MMP9 and B-cell chronic lymphocytic leukemia: Consistent with findings in the U.S. study, homozygosity for the MMP9 rs3918241 variant resulted in an elevated OR for NHL approaching significance (US: OR = 1.7, 95% CI = 0.95–3.0, p = 7.4×10−2; Germany: OR = 2.5, 95% CI = 0.80–8.1; p = 1.0×10−1), however, there was no increased risk of CLL with the variant allele as found in the U.S. study.
