Abstract

Cerebral cavernous malformations (CCM) are vascular lesions that predispose to headaches, seizures, and hemorrhagic stroke. Hereditary CCMs are usually associated with the occurrence of multiple CCMs and occur with a frequency of 1:2,000 to 1:10,000. In this study, eight isolated cases with multiple CCMs but no CCM1-3 point mutation were analyzed using the multiplex ligation-dependent probe amplification assay. Four genomic rearrangements were identified including a previously unreported large duplication within the CCM1 gene and a novel deletion involving the entire coding region of the CCM2 gene. Consequently, systematic screening for CCM deletions/duplications is recommended.
