Major genes for susceptibility to breast cancer include BRCA1 and BRCA2; these genes are characterized by high lifetime penetrance of cancer, with corresponding odds ratios (OR) in excess of ten [1]. Mutations in the CHEK2 gene confer a more modestly elevated risk of breast cancer (OR two to three) ...

Point mutation
A point mutation, or single base modification, is a type of mutation that causes a single nucleotide base change, insertion, or deletion of the genetic material, DNA or RNA. The term frameshift mutation indicates the addition or deletion of a base pair. A point mutant is an individual that is affected by a point mutation.Repeat induced point mutations are recurring point mutations, discussed below.
