Abstract:
Objective To investigate the virulence gene and mutation features in the Chinese patients with autosomal dominant noctumal frontal lobe epilepsy(ADNFLE) by using the direct sequencing(DS) PCR products with all the exons of CHRNA4 in 6 ADNFLE families,and to interpret the molecular pathogenesis in Chinese patients affected by ADNFLE.Methods Six ADNFLE families were collected,included 66 people and 24 patients with ADNFLE,and 200 healthy volunteers were selected as control group.The genomic DNA was extracted.The exons 1-6 in CHRNA4 were amplified by the PCR.The amplified products were sequenced and analyzed.All data were analyzed with SPSS 13.0 software.Results There were 4 base substitutions in exon 5,and they were c.909T ＞ G,c.1440G ＞ T,c.1458T ＞ C and c.942C ＞ T.All those base substitutions were synonymous.The first three were homozygosis substitutions,but the last one was heterozygosis substitutions.Conclusions The hot spot mutations of CHRNA4 which have been reported were not detected.Whether or not there is a correlation between ADNFLE and this substitution need to be identified by study with
