Custodio et al. [71] discovered that cyclin H (CCNH) rs2230641 C/C and the ATP-binding cassette subfamily G, member 2 (ABCG2) rs3114018 A/A, were associated with a higher risk of severe oxaliplatin-induced peripheral neuropathy in patients with stage II and III CRC. Here, CCNH is linked to peripheral neuropathy.
