Another limitation is the systemic work-up based on described phenotypes and supposed affected organs. 2009 Dec 1;73(22):1873-82. doi: 10.1212/WNL.0b013e3181c3fd12. Novel COL4A1 mutations associated with HANAC syndrome: a role for the triple helical CB3[IV] domain. (2014) 83:122834. How are genetic conditions treated or managed? 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. Keywords: COL4A1, Type IV collagen, familial porencephaly, ocular malformations, variable expressivity, Citation: Scoppettuolo P, Ligot N, Wermenbol V, Van Bogaert P and Naeije G (2020) p.Gly743Val Mutation in COL4A1 Is Responsible for Familial Porencephaly and Severe Hypermetropia. National Center for Biotechnology Information. 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). Some of these patients have been described as having HANAC syndrome, which is an acronym for hereditary angiopathy, nephropathy, aneurysms, and muscle cramps. (D) III- 3Brain MRI showed small asymptomatic lesions in white matter. The COL4A1 gene provides instructions for making one component of a protein called type IV collagen. 1A-B). Slavotinek AM, Garcia ST, Chandratillake G, Bardakjian T, Ullah E, Wu D, et al. doi: 10.1136/jmg.2005.035584, 15. (2005) 308:116771. doi: 10.1055/s-0031-1275343, 24.

Copyright 2023 by Gould Syndrome Foundation -. 2009 Jun 25 [updated 2016 Jul 7]. IV-5 had microcephaly without motor deficits, a language delay, a mental retardation (IQ of 62) that required adapted schooling, and severe hypermetropia. Hereditary angiopathy with nephropathy, aneurysms, and muscle cramps (HANAC) syndrome is part of a group of conditions called the COL4A1 -related disorders. However, it is also very likely that basement membrane defects also contribute to abnormal signaling and function of cells that form blood vessels in the brain and elsewhere. They are typically characterized by abnormal blood vessels in the brain (cerebral vasculature defects), eye development defects (ocular dysgenesis), muscle disease (myopathy), and kidney abnormalities (renal pathology); however, many other aspects of the syndrome including abnormalities affecting the structure of the brain (cerebral cortical abnormalities) and lung (pulmonary) abnormalities continue to emerge and the full spectrum is still uncharacterized. (1982) 40:5679. 2012;322:25-30. https://www.ncbi.nlm.nih.gov/pubmed/22868088, Shah S, Ellard S, Kneen R, et al. The expanding phenotype of COL4A1 and COL4A2 mutations: clinical data on 13 newly identified families and a review of the literature. Other causes of porencephaly were ruled out [maternal alloimmunization, trauma, peri-natal cerebral ischemia (normal Apgar scores at birth), and negative TORCH complex tests]. The conditions in this group have a range of signs and symptoms that involve fragile blood vessels. Shah S, Kumar Y, McLean B, Churchill A, Stoodley N, Rankin J, et al. COL4A1 mutations are responsible for a wide range of abnormalities affecting mainly the brain and the retinal vasculature, the anterior and posterior ocular structures and the renal glomerules. This review dsecribes the clinical spectrum of a newly identified disorder related to COL4A1 gene mutations. Ultrasound in utero from IV-6 (A). Therefore, it is important to note that there is a very broad spectrum of clinical presentations with different organs affected to different degrees between patients. The human phenotypes are extremely variable between patients and between families, with disease onset as early as in the fetal period. doi: 10.1002/ana.23736, 4. Surgery or endovascular therapy can be used to treat intracranial hemorrhage. Type IV collagen molecules attach to each other to form complex protein networks. Information on current clinical trials is posted on the Internet at https://clinicaltrials.gov/. Matrix Biol. COL4A1 and COL4A2 are on Chr. doi: 10.1007/s10897-008-9169-9, 16.

MeSH Many patients with COL4A1 and COL4A2 mutations have additional signs and symptoms that do not include the cerebral vasculature. U.S. Department of Health and Human Services, Brain small-vessel disease with hemorrhage. Epub 2022 Apr 14. Acute urinary retention due to a novel collagen COL4A1 mutation. Some affected individuals may develop weakness or paralysis of one side of the body (hemiparesis or hemiplegia) and have seizures. But she is learning to read, enjoys swimming, horseback riding, and is a glass jewelry and pottery artist. Aneurysms are bulges or enlargements of a blood vessel caused by weakening of the wall of the blood vessel. Science. We therefore began our analysis of mutant Col4a1 G498V mice by examining the retinal vascular network at three and nine months of age. 55 Kenosia Avenue (For more information on this disorder, choose cadasil as your search term in the Rare Disease Database. NCI CPTC Antibody Characterization Program. MedlinePlus also links to health information from non-government Web sites. In her first six years of life, Zeeva spent hundreds of nights in the hospital, had 13 operations and countless procedures, (from eye surgeries to Achilles heel, a shunt placed in her brain, and spine surgery). Muscle cramps experienced by most people with HANAC syndrome typically begin in early childhood. After the COL4A1 mutation was found, systemic manifestations of COL4A1 mutations were investigated. mutation in Axenfeld-Rieger anomaly with leukoencephalopathy and stroke. The variant was found in IV-3 and IV-5 and not in asymptomatic relatives (III-4, IV-1, IV-4). Additionally, consultation with a genetic counselor is strongly recommended for affected individuals and their families and psychosocial support for the entire family is essential. The variant was confirmed by bidirectional fluorescence DNA sequencing (Sanger method). In people with HANAC syndrome, angiopathy affects several parts of the body. (2008) 17:42433. All authors contributed to the article and approved the submitted version. Rarely, new mutations in the gene occur in people with no history of the disorder in their family. In people with COL4A1-related brain small-vessel disease, the vasculature in the brain weakens, which can lead to blood vessel breakage and stroke. At the age of 12, IV-3 underwent cerebral palsy quality of life (CPQoL) questionnaires in which they expressed a satisfactory quality of life and a good relationship with other children. She also showed severe hypermetropia. Until just this year, her 16-year-old daughter Emily, who #1 Ranked Childrens Hospital by U. S. News & World Report. Epub 2014 Jan 5. Other phenotypes include intracranial aneurysms, porencephaly, infantile hemiparesis, muscle cramps, optic nerve dysgenesis and secondary glaucoma. (No doctor had ever taken a call on their lunch break to speak with me). Individuals with this condition are at increased risk of having more than one stroke in their lifetime. Fazekas F, Chawluk JB, Alavi A. MR signal abnormalities at 1.5 T in Alzheimer's dementia and normal aging. A Podcast For The Rare Disease Community, Policy Statements & Letters to Policymakers. GeneReviews. Staals J, Makin SDJ, Doubal FN, Dennis MS, Wardlaw JM. This variant p.Gly743Val combines hypermetropia in all heterozygotic patients and highly penetrant antenatal porencephaly (associated with motor and intellectual deficits). How can gene variants affect health and development? Abnormal retinal arteries are prone to rupture causing bleeding associated with temporary loss of vision or even retinal detachments that can cause permanent vision loss. Fragile or damaged blood vessels or basement membranes in the kidneys can lead to blood in the urine (hematuria). Our review highlights that COL4A1 mutations can present for the first time in adult life with features of cerebral SVD, including subcortical hemorrhage and ischemic stroke, . Basement membranes without these networks are unstable, leading to weakening of the tissues that they surround. In the human genome, there are 46 chromosomes. Gould Syndrome is often characterized by abnormal blood vessels in the brain (cerebral vasculature defects), eye development defects (ocular dysgenesis), muscle disease (myopathy), and kidney abnormalities (renal pathology); however, many other aspects of the syndrome including abnormalities affecting the structure of the brain (cerebral cortical abnormalities) and lung (pulmonary) abnormalities continue to emerge and the full spectrum is still uncharacterized. The risk is the same for males and females. The proportion of cases caused by a de novopathogenic variant is estimated to be at least 27%. Feb;24(1):63-8. doi: 10.1097/WCO.0b013e32834232c6. However, in people with HANAC syndrome, these aneurysms typically do not burst. Doctors and researchers to bring research and medical therapeutic options to those affected. It is possible that insufficient collagen in the basement membrane predisposes blood vessels in the brain to leak or rupture. (2006) 43:4905. Jeanne M, Gould DB. Suggestive evidence for linkage to chromosome 13qter for autosomal dominant type 1 porencephaly. 1. COL4A1-related brain small-vessel disease is part of a group of conditions called the COL4A1-related disorders. Recent findings: Raynaud phenomenon is typically triggered by changes in temperature and usually causes no long term damage. For the nucleotide numbering, the HVGS terms (www.hgvs.org) were applied with the nucleotide A of the ATG startcodon = c.1. The type IV collagens are encoded by six different genes (COL4A1, COL4A2, COL4A3, COL4A4, COL4A5 and COL4A6). Xia XY, Li N, Cao X, Wu QY, Li TF, Zhang C, et al. Your support helps to ensure everyones free access to NORDs rare disease reports. It looks like nothing was found at this location. Focke JK, Veltkamp R, Bauer P, Kraemer M. J Neurol. Ensuring that patients and caregivers are armed with the tools they need to live their best lives while managing their rare condition is a vital part of NORDs mission.

J Neurol Sci. Progressive cerebral atrophies in three children with COL4A1 mutations. Cysts can also form in one or both kidneys, and the cysts may grow larger over time. (2013) 73:4857. NORD is a registered 501(c)(3) charity organization. Vahedi K, Alamowitch S. Clinical spectrum of type IV collagen (COL4A1) The management of COL4A1/A2-related disorders may require the coordinated efforts of a team of specialists. We connect and coordinate our families with researchers and medical professionals to get our disease and management coordination into the medical realm. These protein networks are the main component of basement membranes, which are thin sheet-like structures that separate and support cells in many tissues. We believe that the variant p.Gly743Val is likely pathogenic for several reasons. II-2 had a limp since childhood attributed to forceps delivery. Axenfeld-Rieger is a collection of abnormalities affecting the front of the eye including the iris (colored part of the eye) and cornea (abnormally small corneas called microcornea), which is the transparent membrane that covers the eyes. 2017;155:45-57. https://www.ncbi.nlm.nih.gov/pubmed/28254515, Alavi MV, Mao M, Pawlikowski BT, et al. COL4A1 mutations cause progressive retinal neovascular defects and retinopathy. This can lead to problems 1) if too much of the misfolded protein accumulates within cells, 2) if not enough of the protein exits the cells to form networks, and 3) occasionally, the presence of the mutant proteins outside the cells can interfere with the structure of the network. All individuals with this condition have arteries that twist and turn abnormally within the light-sensitive tissue at the back of the eyes (arterial retinal tortuosity). Brain magnetic resonance imaging (MRI) scans were carried out on a three Tesla Brain MRI (Achieva, Ingenia; Philips Healthcare, Best, The Netherlands). Symptoms that may occur in individuals with autosomal dominant type I porencephaly include migraines, weakness or paralysis of one side of the body (hemiparesis or hemiplegia), seizures, stroke, and dystonia, a group of neurological disorders characterized by involuntary muscle contractions that force the body into abnormal, sometimes painful, movements and positions. This page is currently unavailable. The X and Y chromosomes are called the sex chromosomes and the rest all are called 'autosomes'. (2009) 73:187382. 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. Vahedi K, Alamowitch S. Clinical spectrum of type IV collagen (COL4A1) doi: 10.2214/ajr.149.2.351, 19. Contact a health care provider if you have questions about your health. People with COL4A1-related brain small vessel disease also have leukoencephalopathy, which is a change in a type of brain tissue called white matter that can be seen with magnetic resonance imaging (MRI). The https:// ensures that you are connecting to the The COL4A1 and COL4A2 genes were screened in proband IV-6. Affected infants and children can exhibit delays in reaching developmental milestones and varying degrees of intellectual disability. came with risks and was the hardest decision we had ever faced, yet we felt 100 View CNBC interview with NORDs Peter Saltonstall and Boston Childrens Dr. Olaf Bodamer emphasizing the importance of investment in rare diseases. Am J Med Genet A. Plaisier E, Gribouval O, Alamowitch S, Mougenot B, Prost C, Verpont MC, et al. See our, COL4A1-related brain small-vessel disease, URL of this page: https://medlineplus.gov/genetics/condition/col4a1-related-brain-small-vessel-disease/. Only one copy of COL4A1 or COL4A2 needs to acquire a mutation in order to cause disease which means the mutations are Dominant thus, Gould Syndrome is considered Autosomal Dominant. Zagaglia Selch C, Nisevic JR, et al. Various treatments have been reported in the medical literature as part of single case reports or small series of patients. Similar blood vessel weakness and breakage occurs in the eyes of some affected individuals. 2008 May;192(5):971-84; discussion 984-6. Autosomal Dominant Brain Small Vessel Disease.

What does it mean if a disorder seems to run in my family? Together, these studies suggest that certain unknown variants of COL4A1 and COL4A2 might contribute to chronic vascular dysfunction. COL4A1/A2-related disorders follow an autosomal dominant pattern of inheritance. What are the different ways a genetic condition can be inherited? (For more information on these disorders, choose the specific disorder name as your search term in the Rare Disease Database.). 2022 Sep;269(9):5153-5156. doi: 10.1007/s00415-022-11111-0. doi: 10.1038/nmeth.2890, 22. https://www.ncbi.nlm.nih.gov/pubmed/20558831, Alamowitch S, Plaisier E, Favrole P, et al. For instance, retinal arteriolar tortuosity relates to mutations in the amino-terminal one-third of the protein while mutations causing cataracts and ocular morphologic alterations are more likely to occur, closer to the carboxy terminus (22), like the variant we report. In most people, small vessel disease in the brain does not cause symptoms. (2011) 42:13. We each inherit a full complement on autosomes from each of our parents giving us two copies of each gene. Aura refers to additional neurological symptoms that occur with, or sometimes before, the development of the migraine headache. Purpose of review: Treatment trials will be critical to determine the long-term safety and effectiveness of specific medications and treatments for individuals with COL4A1/A2-related disorders. (1987) 8:4216. Summary. 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. doi: 10.1038/gim.2014.210, 3. Am J Neuroradiol. Supporting children in their development to reduce handicaps and combining their follow-up with parent counseling could be considered as an ideal approach. The extents to which intracellular and/or extracellular insults contribute to pathology remain an open question. Phone: 203-263-9938 Common variation in COL4A1/COL4A2 is associated with sporadic cerebral small vessel disease. NORD and MedicAlert Foundation have teamed up on a new program to provide protection to rare disease patients in emergency situations. III-3 was informed of the genetic diagnosis and is now regularly followed and screened for cataracts and brain aneurysms. A dashed arrow indicates secondary atrophy in the left cerebral peduncle. Muscle cramps can be spontaneous or triggered by exercise. 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. COL4A1 is an essential component for basal membrane stability. Liu X, Yang Q, Tang L, He J, Tian D, Wang B, Xie L, Li C, Fan D. Front Neurol. Seattle, WA: University of Washington, Seattle; 1993-. COL4A1/A2-related disorders are caused by dominant mutations in the COL4A1 or COL4A2 genes. He also wanted to remove a shunt that was implanted in COL4A1 disorder is probably largely underestimated because of its multisystem and variable phenotype. Services that may be beneficial for some affected individuals include medical, social, and/or vocational services such as special remedial education. Individuals with COL4A1 or COL4A2 mutations can also develop formation of clefts or slits in the two halves of the brain (schizencephaly) in which cerebral hemispheres are missing and replaced with sacs filled with cerebrospinal fluid (hydranencephaly), abnormal folds in the brain surface (polymicrogyria) or abnormalities in the normal laying of the neuronal cells in the brain (cortical lamination defects). The p.Gly743Val variant is a conservative substitution that occurs in a position highly conserved across species (SIFT analysis: DeleteriousScore 0, median: 4.22, highly conserved nucleotide and amino acid, up to Tetraodon considering 11 species) and affects a crucial and abundant residue within the triple-helix-forming collagenous domain of the protein, which consist of long stretches of Gly-X-Y repeats. Advanced imaging techniques can include computerized tomography (CT) scanning and magnetic resonance imaging (MRI). These types of correlations can be difficult to detect in patients because of the broad genetic variability in humans. Research in mice with Col4a1 mutations suggests that the position of the mutation is very important. Curr Opin Neurol. The information on this site should not be used as a substitute for professional medical care or advice. People with HANAC syndrome develop kidney disease (nephropathy). Going from having seizures every day for six years to having no seizures is nothing short of a miracle. Neurology. Comparison of Clinical, Radiographic, and Histological Features in COL4A1 Syndrome Compared With Other Single Gene Disorders Causing SVD. As a result, type IV collagen molecules cannot attach to each other to form the protein networks in basement membranes. PV and VW followed the children at the Neuropediatrics clinic of the same hospital. Individuals with HANAC syndrome also experience a variety of eye problems. It is passed through families in a autosomal dominant fashion. Migraines can occur with or without aura. With genetic disorders, the type of mutation, or its location in the gene can sometimes be associated with varying outcomes. Yet, as for all COL4A1 mutations, no specific treatment is currently available, and, due to the variable penetrance, adapted follow-up is challenging. The surgery Endovascular therapy is a minimally-invasive procedure in which a long, thin tube called a catheter is passed into the blood vessel to repair or strengthen the blood vessel. Gould Syndrome is a rare, genetic, multi-system disorder. Dev Med Child Neurol. However, these findings can be observed independently or in combinations, in many patients with COL4A1 and COL4A2 mutations. Gould Syndrome Foundation (COL4a1/COL4A2) seeks to educate the community on the rare disease COL4A1 and it's subcategorical diagnosis'. http://www.centerwatch.com/, For information about clinical trials conducted in Europe, contact: IV-3 and IV-6 are closely followed by a neuropediatrician (VW). Thirdly, bioinformatic tools and ACMG (20) classify p.Gly743Val as likely pathogenic due to the combination of the following criteria: (i) the p.Gly743Val variant is located in a mutational hotspot/or critical and well-established functional domain, (ii) the p.Gly743Val variant is absent from controls in the Exome Sequencing Project as reported by GeneDx (30), (iii) the p.Gly743Val variant is a gene that has a low rate of benign missense variation and in which missense variants are a common mechanism of disease, (iv) the variant p.Gly743Val has been previously reported, without phenotypic description in one other report [GeneDx Accession: SCV000531635.4 Submitted: (January 29, 2019)] and from one likely pathogenic [Undiagnosed Diseases Network, NIH Accession: SCV000926981.1 Submitted: (February 21, 2019)], and (v) which multiple lines of computational evidence support a deleterious effect on the gene product (see the Bioinfromatic Interpretation of Results).
