case_images: DNA analysis of the involved patients. To search for mutations in KCNQ2 in the pedigree, 16 exons and adjacent short intronic sequences of the gene were amplified by polymerase chain reaction with DNA obtained from the affected individuals. Genetic study revealed a c.1342C>T (p. Arg448X) mutation located in the C-terminal segment of KCNQ2 in the family members with neonatal seizures (Ia, IIe, IIId).
