Teaching families how to advocate for their loved ones and access medical information. The size and location of cerebral cavities contributes to clinical variability. Last updated: The brain MRI of IV-6 disclosed a large right-sided frontoparietal cavity (Figure 3B) with communication to the lateral ventricle, isosignal to CFS. Stroke is a leading cause of death and serious long-term disability in developed nations. (2015) 17:40524. The COL4A1 gene mutations that cause COL4A1-related brain small-vessel disease result in the production of a protein that disrupts the structure of type IV collagen. Arterial retinal tortuosity can cause episodes of bleeding within the eye following any minor trauma to the eye, leading to temporary vision loss.

Some individuals do not have any observable symptoms (asymptomatic); others can develop severe, even life-threatening complications. Axenfeld-Rieger anomaly is associated with various other eye abnormalities, including underdevelopment and eventual tearing of the colored part of the eye (iris), and a pupil that is not in the center of the eye. Mosaic individuals are likely less severely affected, or even asymptomatic, because they have many cells that secrete COL4A1 normally and that can compensate for those cells that cannot. Curr Opin Neurol. How can gene variants affect health and development? Volonghi I, Pezzini A, Del Zotto E, Giossi A, Costa P, Ferrari D, Padovani A. Suite 310 Neurol. In the back of the eye, affected individuals have also twisting or distortion (tortuosity) of arteries in the retina (bilateral retinal arterial tortuosity) as part of the syndrome or as an isolated finding. This study clearly demonstrates that COL4A1 and COL4A2 mutations cause clinically variable cerebrovascular disease that includes characteristic features of cerebral small vessel disease. Progressive cerebral atrophies in three children with COL4A1 mutations.

Rouaud T, Labauge P, Lasserve ET, Mine M, Coustans M, Deburghgraeve V, et al. Rarely, affected individuals will have a condition called Raynaud phenomenon in which the blood vessels in the fingers and toes temporarily narrow, restricting blood flow to the fingertips and the ends of the toes. Due to the rarity of the disease, there are no treatment trials that have been tested on a large group of patients. For example, if the mutation arises during the formation of the sperm or the egg, then all of the cells that make up the child will carry the mutation. cutting tissue called the corpus callosum, then make some additional delicate Probands' father had severe hypermetropia and bilateral cataracts. CADASIL patients can experience progressive memory loss, deterioration of intellectual abilities and loss of balance with a progressive worsening of these symptoms, but symptoms are usually less severe and occur later in life. We describe, here, the phenotype of a likely pathologic variant (p.Gly743Val) in exon 30 of the COL4A1 gene, responsible for an oculo-cerebral phenotype characterized by severe hypermetropia and highly penetrant porencephaly in absence of other systemic complications. Phone: 617-249-7300, Danbury, CT office The COL4A1 gene has 52 exons and most of the pathogenic variants are distributed across exons 10 to 47 in the triple-helix domain. Mosaicism can contribute to both reduced penetrance or variable expressivity but other factors do as well. Eur J Paediatr Neurol. This condition is inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to cause the disorder. IV-3 was diagnosed with ventriculomegaly in utero. TTY: (866) 411-1010 doi: 10.1007/s10897-008-9169-9, 16. For asymptomatic patients, cerebral and vessel imaging for aneurysm screening and ophthalmologic follow-up are indicated (2). Mice with Col4a1 and Col4a2 gene mutations have pathology in many organs and the presence and severity of pathology in a given organ appears to depend on the location of the mutation, genetic context, and environmental interactions.

The conditions in this group have a range of signs and symptoms that involve fragile blood vessels. Figure 3. BMC Med Genet. At 2 years old, IV-6 presented obvious left hemiparesis but could move without help. Brain magnetic resonance imaging (MRI) scans were carried out on a three Tesla Brain MRI (Achieva, Ingenia; Philips Healthcare, Best, The Netherlands). (D) III- 3Brain MRI showed small asymptomatic lesions in white matter. This condition is inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to cause the disorder. Changing lives of those with rare disease. Bookshelf The proportion of cases caused by a de novopathogenic variant is estimated to be at least 27%. COL4A1 is an essential component for basal membrane stability and exon mutations of COL4A1 gene mutations are responsible for a broad spectrum of systemic manifestations characterized by small vessel involvement of variable severity, including neurological (1) [porencephaly (24), hemorrhage (2, 57) and aneurysms (8)], ophthalmological (912) (retinal artery tortuosity, Axenfeld Rieger anomalies, cataracts, and severe hypermetropia), renal (13) (renal cysts, and microscopic hematuria), and systemic (13) findings (cramps with a high creatine kinase level [CK], Raynaud's phenomenon, and arrhythmias).

This condition causes mutations in genes that produce a specific type of collagen. U.S. Department of Health and Human Services, Autosomal dominant familial hematuria, retinal arteriolar tortuosity, contractures, Hereditary angiopathy with nephropathy, aneurysm, and muscle cramps syndrome. Developmental defects to the front of the eye, which also includes the ocular drainage structures between the iris and cornea, can lead to increased pressure in the eye (elevated intraocular pressure, or IOP). Bethesda, MD 20894, Web Policies Muscle cramps experienced by most people with HANAC syndrome typically begin in early childhood. (2008) 17:42433. The team may eventually include pediatric neurologists (diagnose and treat disorders of the brain, nerves and nervous system in children); ophthalmologists (who specialize in eye disorders) hematologists (who specialize in blood disorders); cardiologists (who specialize in heart disorders, nephrologists (who specialize in kidney disorders) and other healthcare professionals may need to systematically and comprehensively plan treatment. IV-3 had a left hemisphere porencephalic cyst and the lack of evidence of a left corticospinal tract on tractography (Figures 3E,F), IV-5 had a porencephalic cyst on the right lateral ventricle (Figure 3C), and III-3 had leukoencephalopathy (Figure 3D). Smoking, which also increases the risk of stroke, physical activities that can cause head trauma such as contact sports, and the use of anti-clotting (anticoagulant) medications, should be avoided. Affected individuals have kidney disease (nephropathy) causing blood in the urine (hematuria) that can either be seen by the naked eye (gross hematuria) or only visible when tested (microscopic hematuria). This blood vessel abnormality can cause episodes of bleeding within the eyes following any minor trauma to the eyes, leading to temporary vision loss.

Resource(s) for Medical Professionals and Scientists on This Disease: Aguglia U, Gambardella A, Breedveld GJ, Oliveri RL, Le Piane E, Messina D, et al. As the name suggests, mutations in the COL4A1 gene cause COL4A1-related brain small vessel disease. For example, treatment may include physical therapy, speech therapy, anti-convulsant medications for seizures, and a shunt to treat hydrocephalus by draining excess fluid from the skull. National Taiwan University Hospital, Taiwan, Kaohsiung Chang Gung Memorial Hospital, Taiwan, Carrera de Medicina, Universidad Cientfica del Sur, Peru, Federal University of Rio Grande do Sul, Brazil. doi: 10.1001/archophthalmol.2010.42, 10. In a retrospective study of 52 patients with COL4A1 mutations, stroke occurred in 17.3% of subjects and MRI showed white matter abnormalities (63.5%), subcortical microbleeds (52.9%), porencephaly (46%), enlarged spaces around blood vessels, (19.2%), and small infarctions (13.5%). doi: The ultimate goal of IAMRARE is to unite patients and research communities in the improvement of care and drug development.

Our data testing the effects of established mutations on collagen biosynthesis suggest that the intracellular retention of mutant COL4A1 proteins at the expense of their secretion appears to be a common effect of many COL4A1 mutations. Type IV collagen networks play an important role in the basement membranes in virtually all tissues throughout the body, particularly the basement membranes surrounding the body's blood vessels (vasculature). What is the prognosis of a genetic condition? Given the variable expressivity of these mutations, COL4A1/A2-related disorders are likely under diagnosed and the exact number of people who have these disorders is unknown.
