SK3 Gene Polymorphism Is Associated with Taxane Neurotoxicity and Cell Calcium Homeostasis.

Taxane-induced peripheral neuropathy is a common side effect induced by anticancer agents, and no drug capable of preventing its occurrence or ameliorating its long-term course has been identified. The physiology of taxane neuropathy is not clear, and diverse mechanisms have been suggested, with ion channels regulating Ca homeostasis appearing good candidates. The calcium-activated potassium channel SK3 is encoded by the gene, which is characterized by a length polymorphism due to variable number of CAG repeats.
