Febrile seizures (FS) are common in children, and the incidence is 2-5% before the age of 5 years. A four-generation Chinese family with autosomal dominant febrile seizure and epilepsy was studied by genome-wide linkage analysis. Significant linkage was identified with markers on chromosome 3q26.2-26.33 with a maximum pairwise LOD score of >3.00. Fine mapping defined the new genetic locus within a 10.7-Mb region between markers D3S3656 and D3S1232. A maximum multipoint LOD score of 5.27 was detected at marker D3S1565. A previously reported CLCN2 gene for epilepsy was excluded as the disease-causing gene in the family by mutational analysis of all exons and exon-intron boundaries of CLCN2 and by haplotype analysis. Mutation analysis of KCNMB2 and KCNMB3, which were two potassium-channel genes in this linkage region, did not reveal a disease causing mutation. Our results identified another novel locus on chromosome 3q26.2-26.33, and future studies of the candidate genes at the locus will identify a new gene for combined FS and idiopathic epilepsies.
