ABSTRACT
OBJECTIVE: To look for gene polymorphism loci influencing valproic acid interindividual differences, thus to provide support for treating epilepsy patients with valproic acid. METHODS: Through the KEGG Database, genes and their loci influencing valproic acid pharmacokinetics and pharmacodynamics were inquired from the perspective of pathway: literature was searched about valproic acid-related gene polymorphisms: the FastSNP was used to estimate the risk of the genes found from KEGG Database and literature: the dbSNP database was used to find the distribution of the gene loci with higher risk in Chinese and then to select the loci for the experimental study. RESULTS: The related gene inquired from the perspective of pathway were ABAT, CACNA1I, CACNA1H, CACNA1G, CDY2B, CDY1B, CDY1, CDY2A, CYP2C9, and CYP3A4. Through literature search and bioinformatics methods, 29 influencing loci on valproic acid were identified, including rs1641021, rs1731017, and rs1057910, and so on. CONCLUSION: From this bioinformatics research, the gene polymorphism loci affecting valproic acid interindividual difference are successfully screened. This study provides genetics basis for individual treatments of epileptic patients.
