Aim: This study aimed to determinant association between rs76189946 polymorphism of EGF gene and risk of colorectal cancer in an Iranian population.

Background: Colorectal cancer (CRC) is the third most prevalent cancer in both genders worldwide. The determination of genetic variation becomes a new way to etiology of colorectal cancer. Epidermal growth factor (EGF) is a mitogen that plays an important role in cell growth and tumourigenesis, this protein acts by binding its receptor, EGFR.

Patients And Methods: DNA samples taken from totally 125 CRC patients and healthy controls were amplified by polymerase chain reaction (PCR) for the rs76189946 polymorphism. Genotypes were analyzed using restriction fragment length polymorphism (RFLP). Finally to confirm the RFLP procedure, 20 of the PCR products were sequenced using the ABI PRISM 3130xl Genetic Analyzer and chain termination method (Applied Biosystems, Carlsbad, CA).

Results: Genotype distribution and allele frequency was similar in CRC patients and controls individuals. We expect observe C and G allele in both groups but only was found C allele.

Conclusion: In this study for first time we identified genetic distribution of exonic rs76189946 polymorphism in EGF gene both CRC patients and healthy controls. These results suggest there wasn't association between EGF polymorphism rs76189946 and risk of colorectal cancer in an Iranian population.
