Rad3 in Saccharomyces cerevisiae) is a component of transcription factor IIH (TFIIH), which functions in transcription initiation and Nucleotide Excision Repair in eukaryotes, catalyzing DNA duplex opening localized to the transcription start site or site of DNA damage, respectively.
