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.
