HIP1 and epilepsy: Most deletions included HIP1 and YWHAG, with the exception of patient #4 and patient #9 described by Ramocki et al. Most patients had considerably larger deletions extending to the centromeric and/or telomeric sides, which could include the region responsible for the Williams-Beuren syndrome and 2 other candidate genes for a phenotype of epilepsy and neurodevelopmental abnormalities, KIAA0442 and MAGI2.
