IL5 and non-Hodgkin lymphoma: A study conducted by Chen and colleagues demonstrated a role of the T-allele of rs2069812 in increasing the risk of developing Non-Hodgkin lymphoma (NHL) [18], and another work showed the influence of this specific SNP in causing a decrease in IL-5 serum concentration, modifying Th1/Th2 response in terms of susceptibility for NHL [19].
