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...
