Do we consider Andermann syndrome in infants with agenesis of corpus callosum.

Andermann syndrome is characterized by agenesis of corpus callosum, anterior horn cell disease, a mixed sensory and motor neuropathy, and facial dysmorphism, and is inherited as an autosomal recessive trait. A 7-month-old boy was admitted with developmental retardation. Head control was not gained and he could not sit. He had high arched palate, elongated facies and large angle of the mandible, which were compatible with the Andermann syndrome. Moderate hypotonicity and absent tendon reflexes were also noted. Serum creatine kinase level was normal. Magnetic resonance imaging of the brain showed agenesis of the corpus callosum. Electromyographic examination revealed the presence of both sensory and motor neuropathy. The patient was diagnosed as having the Andermann syndrome according to the clinical and laboratory findings and he is reported due to rare presentation.
