Two specific areas in chromosome 7 and chromosome 16 have been associated with photosensitivity, an epilepsy-related trait, by a team of European scientists in the January issue of Human Molecular Genetics. Photosensitivity or photoparoxysmal response (PPR) is associated with the most common epilepsy of genetic origin –Idiopathic Generalised Epilepsy (IGE) - and comprehension of the genetics behind it is important to a better understanding of IGE and epilepsy in general.
