简要总结
Febrile seizures (FS) are the most common neurological disorder in chilhood. The etiology of FN is still the subject of numerous studies and it is known that it can depend on genetic predisposition.
详细描述
Febrile seizures (FS) are the most common neurological disorder in chilhood. It is precisely because of the high incidence of the disease, the age that includes the tendency of repetition, represent a particular challenge in pediatric practice.
FS, as defined by the American Academy of Pediatrics (AAP), are " seizure occurring in febrile children between the ages of 6 and 60 months who do not have an intracranial infection, metabolic disturbance, or history of afebrile seizures ".
Simple febrile seizure is defined as a short (<15 min) generalized seizure, not repeat within 24 h, that occurs during a febrile illness not resulting from an acute disease of the nervous system in a child aged between 6 months and 5 years, with no neurologic deficits and no previous afebrile seizures. Complex febrile seizures are a focal, or generalized and prolonged seizure, of a duration of greater than 15 min, recurring more than once in 24 h, and/or associated with postictal neurologic abnormalities, more frequently a postictal palsy (Todd's palsy), or with previous neurologic deficits.
The etiology of FN is still the subject of numerous studies and it is known that it can depend on genetic predisposition.
Animal studies have shown that mice without the KCC2 gene have frequent generalized seizures, while those with heterozygous deletion of the KCC2 gene have a reduced threshold for seizure onset. In the human population, mutations of this gene have been reported in children with FN as well as in children with epilepsy. There is no examined an association between polymorphism rs2297201 KCC2 gene and FS.

结局指标
主要结局
Detection of the polymorphism in the TRPV1 gene polymorphisms
时间窗: 2 weeks
The detection of the polymorphism in the TRPV1 gene will be done by the PCR Real time method: During PCR ampification, in addition to primers, an allele of specific oligonucleotide probes is used, which at the 5 'end is labeled with specific fluorescent dye (Reporter dye, eg VIC and FAM), while at the 3' position there is a quencher, which is the role of blocking fluorescence emissions.The fluorescence intensity increases during each cycle and allows us to monitor dynamic reactions in real time.After the final PCR reaction, increasing the fluorescence of the dyes is displayed on the heterozygosity of the test allele. Fluorescence coupling of only one color indicates a homozygous state.VIC dye corresponds to allele C, and FAM dye to allele G.
