Familial cerebral cavernous malformation: report of a further Italian family.
Cerebral cavernous malformations (CCMs) are vascular abnormalities that may cause seizures, headaches, intracerebral hemorrhages, and focal neurological deficits; they can also be clinically silent and may occur as a sporadic or an autosomal dominant condition. Three genes have been identified as causing familial CCM: KRIT1/CCM1, MGC4607/CCM2, and PDCD10/CCM3, mapping, respectively, on chromosomes 7q, 7p, and 3q. This is a report on an Italian family affected by CCM due to a KRIT1 gene mutation on exon 13. The mother suffered from a cerebellar hematoma and was severely disabled; one son had suffered from intractable seizures and underwent surgery for removal of a cavernous angioma, while another son was asymptomatic. Brain MRI showed CCMs in all patients. This report underlines that a familial form of CCM could be suspected when a patient presents with multiple CCMs; neurologists and neurosurgeons should be aware that genetic testing for these forms is available.
