Rapley et al., Turnbull et al. and Kanetsky et al. revealed other loci associated with testicular cancer related to single nucleotide polymorphism changes affecting KITLG (ligand for the tyrosine kinase KIT; OR = 2.69), SPRY4 (inhibitor of mitogen-activated protein kinase downstream of KITLG-KIT; OR = 1.37), BAK1 (similarly to the previous one; OR = 1.50), DMRT1 (involved in gender determination; OR = 1.37), and TERT and ATF7IP (involved in telomere maintenance; OR = 1.54 and OR = 1.27, respectively) [136,137,138]. This evidence concerns the gene KITLG and testicular cancer.
