Abstract
Introduction: Febrile seizures (FS) are the most common neurological
disease in childhood. The etiology of FS is the subject of numerous studies
including studies regarding genetic predisposition. Aim: The aim of
the study was to analyze the association of TRPV1 rs222747 and
KCC2 rs2297201 gene polymorphisms with the occurrence of
FS. Materials and Methods: The study included 112 patients
diagnosed with FS classified as simple febrile seizures (SFS) or complex febrile
seizures (CFS). We analyzed selected polymorphisms of KCC2 and
TRPV1 genes using the Real-time PCR method.
Results: The CT and TT genotypes of the rs2297201 polymorphism
of the KCC2 gene are significantly more common in the group of
children with FS than the control group (p = .002) as well as
the allele T of this polymorphism (p = .045). Additionally,
genotypes CT and TT of the rs2297201 polymorphism of the KCC2
gene were more frequent in the group of children with CFS compared to the
control group (p < .001). Different genotypes and alleles of
the rs222747 TRPV1 gene polymorphism were not associated with
the occurrence of febrile seizures or epilepsy, nor were associated with the
occurrence of a particular type of febrile seizure (p = .252).
Conclusion: These results indicate that the CT and TT
genotypes, as well as the T allele of rs2297201 polymorphism of the
KCC2 gene, could be a predisposing factor for the FS, as
well as the occurrence of CFS.
