LIN28A gene polymorphisms confer Wilms tumour susceptibility: A four-centre case-control study

Area of Science:

• Genetics
• Pediatric Oncology
• Molecular Biology

Background:

• Wilms tumour is a common childhood kidney cancer.
• LIN28A gene overexpression is implicated in various cancers.
• The role of LIN28A in Wilms tumour development requires further investigation.

Purpose of the Study:

• To investigate the association between LIN28A gene polymorphisms and Wilms tumour risk.
• To identify specific single nucleotide polymorphisms (SNPs) associated with increased Wilms tumour susceptibility.

Main Methods:

• Genotyping of four LIN28A polymorphisms (rs3811464, rs3811463, rs34787247, rs11247957) in 355 Wilms tumour patients and 1070 healthy controls.
• Statistical analysis including overall, combination, and stratified analyses.
• Expression quantitative trait locus (eQTL) analysis to assess allele-specific gene expression.

Main Results:

• SNPs rs3811463 T>C and rs34787247 G>A were significantly associated with increased Wilms tumour risk.
• Carrying one or multiple risk genotypes correlated with a higher likelihood of developing Wilms tumour (ORs 1.58 and 1.56).
• The rs3811463 C allele was linked to increased LIN28A gene transcripts, suggesting a functional impact.

Conclusions:

• LIN28A gene polymorphisms, particularly rs3811463 and rs34787247, may contribute to an increased predisposition to Wilms tumour.
• These genetic variations could serve as potential biomarkers for Wilms tumour risk assessment.
• Further research is warranted to elucidate the precise mechanisms underlying LIN28A's role in Wilms tumour pathogenesis.
