Refractory Photosensitive Epilepsy Associated with a Complex Rearrangement of Chromosome 2

Abstract

We describe the relevant clinical and therapeutic parameters in a single patient with a complex chromosome 2 abnormality presenting with refractory myoclonic photosensitive epilepsy. FISH technology using yeast artificial chromosomes (YACs) was employed to determine breakage points, microdeletions and inversions on the affected chromosome. In this patient with refractory photosensitive epilepsy, 12 breakpoints and one small inversion were identified on the abnormal chromosome 2. Our data can be used in further genetic studies on the exact location and identification of photosensitivity genes.

Key words
