Genetic variants of CYP4F12 gene are associated with glioma susceptibility

Glioma is a common and fatal primary malignant tumor of the central nervous system, and its prognosis is poor. To determine the susceptibility markers of gliomas in Chinese population we conducted a genome-wide association study (GWAS) of glioma in the Han Chinese population, with a total of 485 glioma cases and 485 controls. Genotyping was conducted using the Applied Biosystems Axiom Precision Medicine Diversity Array. Besides, we carried out imputation using IMPUTE 2.0 software, and the 1000 Genomes Phase 3 was used as the reference panel. The logistic regression model was used to analyze the association of each SNP with glioma risk, assuming an additive genetic model, which was implemented in PLINK version 1.9. Odds ratio (OR) and 95% confidence interval (CI) were estimated from logistic regression analysis with adjustment for age and gender. The results revealed that the SNP (rs688755) in the exon region of CYP4F12 at 19p13.12 reached genome-wide significance associated with gliomas (P = 2.35 x 10(-8), OR = 3.55, 95% CI = 2.20-5.74). Our findings provide deeper insight into the genetic contribution to glioma in different populations.

Automated summary

This study identified a SNP (rs688755) in the exon region of CYP4F12 at 19p13.12 as significantly associated with gliomas in the Han Chinese population through a genome-wide association study. The findings provide valuable insight into the genetic contribution to glioma in different populations, with implications for further research and potential clinical applications.
