Aicardi Syndrome

Dr. Elliott Sherr and his collaborators at University of California, San Francisco (UCSF) are studying the genetic causes of disorders of cognition and epilepsy, in particular disorders of brain development that affect the corpus callosum, such as Aicardi syndrome, as well as two additional brain malformations, polymicrogyria and Dandy-Walker malformation. The goal of the investigators' research is to use a better understanding of the underlying genetic causes as a foundation to develop better treatments for these groups of patients.

Based on our current understanding of Aicardi syndrome, the condition is hypothesized to occur due to a genetic change on the X-chromosome. The research team is investigating Aicardi syndrome to identify the specific gene location associated with the disorder. The investigators are collecting blood and skin biopsy samples from patients and their parents. A permanent cell line is prepared and DNA from the blood and skin samples and cell lines is isolated and then used for genetic testing. The current research includes microarray analysis which which is used to look for duplications or deletions of genetic material, mutation analysis of candidate genes by sequencing, genome-wide sequencing, review of medical records to identify trends suggesting possible candidate genes of interest, and X chromosome inactivation studies.
