Prevalence of HIMAL in adult patients with 22q11.2 deletion syndrome from this study compared to the reported prevalence in studies of other conditions. Legend: Prevalence of HIMAL in the following populations: Control: this is represented here (first bar) as the mean of the values from three independent studies: 0/497 controls18, 5/5020 and 19/100 controls19. General Epilepsy Population: out of 527 patients with epilepsy (multiple causes) 32 (5%) had HIMAL17. Patients with Prolonged Febrile Seizures: out of 107 children enrolled, 12% of them had HIMAL21. Patients with Other Brain Developmental Abnormalities: The presence of HIMAL in patients with other hemispheric developmental disorders was 22%17. No genetic tests results were available in the above four categories of patients. Patients with Chromosome 22q11.2 Deletion: without screening for the presence of seizures 9 out of 14 had HIMAL. Patients with Chromosome 22q11.2 Deletion without Epilepsy: 6 out of 10 patients in this group had HIMAL. Patients with Chromosome 22q11.2 Deletion with epilepsy: 3 out of 4 patients in this group had HIMAL.
