ResumoIntroduction Alternating hemiplegia of childhood (AHC) is a rare disorder mainly characterized by attacks of hemiplegia and mental retardation. It has been often associated with migraine. The CACNA1A gene on chromosome 19 is involved in familial hemiplegic migraine and other episodic cerebral disorders, but also with progressive neuronal damage. Methods We performed mutation analysis in this gene in four AHC patients, using single strand conformation polymorphism analysis. Results We found nine polymorphisms, but no mutations in any of the 47 exons. Conclusions Other cerebral ion channel genes remain candidate genes for AHC.
