Mutation screening of the RNF8, UBC13and MMS2genes in Northern Finnish breast cancer families
Abstract Background Currently known susceptibility genes such as BRCA1 and BRCA2 explain less than 25% of familial aggregation of breast cancer, which suggests the involvement of additional susceptibility genes. RNF8, UBC13 and MMS2 are involved in the DNA damage response pathway and play important...
