WDR87 and cancer: While we did not observe driver mutations in KIF4A and WDR62 that have been observed in metastatic prostate cancer [55], we did observe mutations in KIF5C, KIF7, KIF14, KIF18A, KIF20B, and KIF22 as well as in WDR17, WDR78, and WDR87, suggesting that other members of these families may also serve as cancer drivers.
