Summary

This study will examine DNA from Gastrointestinal Tract of cancer patients treated with oxaliplatin to look for a variation (mutation) of the ABCG2 gene that may lead to drug-induced peripheral neuropathy in certain patients. The DNA will be extracted from patients' blood samples and are analyzed for the ABCG2 single nucleotide polymorphism (G34A - rs2231137 and A/A -rs3114018 genotypes) and correlated with peripheral neuropathy grades.

Detailed description

Pharmacogenetic analysis/genotyping : Genotyping is conducted via High Resolution Melting (HRM) TECHNIQUE, To confirm the genotyping results, the Polymerase chain reaction (PCR) product of the samples will be examine via direct sequencing using 3500 Genetic analyzer from ThermoFisher (applied biosystem) at two ABCG2 loci using the following PCR primers: 1-ABCG2 G34A - rs2231137 Forward : 5'-TGC AAT CTC ATT TAT CTG GAC TA-'3 Reverse : 5'-AAT GCC TTC AGG TCA TTG GA-'3 -Annealing temp :57 -Product size : 163 2- ABCG2 A/A - rs3114018 Forward : 5'- TGATGTTCCTTCAGCCACTG-'3 Reverse : 5'-TTGTGGAAACCTCACAAAAGTG-'3 \- Annealing temp : 59 - Product size : 124
