There is a case report of a t(4;8)(p15.2;p23.2) translocation interrupting the coding sequence of CSMD1 segregating with juvenile myoclonic epilepsy, self‐limited photosensitive occipital epilepsy, and migraine with aura in a family.[74] An 8p23‐p21 deletion encompassing CSMD1 was found in a Saudi Arabian family with autosomal dominant epilepsy and intellectual disability.[75]. Here, CSMD1 is linked to juvenile myoclonic epilepsy.
