Ojective: In this study, we aimed to investigate if there is a relationship between mutations in SCN1A
(R1648H), SCN2A (GAL879-881QQQ), KCNQ2 (V182M) genes and epilepsy with generalized tonic-clonic
seizure (GTCS).
Materials and Methods: Seventy five patients with GTCS type epilepsy and 75 healthy subjects were
included in our study. DNA's of patients and controls were isolated and the interested regions of SCN1A, SCN2A, KCNQ2 genes were amplified by polymerase chain reaction (PCR). DNA sequence analysis was
applied to PCR products. The sequence analysis results were analyzed in MEGA (Molecular Evolutionary
Genetics Analysis) program. The findings were evaluated statistically.
Results: R1648H, GAL879-881QQQ, V182M mutations were not observed in the patient group and the
control group. R1648P variant, 134272 A>G polymorphism and 134347 G>A polymorphism were found
in SCN1A gene. 105649 G>A polymorphism was determined in SCN2A gene. 28704 T>G polymorphism
was found in KCNQ2 gene. The difference between variant and polymorphisms determined in patients
and control groups were not statistically significant (p>0.05).
Conclusion: SCN1A, SCN2A and KCNQ2 mutations may not be related to GTCS.
