MeSH (18) and Staals et al. 55 Kenosia Avenue Probands' father had severe hypermetropia and bilateral cataracts. Unauthorized use of these marks is strictly prohibited. Zeeva woke up after a ten-hour procedure, opened her eyes, and it felt like we were seeing her for the first time. PMC However, there are exceptions that depend on precisely when and where the mutation arose. What does it mean if a disorder seems to run in my family? mutations: a novel genetic multisystem disease. Accessibility Our experience with Boston Childrens was very different from the other places we had been for epilepsy and neurology treatment. Patients must rely on the personal and individualized medical advice of their qualified health care professionals before seeking any information related to their particular diagnosis, cure or treatment of a condition or disorder. Ophthalmological features associated with COL4A1 mutations. MedlinePlus links to health information from the National Institutes of Health and other federal government agencies. Mutations in COL4A1 or COL4A2 cause Gould Syndrome and, because these two proteins are found in almost all tissues; nearly any organ can be affected. doi: 10.1038/jp.2013.135, 29. N Engl J Med. (2013) 73:4857. 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. 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. The networks formed by the COL4A1 and COL4A2 proteins are called basement membranes and are present in every organ of the body. Brain magnetic resonance imaging (MRI) scans were carried out on a three Tesla Brain MRI (Achieva, Ingenia; Philips Healthcare, Best, The Netherlands). Ann Other phenotypes include intracranial aneurysms, porencephaly, infantile hemiparesis, muscle cramps, optic nerve dysgenesis and secondary glaucoma. COL4A1/A2-related disorders are caused by dominant mutations in the COL4A1 or COL4A2 genes. 2022 Oct 26;7(44):39680-39689. doi: 10.1021/acsomega.2c03360. (D) III- 3Brain MRI showed small asymptomatic lesions in white matter. 1779 Massachusetts Avenue Other eye problems associated with HANAC syndrome include a clouding of the lens of the eye (cataract) and an abnormality called Axenfeld-Rieger anomaly. Powered by NORD, the IAMRARE Registry Platform is driving transformative change in the study of rare disease. The COL4A1 and COL4A2 genes were screened in proband IV-6. Here, we report a patient with schizencephaly, detected by fetal ultrasonography and fetal magnetic resonance imaging, with a de novo novel mutation in COL4A1 (c.2645_2646delinsAA, p.Gly882Glu). 1A-B). If neither parent carries the mutation, it is considered de novo which means that the mutation is a new occurrence. II-2 had a limp since childhood attributed to forceps delivery. Additional features include poor or absent speech development, facial paralysis (paresis), involuntary muscle spasms (spasticity) that result in slow, stiff, rigid movements, visual field defects, and hydrocephalus, a condition in which accumulation of excessive cerebrospinal fluid in the skull causes pressure on the tissues of the brain, resulting in a variety of symptoms. At least 50 individuals with this condition have been described in the scientific literature. The non-working gene can be inherited from either parent or can be the result of a mutated (changed) gene in the affected individual (called sporadic or de novo). The reference sequences were NM_001845.4 (NP_001836.2) for COL4A1 and NM_001846.2 (NP_001837.2) for COL4A2. 2021 Sep 10;13:727590. doi: 10.3389/fnagi.2021.727590. The COL4A1 gene has 52 exons and most of the pathogenic variants are distributed across exons 10 to 47 in the triple-helix domain. (2017) 377:111931. Clipboard, Search History, and several other advanced features are temporarily unavailable. Combinations of the in silico tool MutationTaster (21) and the Alamut software (ALAMUT package, http://www.interactivebiosoftware.com, France) predicted the variant to be pathogenic as it likely alters the protein structure/function due to a detrimental effect on 112 heterotrimers formation and type IV collagen stability. It is ubiquitously expressed in many tissues and cell types. doi: 10.1038/nmeth.2890, 22. This is called genotype-phenotype correlation. Depending on the cell type that acquires the mutation and when the mutation arises, the individual may have many or few cells with the mutation. 2017;155:45-57. https://www.ncbi.nlm.nih.gov/pubmed/28254515, Alavi MV, Mao M, Pawlikowski BT, et al. Quincy, MA 02169 COL4A1-related brain small-vessel disease is a rare condition, although the exact prevalence is unknown. (2012) 54:56974. Cereb Circ Cogn Behav. 2017 Jan;66:100-103. doi: 10.1016/j.pediatrneurol.2016.04.010. View CNBC interview with NORDs Peter Saltonstall and Boston Childrens Dr. Olaf Bodamer emphasizing the importance of investment in rare diseases. Type IV Collagens and Basement Membrane Diseases: Cell Biology and Pathogenic Mechanisms. COL4A1 -related brain small-vessel disease is characterized by weakening of the blood vessels in the brain. TTY: (866) 411-1010 Aicardi-Goutieres syndrome - About the Disease - Genetic and Rare Diseases Information Center National Center for Advancing Translational Sciences Browse by Disease About GARD Contact Us We recently launched the new GARD website and are still developing specific pages. my mom suggested we call Boston Childrens Hospital. For example, networks of COL4A1 and COL4A2 are present in the basement membranes of blood vessels. Prenatal clinical manifestations in individuals with COL4A1/2 variants. However, in rare pathologies with few cases, we may have missed undescribed or subclinical manifestations. This is an open-access article distributed under the terms of the Creative Commons Attribution License (CC BY). The conditions in this group have a range of signs and symptoms that involve fragile blood vessels. What is the prognosis of a genetic condition? Patients must rely on the personal and individualized medical advice of their qualified health care professionals before seeking any information related to their particular diagnosis, cure or treatment of a condition or disorder. sharing sensitive information, make sure youre on a federal Cerebral small vessel disease with hemorrhage is likely milder continuum from porencephaly and exhibits many of the same symptoms (with the exception of the brain cavities). https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3459649/, Federico A, Di Donato I, Bianchi S, et al. As the name suggests, mutations in the COL4A1 gene cause COL4A1-related brain small vessel disease. This report highlights both the broad spectrum of COL4A1 mutations and the yield of testing the COL4A1 gene in familial ophthalmological and brain disorders. Thats not to say Zeeva hasnt had to work hard since the surgery. 2018;61:765-772. Because the collagen is found throughout the body, COL4A1/A2 affects many organ systems, including the brain, kidneys, eyes, and muscles. doi: 10.1212/01.WNL.0000123113.46672.68, 25. We connect and coordinate our families with researchers and medical professionals to get our disease and management coordination into the medical realm. Suite 310 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). Cerebrovascular disease related to COL4A1 mutations in HANAC syndrome. (2007) 357:268795. We provide education, advocacy, and resources for families and individuals affected. COL4A1 is an essential component for basal membrane stability. PV and VW followed the children at the Neuropediatrics clinic of the same hospital. Mutations in COL4A3, COL4A4 and COL4A5 were found in the early 1990's in patients with Alport Syndrome. functional hemispherectomy. 8600 Rockville Pike The expanding phenotype of COL4A1 and COL4A2 mutations: clinical data on 13 newly identified families and a review of the literature. 2015;84:918-926. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4351667/, Meuwissen ME, Halley DJ, Smit LS, et al. doi: 10.1136/jmg.2005.035584, 15. COL4A1/A2-related disorders are rare, genetic, multi-system disorders. The expanding phenotype of COL4A1 and COL4A2 mutations: clinical data on 13 newly identified families and review of the literature. 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. To better define pathology caused by Col4a1 mutations, we characterized myopathy in two different Col4a1 mutant mouse strainsCol4a1 ex41 and Col4a1 G394V.We selected these strains from an allelic series of Col4a1 mutant mice because they showed the most severe myopathy according to NPN quantification in quadriceps while having different effects on [1(IV)] 2 2(IV) secretion. He would separate the two halves of her brain by The severity of the condition varies greatly among affected individuals. Porencephaly refers to the formation of fluid-filled cysts or cavities within of the brain. Neurology. 4 Both . eCollection 2022. So far, it appears as though mutations in COL4A1 and COL4A2 lead to identical disease, however, for reasons that are not yet understood, mutations in COL4A2 are much less frequent than those in COL4A1. Cataracts, which are a clouding of the lenses of the eyes, are often present from birth (congenital) and may be one of the first identifiable signs of the syndrome. doi: 10.1126/science.1109418, 5. After a normal neonatal period, those affected develop a rapidly progressive course involving irritability, hyperaesthesia, visual and hearing loss, severe cognitive and motor deterioration, and seizures. Stroke. COL4A1-related brain small-vessel disease is part of a group of conditions called the COL4A1-related disorders. The pathogenic mechanisms of COL4A1 mutations are not fully elucidated and may vary according to the mutation type, the affected exon (mutations responsible for systemic HANAC syndrome cluster at exon 24 and 25), the position of the mutation within the triple-helix domain, and the mutation location. COL4A1 mutations as a monogenic cause of cerebral Information on current clinical trials is posted on the Internet at https://clinicaltrials.gov/. Phone: 617-249-7300, Danbury, CT office In affected individuals, stroke is usually caused by bleeding in the brain (hemorrhagic stroke) rather than a lack of blood flow in the brain (ischemic stroke), although either type can occur. We are a registered 501(c)3 Nonprofit dedicated to providing hope and help to children and adults with Gould Syndrome; affecting COL4A1 and COL4A2 genes. Early intervention is important in ensuring that children with reach their highest potential. doi: 10.1055/s-0031-1275343, 24. Standardized human pedigree nomenclature: update and assessment of the recommendations of the National Society of Genetic Counselors. Nat Methods. In addition to porencephaly there can be other forms of damage to the brain present at birth. When we didnt feel we had any options left for treatment, 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. Some people with COL4A1-related brain small-vessel disease have an eye abnormality called Axenfeld-Rieger anomaly. Genetic counseling will be proposed when IV-3 and IV-6 intend to start a family as there is a 50% risk of mutation transmission to the next generation and potential obstetrical complications. Basement membranes without these networks are unstable, leading to weakening of the tissues that they surround. (2011) 42:13. 1900 Crown Colony Drive What does it mean if a disorder seems to run in my family? The timeline for the clinical examination and ancillary tests performed is illustrated in Figure 2. Figure 3. A similar term, variable expressivity, describes when affected individuals have widely varying signs and symptoms. No ophthalmological surgery was planned on annual control for any member, but only positive lens correction prescribed. official website and that any information you provide is encrypted When a mutation occurs in one of these genes, the rope does not wind up properly and it stays inside the cell. The main symptom is single or repeated bleeding inside the skull (intracranial hemorrhaging) that can occur without cause (spontaneously), after trauma, or when taking drugs that slow blood clotting (anticoagulants). (For more information on this disorder, choose cadasil as your search term in the Rare Disease Database. 2009 Jun 25 [Updated 2016 Jul 7]. The limitations include the limited number of tested members (only two generations) due to a large family spread over Europe and not fully accessible. IV-3 and IV-6 are closely followed by a neuropediatrician (VW). Facebook: https://www.facebook.com/Col4A1Foundation Please Note This is not specific to COL4A1/A2-related disorders, and is a sign of many different types of muscle disease. A dashed arrow indicates secondary atrophy in the left cerebral peduncle. These types of correlations can be difficult to detect in patients because of the broad genetic variability in humans. Since fewer than 100 families have been reported, the exact prevalence of COL4A1-related disorders is not well-established. In most people, small vessel disease in the brain does not cause symptoms. (2014) 15:16. This study clearly demonstrates that COL4A1 and COL4A2 mutations cause clinically variable cerebrovascular disease that includes characteristic features of cerebral small vessel disease. Antiinflammatory therapy with canakinumab for atherosclerotic disease. N Engl J Med. See our, COL4A1-related brain small-vessel disease, URL of this page: https://medlineplus.gov/genetics/condition/col4a1-related-brain-small-vessel-disease/. Fetal origin of brain damage in 2 infants with a COL4A1 mutation: fetal and neonatal MRI. Deml B, Reis LM, Maheshwari M, Griffis C, Bick D, Semina E. Whole exome analysis identifies dominant COL4A1 mutations in patients with complex ocular phenotypes involving microphthalmia. Services that may be beneficial for some affected individuals include medical, social, and/or vocational services such as special remedial education. For example, Type I collagen mutations cause Osteogenesis Imperfecta (brittle bone disease), Type II collagen mutations cause chondrodysplasias (defects of cartilage) and mutations in Type III collagen cause a form of Ehlers-Danlos Syndrome. COL4A1 brain small-vessel disease is an autosomal dominant condition resulting from a mutation to the COL4A1 gene, located on the long arm of chromosome 13, that normally encodes for the alpha-1 chain of type IV collagen 1-6. The effects of the disorder range from subtle or mild to severe, depending on associated brain abnormalities. She had seizures every day, couldnt gain weight, sleep right, or generally enjoy her life. Until just this year, her 16-year-old daughter Emily, who #1 Ranked Childrens Hospital by U. S. News & World Report. Contact a health care provider if you have questions about your health. Neurovascular Alterations in Vascular Dementia: Emphasis on Risk Factors. Plaisier E, Gribouval O, Alamowitch S, Mougenot B, Prost C, Verpont MC, et al. ClinVar; [VCV000389182.3]. Standardized (15) familiar pedigree is showed in Figure 1. When our 8-year-old daughter, Zeeva, giggles and runs in her walker to the swing set, its like watching pure childhood joy. doi: https://www.ncbi.nlm.nih.gov/pubmed/20558831, Alamowitch S, Plaisier E, Favrole P, et al. Exome sequencing in 32 patients with anophthalmia/microphthalmia and developmental eye defects. I dont think we will ever be able to truly articulate our appreciation for Dr. Madsen and Boston Childrens for all that they did for Zeeva and our family. Compared to other COL4A1-related disorders, the brain is only mildly affected in HANAC syndrome. Graefe's Arch Clin Exp Ophthalmol. (2010) 75:7479. Bennett RL, French KS, Resta RG, Doyle DL.
