Note that data from the following are not included in the table: five individuals who have only 4p deletions do not have seizures. An additional five individuals in the cohort with only 4p deletions do have seizures but did not specify the type of seizures they had, and so could not be included in this table. One individual with multiple CNVs had seizures but also did not specify kind.
