Epilepsy is reported to occur in 10 to 20% of individuals with fragile X syndrome (FXS). A frequent seizure/EEG pattern in FXS appears to resemble that of benign focal epilepsy of childhood (BFEC, benign rolandic epilepsy). To evaluate seizure frequency and type in a Chicago FXS cohort, data regarding potential seizure history were reviewed for 136 individuals with FXS (age range 2 to 51 years: 113 males and 23 females). Seizures occurred in 15 males (13.3%) and one female (4.8%): of these, 12 had partial seizures. EEG findings were available for 35 individuals (13 of 16 with seizures and 22 of 120 without seizures) and showed an epileptiform abnormality in 10 (77%) individuals with seizures and five (23%) individuals without seizures--the most common epileptiform pattern being centrotemporal spikes. Seizures were easily controlled in 14 of the 16 individuals with seizures. Many individuals, including all with centrotemporal spikes, had remission of seizures in childhood. The most common seizure syndrome resembled BFEC and this pattern had the best prognosis for epilepsy remission. Deficiency of FMRP (fragile X mental retardation protein) appears to lead to increased neuronal excitability and susceptibility to epilepsy, but particularly seems to facilitate mechanisms leading to the BFEC pattern.

Autism is a strong genetic disorder, with an estimated heritability greater than 90%. Nonetheless, its specific genetic aetiology remains largely unknown. Autism is associated with epilepsy in early childhood and epilepsy occurs in 10-30% of individuals with autism. Here we report the case of a woman affected by a severe epileptic disorder with an onset at 14 years old. She is affected by a cryptogenetic focal epilepsy with complex partial (psychomotor) and secondarily generalized tonic-clonic seizures, which are drug resistant. The woman is married to a healthy man and has six children: two girls are healthy, a girl and two boys are affected by autism while one boy shows partial seizures. The three children with autism show moderate mental retardation and an EEG with no epileptiform alterations. The child with epileptic seizures shows an asymmetric EEG that is not necessarily pathological. In this family, no chromosomal rearrangements were detected by means of classical cytogenetic analyses. The presence of FRAXA alterations and of microdeletions of the 15q11-q13 chromosome region were also excluded. A genome-wide linkage analysis using microsatellite markers revealed several chromosome regions as possible susceptibility loci.
