A large meta-analysis of more than 114,000 people found that certain genetic variations in the IL-10 gene are linked to a small increase in the risk of non-Hodgkin lymphoma (NHL). The study combined data from 53,864 NHL patients and 60,448 healthy controls. Researchers looked at several single nucleotide polymorphisms (SNPs) in the IL-10 gene, which is involved in immune regulation.
They found that the rs1800890 variant was associated with a 6% to 12% higher risk of NHL, depending on the genetic model. The rs1800896 variant was linked to a 7% to 8% higher risk. These results were statistically significant. However, the increases are modest, and the findings were not consistent across all analyses.
One variant, rs1800871, showed a nominally significant protective effect in Caucasians, meaning it was linked to a 13% lower risk. But the researchers caution that this finding was only borderline significant and may not hold up in further studies.
It is important to note that this study shows an association, not cause and effect. The results are based on observational data and have limitations, including inconsistent findings across different populations. Readers should not change their health practices based on this single analysis. Anyone concerned about NHL risk should talk to their doctor.
