We report on a 2-year-old boy with facial dysmorphism, multiple lentigines, and hypertrophic cardiomyopathy. Mutation analyses of the patient and his mother revealed a Y279G mutation in exon 7 of the PTPN11 gene. The presence of LEOPARD syndrome was confirmed by a genetic study and clinical phenotypes. Since age 18 months, the patient had manifested frequent seizures that were poorly controlled by multiple anticonvulsants. Neurologic examinations indicated severe developmental delay and sensorineural deafness. Brain imaging demonstrated open-lip schizencephaly in the right frontoparietal area. Central nervous system anomalies are rarely reported in this disease. To the best of our knowledge, this is the first report of LEOPARD syndrome with associated schizencephaly. Psychomotor retardation is not uncommon in LEOPARD syndrome. We advocate brain-imaging studies of patients with LEOPARD syndrome and neurologic abnormalities such as developmental delay or epilepsy.
