A syndrome is characterized by major seizures, dysmorphic features (round face, bulbous nose, wide mouth, prominent philtrum), pes planus, psychomotor retardation and obesity. It has been described in five children (three boys and two girls, one of whom died in infancy) from two unrelated Mexican families. This condition is likely to be transmitted as an autosomal recessive trait. The disease is MONDO_0016290 (Hernández-Aguirre Negrete syndrome). Also known as: intellectual disability-epilepsy-bulbous nose syndrome.
