rs16941
0.020 GeneticVariation BEFREE A significant increase in the cancer risk associated either with harboring one additional putative high-risk NHEJ genotype or with the joint effect of having reproductive risk factors (reflected by an interval of > or =12 years between menarche and first full-term pregnancy) and a higher number of high-risk genotypes of the NHEJ genes was only seen in women with at least one variant BRCA1 allele (i.e., the Glu/Gly or Gly/Gly forms of BRCA1 Glu(1038)Gly); and (b) a phenotype-based study measuring in vitro and in vivo NHEJ capacity showed that the precise end-joining capacity was different in breast cancer cell lines with different BRCA1 statuses being higher in BRCA1-expressing MCF-7 cells than in HCC1937 cells (defective BRCA1 expression). 15256476
