Cerebral cavernous malformations (CCM), also known as cavernous angioma, cavernous haemangioma, and cavernoma, is a vascular disorder of the central nervous system that may appear either sporadically or exhibit autosomal dominant inheritance. The incidence in the general population is between 0.1-0.5% and clinical symptoms typically appear between 30 to 50 years of age. Once thought to be strictly congenital, these vascular lesions have been found to occur de novo. The vertebrate central nervous system consists of the brain and spinal cord. ... An autosomal dominant gene is an abnormal gene on one of the autosomal (non-sex determining) chromosomes. ...

This disease is characterized by grossly dilated blood vessels with a single layer of endothelium and an absence of neuronal tissue within the lesions. Blood vessels in patients with CCM can range from a few millimeters to several centimeters in diameter. The endothelium is the layer of thin, flat cells that lines the interior surface of blood vessels, forming an interface between circulating blood in the lumen and the rest of the vessel wall. ...

Many patients live their whole life without knowing they have a cerebral cavernous malformation. Other patients can have severe symptoms like seizures, headaches, paralysis, bleeding in the brain (cerebral hemorrhage), and even death. The nature and severity severity of the symptoms depend on the lesion's location in the brain. Approximately 70% of these lesions occur in teh supratentorial region of the brain; the remaining 30% occur in the infratentorial region. A cerebral hemorrhage is bleeding directly into the brain parenchyma (tissue) itself, otherwise known as hemorrhagic stroke. ...

Clinical symptoms of this disease include recurrent headaches, focal neurological deficits, hemorrahagic stroke, and seizures, but CCM can also be asymptomatic. The lesions can be detected by magnetic resonance imaging (MRI) which can also be used to detect clinically silent lesions. A headache is a condition of mild to severe pain in the head; sometimes upper back or neck pain may also be interpreted as a headache. ... A stroke or cerebrovascular accident (CVA) occurs when the blood supply to a part of the brain is suddenly interrupted by occlusion (an ischemic stroke- approximately 90%of strokes) or by hemorrhage (a hemorrhagic stroke - approximately 10% of strokes). ... This article is about the medical condition. ... In medicine, a disease is asymptomatic when it is at a stage where the patient does not experience symptoms. ... Magnetic resonance imaging (MRI) - also called magnetic resonance tomography (MRT) - is a method of creating images of the inside of opaque organs in living organisms as well as detecting the amount of bound water in geological structures. ...

Familial forms of CCM occur at three known genetic loci. The gene for CCM1 encodes KRIT1 and has been found to bind to ICAP1alpha, an integrin cytoplasmic-domain associated protein. The gene for CCM2 encodes a novel protein named "malcavernin" that contains a phosphotyrosine (PTB) binding domain. The exact biological function of CCM2 is currently unknown. The CCM3 gene was recently identified as PDCD10 (programmed cell death 10), which was initially identified as a gene that is up-regulated during the induction of apoptosis (cell death) in TF-1, a human myeloid cell line. The precise role of the PDCD10 protein in the CCM pathway that has been established to this point has not yet been determined. Research is ongoing to determine the function and properties of all three CCM gene products as well as the reaction pathways in which they are involved. An integrin, or integrin receptor, is an integral membrane protein in the plasma membrane of cells. ... In biology, apoptosis (from the Greek words apo = from and ptosis = falling, pronounced ap-a-tow-sis[1]) is one of the main types of programmed cell death (PCD). ... Myeloid cells is a subsummating term for all hemopoietic cells except the lymphoid ones (T-cells, B-cells, NK-cells, dendritic cells). ...

Mutations in these three genes account for 70 to 80 percent of all cases of cerebral cavernous malformations. The remaining 20 to 30 percent of cases may be due to other, still unidentified, genes.
