Functional TET2 gene polymorphisms increase the risk of neuroblastoma in Chinese children.
Lin et al., IUBMB Life 2023
DOI: 10.1002/iub.2791
What’s New: The study investigates the association between TET2 gene polymorphisms and neuroblastoma risk, which has not been previously elucidated. It identifies specific polymorphisms (rs10007915 G > C and rs7670522 A > C) that significantly increase the risk of neuroblastoma.
Importance: This research highlights the role of TET2 gene polymorphisms in neuroblastoma susceptibility, providing potential biomarkers for risk assessment and insights into the disease’s etiology.
Contribution to Literature: The study adds to the understanding of epigenetic regulation in cancer by linking TET2 polymorphisms to neuroblastoma risk and prognosis. It also correlates these polymorphisms with TET2 and PPA2 gene expression levels.
Results Summary:
– TET2 polymorphisms (rs10007915 G > C and rs7670522 A > C) were found to significantly increase neuroblastoma risk in a study of 402 patients and 473 controls.
– Stratification analysis revealed stronger associations in specific subgroups.
– These polymorphisms are associated with reduced TET2 mRNA expression.
– Lower TET2 expression correlates with higher neuroblastoma risk, MYCN amplification, and poorer prognosis.
– The same polymorphisms are linked to increased expression of inorganic pyrophosphatase 2 (PPA2) mRNA, which is also associated with higher risk and poor prognosis in neuroblastoma.
Conclusion: The identified TET2 polymorphisms are significant markers of neuroblastoma susceptibility, warranting further investigation into their mechanisms.
