CXCL12 G801A polymorphism and susceptibility to glioma: a case‑control study

Area of Science:

• Genetics
• Oncology
• Molecular Biology

Background:

• The CXCL12 G801A polymorphism is associated with cancer risk.
• The CXCL12/CXCR4 pathway influences glioma progression (proliferation, metastasis, invasion).
• The role of the CXCL12 G801A polymorphism in glioma risk among Chinese populations is unclear.

Purpose of the Study:

• To investigate the association between the CXCL12 G801A polymorphism and glioma susceptibility in Chinese individuals.
• To explore the relationship between this polymorphism and glioma's clinicopathological characteristics.

Main Methods:

• Case-control study involving 750 glioma patients and 750 healthy controls.
• Restriction fragment length polymorphism (RFLP) analysis to determine genotype frequencies.
• Statistical analysis to assess associations with glioma risk, grade, and histology.

Main Results:

• Glioma patients exhibited a significantly higher frequency of the CXCL12-3' A/A genotype compared to healthy controls (P = 0.039).
• High-grade glioma patients showed a significantly higher frequency of the CXCL12-3' A/A genotype versus low-grade patients (P = 0.019).
• Stage IV glioma patients had a significantly higher frequency of the CXCL12-3' A/A genotype (P = 0.037).

Conclusions:

• The CXCL12 G801A polymorphism is a risk factor for glioma development in a portion of the Han Chinese population.
• The CXCL12-3' A/A genotype is specifically associated with increased glioma susceptibility and higher tumor grades.
