Abstract: A method for determining the sensitivity of a patient with cancer to receptor tyrosine kinase inhibitor therapy is provided. The method comprising screening a nucleic acid sample to determine the identity of at least one single nucleotide polymorphism (SNP) genotype selected from the group consisting of rs1933437, rs1045642, rs1128503, rs2032582 and rs2231142 and any combination thereof; and determining the sensitivity of a patient with renal cancer to receptor tyrosine kinase inhibitor therapy based on the identity of the SNP genotype. The sensitivity is selected from one or more of neutropenia, diarrhea, tumor response, early toxicity-necessitated treatment termination, overall survival and progression-free survival.
