Association of LIN28B Gene Polymorphisms (rs221634, rs221635, rs314276, rs9404590, and rs12194974) with Non-Hodgkin Lymphoma Susceptibility and Clinical/Pathological Features.

BACKGROUND AND AIM

Lymphoma is a common hematopoietic cancer.  It has been proposed that LIN28B gene and its variations may have function in cancer progression and metastasis. Therefore, the purpose of this investigation has been to examine the correlation among LIN28B gene polymorphisms (such as rs221634 A>T, rs221635 T> C, rs314276 C>A, rs9404590 T>G, and rs12194974 G>A) as well as the risk of NHL in an Iranian sample.

MATERIALS AND METHODS

In the current case-control research, 175 individuals with Non-Hodgkin Lymphoma along with 175 normal controls participated; polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) methodology has been utilized to the genotype samples.

RESULTS

Our data demonstrated that rs12194974 and the rs221635 variants have been correlated with higher NHL risk, while rs221634 and rs314276 variants were correlated with lower risk of NHL (P≤0.05). In addition, we detected an association between rs221634 and treatment with R-CHOP. No substantial correlation has discovered among rs9404590 polymorphism and NHL in any inheritance models (P≥0.05).

CONCLUSION

This was the first investigation evaluating the correlation among LIN28B gene polymorphisms as well as the occurrence of NLH. Further studies in different ethnic populations and large-scale sample size are needed to support results.
