    Data source: Supplementary information, http://www.nature.com/ng/journal/v44/n11/full/ng.2440.html#supplementary-informationWe performed genomic mapping of a family with autosomal dominant nocturnal frontal lobe epilepsy (ADNFLE) and intellectual and psychiatric problems, identifying a disease-associated region on chromosome 9q34.3. Whole-exome sequencing identified a mutation in KCNT1, encoding a sodium-gated potassium channel subunit. KCNT1 mutations were identified in two additional families and a sporadic case with severe ADNFLE and psychiatric features. These findings implicate the sodium-gated potassium channel complex in ADNFLE and, more broadly, in the pathogenesis of focal epilepsies.Sarah E Heron, Katherine R Smith, Melanie Bahlo, Lino Nobili, Esther Kahana, Laura Licchetta, Karen L Oliver, Aziz Mazarib, Zaid Afawi, Amos Korczyn, Giuseppe Plazzi, Steven Petrou, Samuel F Berkovic, Ingrid E Scheffer, Leanne M Dibben

    Is photosensitive epilepsy less common in males due to variation in X chromosome photopigment genes?

    The definitive version is available at www.blackwell-synergy.comSummary: Photosensitive epilepsy is less frequent among males than females. Red is the most epileptogenic color. The X-linked red pigment gene contains the polymorphism Ser180Ala; the Ser180 allele increases red sensitivity. We hypothesized that the paucity of males with photosensitive epilepsy is explained by the distribution of this sex-linked allele, and predicted photosensitive males would have a low frequency of this allele. We genotyped 35 males with photosensitive epilepsy and 84 male controls. Allele frequencies did not differ between these groups. The hypothesis was not supported, so alternate reasons for the sex bias in photosensitive epilepsy must be sought.Isabella Taylor, Bree Hodgson, Ingrid E. Scheffer, John Mulley, Samuel F.
