Abstract:
DNA damage induced by high dose melphalan and autologous transplantation is repaired by the nucleotide excision repair (NER) and base excision repair (BER) pathways. We evaluated the association between single nucleotide polymorphisms (SNPs) (n=311) in the NER and BER pathways and disease progression in 695 multiple myeloma patients who underwent autologous transplantation. None of the SNPs were associated with disease progression. Pathway based analyses showed that the NER pathway had a borderline association with disease progression (p=0.09). These findings suggest that common variation in the NER and BER pathways do not substantially influence disease progression in multiple myeloma patients.

Nucleotide Excision Repair
Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...
