CD38 gene polymorphism and risk of chronic lymphocytic leukemia

rs6449182 CD38 gene polymorphism was determined by polymerase chain reaction with restriction of products in 328 chronic lymphocytic leukemia (CLL) patients and 271 age- and sex-matched controls. An association between GG genotype and CLL risk was found in the whole group of patients (OR=2.12; p=0.009) and in patients with unmutated immunoglobulin heavy chain variable genes (OR=2.17; p=0.011) comparing to the controls. In the subgroup of 174 controls with evaluated lipids the genotype distributions in CLL patients and dyslipidemic controls were similar. An association between GG genotype and CLL risk was significant compared to controls without lipids' abnormalities (OR=3.92; p=0.006).
