We found genetic alterations in 17.3% of germinomas for KIT and 34.6% for RAS whereas Fukushima et al. [9] detected c-Kit mutations in 40% and RAS mutations in 20%, Wang et al. [14] 25% for KIT and 19% for RAS and recently Ichimura et al. [31] found c-Kit mutated in 40% and RAS mutated in 19% of germinomas. The gene discussed is KIT; the disease is germinoma.
