XYLT2 and cutaneous melanoma: In cutaneous melanoma, the direct association of the ERBB family with other genes (SOS, NF1, PDGFRA, FGFR1, RASA1, ROS1, FGFR3, RAC1, PTPN11, NTRK2, FLT3, FGFR2, ERRFI1, and RIT1) had not been reported, and so the relationship between ERBB family and these genes remains to be further studied and determined.
