MEDICAL SCIENCES. For the article “A missense mutation of the Na⁺ channel α_II subunit gene Na_v1.2 in a patient with febrile and afebrile seizures causes channel dysfunction” by Takashi Sugawara, Yuji Tsurubuchi, Kishan Lal Agarwala, Masatoshi Ito, Goryu Fukuma, Emi Mazaki-Miyazaki, Hiroshi Nagafuji, Masaharu Noda, Keiji Imoto, Kazumaru Wada, Akihisa Mitsudome, Sunao Kaneko, Mauricio Montal, Keiichi Nagata, Shinichi Hirose, and Kazuhiro Yamakawa, which appeared in number 11, May 22, 2001, of Proc. Natl. Acad. Sci. USA (98, 6384–6389), the authors wish to correct the position given for the amino acid that was mutated in the patient. The mutation “R187W” should be “R188W.”
