For example, (i) variations in the MAPT (encoding for microtubule-associated protein tau), TUBB2A, GSK3β, CYP2C8, and CYP3A4 polymorphisms have been associated with paclitaxel-induced neuropathy [19]; (ii) NaV channels polymorphisms have been associated with oxaliplatin-induced CIPN [6]; and (iii) Actin gamma 1 (ACTG1) and Capping actin protein, Gelsolin-like (CAPG) polymorphisms have been linked to vincristine-induced neuropathy [19]. The gene discussed is CYP3A4; the disease is neuropathy.
