Several authors have analyzed the association of the ERBB2 polymorphisms rs2643194 (c.−18+1614 C>T), rs2517951 (c.−18+1663 C>T), rs2643195 (c.−18+1684 A>G), rs2934971 (c.−18+3073 G>T), and rs1058808 (c.3418 C>G) with some types of cancer (5, –11); however, these have not been analyzed in patients with GC. The gene discussed is ERBB2; the disease is cancer.
