Abstract
The findings of dysmorphic syndromes associated with X-linked chromosomopathy and epilepsy are infrequent. It is a case of genetic alteration in a male patient, with X-linked microduplication MECP2 and familiar history of a sibling with similar phenotype, which compares the maternal blood line of different parents. X-linked dysmorphic syndrome MECP2 (methyl-CpG2 binding protein), causing severe mental retardation, epileptic encephalopathy and recurrent infections of the respiratory tract and consecutively also have epilepsy resistant to pharmacological management.
