Abstract
- The present study aimed at evaluating the potential contribution of Phosphatase and Tensin Homolog (PTEN) and its gene polymorphism (PTEN rs701848 T/C) in relation to Wingless/integrase-1 (Wnt) signaling in childhood epilepsy and the impact of antiepileptic medications on their serum levels. This study included 100 children with epilepsy (50 pharmacoresistant and 50 pharmacoresponsive) and 50 matched controls. All subjects had their genotypes for the PTEN rs701848T/C polymorphism assessed using TaqMan<superscript>TM</superscript> assays and real-time PCR. By using the sandwich ELISA technique, the blood concentrations of PTEN and Wnt3a were measured. Serum Wnt3a levels in epileptic patients were significantly higher than in the control group, p < 0.001. Children with epilepsy who received oxcarbazepine had considerably lower serum Wnt3a levels than those who didn't, p < 0.001.With an AUC of 0.71, the cutoff value for diagnosing epilepsy as serum Wnt3a > 6.2 ng/mL has a sensitivity of 55% and a specificity of 80%. When compared to controls, epileptic children had considerably more (TT) genotype and less (TC and CC) genotypes, p < 0.05 for all. Epileptic children had significantly higher (T) allele frequency than controls, p = 0.006 with OR (95%CI) = 1.962(1.206–3.192). Pharmacoresistant epileptic children had significantly higher (TT) genotype compared to pharmacoresponsive type (p = 0.020). We originally found a strong association between PTEN rs701848 T/C and childhood epilepsy, in particular pharmacoresistant type. Serum Wnt3a levels increased in epilepsy, but were not significantly different between different alleles of PTEN. In pharmaco-responsive children Wnt3a levels differed significantly between the different PTEN genotypes. Antiepileptics may affect Wnt3a levels. [ABSTRACT FROM AUTHOR]
