This is a genotype with recommended actions if clinically confirmed. In brief:
- Familial cerebral cavernous malformation (FCCM) is a vascular malformation disorder characterized by closely clustered irregular dilated capillaries (caverns) that can cause variable neurological manifestations such as seizures, nonspecific headaches, progressive or transient focal neurologic deficits, and/or cerebral hemorrhages.
- Mutations in the CCM2, KRIT1, and PDCD10 genes may lead to FCCM.
- Regular check-ups, generally with an MRI once a year, are recommended after the discovery of a CCM, as additional asymptomatic lesions may appear with time.
- Surgical removal of CCMs has traditionally been indicated for lesions associated with intractable seizures or focal deficits from recurrent hemorrhage or mass effect.
- Pregnant women with FCCM who have had recent brain or spinal cord hemorrhage, epilepsy, or migraine require closer monitoring during pregnancy.
- Individuals with FCCM mutations should avoid antithrombotic and certain analgesic medications, and also avoid radiation.
