Evaluation of rs3102735 and rs2073617 Osteoprotegerin Gene Polymorphisms and the Risk of Childhood Acute lymphoblastic Leukemia in Zahedan Southeast Iran
Abstract
Introduction Osteoprotegerin (OPG), a soluble decoy receptor secreted by osteoblasts, binds RANK-L, preventing stimulation of osteoclastogenesis. In the present study we aimed to investigate the impact of OPG variants and susceptibility to childhood acute lymphocytic leukemia (ALL) in a sample of Iranian population. Methods This case-control study was done on 98 ALL and 124 healthy children. We genotyped the polymorphisms using tetra-primer ARMS-PCR (T-ARMS-PCR). Results Our findings showed that neither rs3102735 nor rs2073617 variants were associated with ALL in a sample of Iranian population. Concerning rs3102735 polymorphism, the age of ALL predispositions was significantly higher in TC+CC genotype than TT genotype (P=0.032). Furthermore, the CSF involvement was significantly higher in ALL subjects carrying TC+CC genotype (p=0.044). Conclusion We found no association between OPG (rs3102735, rs2073617) gene polymorphisms and risk of childhood ALL. Further studies with larger sample sizes and various ethnicities are necessary to verify our findings.
