FLT3LG and non-Hodgkin lymphoma: For LEP −2548G>A, an increased risk for NHL was observed among carriers of the LEP −2548GA (OR=1.3, 95% CI 1.0–1.7, P=0.03) and LEP −2548AA genotypes (OR=1.4, 95% CI 1.0–1.9, P=0.04), particularly for FL (LEP −2548GA: OR=1.6, 95% CI 1.1–2.3, P=0.01; LEP −2548AA: OR=1.4, 95% CI 0.9–2.3, P=0.12) when compared to LEP −2548GG carriers.
