There is no agreement on which channel is involved in oxaliplatin neurotoxicity, most investigators favouring voltage-gated sodium channels. However, the small conductance Ca(++) activated K(+) channels, encoded by the SK1-3 genes, are also involved in membrane excitability, playing a role in after-hyperpolarization at the motor nerve terminal. As the SK3 gene is characterized in Caucasians by a highly polymorphic CAG motif within the exon 1, we hypothesize that SK3 gene polymorphism may influence the development of acute nerve hyperexcitability in oxaliplatin-treated patients.
