col4a1 syndrome life expectancy
Neurology. A variety of additional signs and symptoms have been reported in individuals with COL4A1/A2-related disorders including childhood-onset epilepsy, hemolytic anemia (a condition characterized by low levels of circulating red blood cells due to their premature destruction leading to fatigue, weakness, lightheadedness, dizziness, irritability, headaches, and pale skin color), mitral valve prolapse (flaps of the valve located between the upper and lower left heart chambers bulge or collapse during contraction allowing leakage of blood back into the left atrium). Richards S, Aziz N, Bale S, Bick D, Das S, Gastier-Foster J, et al. Federal government websites often end in .gov or .mil. Zeeva is one of fewer than 150 people in the world with a rare disease called Gould Syndrome or COL4A1/A2. The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest. Glaucoma is initially treated with topical medications and, if medical therapy is unsuccessful, surgery. A similar term, variable expressivity, describes when affected individuals have widely varying signs and symptoms. The variability and severity of symptoms is significant and how COL4A1/A2-related disorders will potentially affect an individual can be unique. No microbleeds or cystic cavities were found. (1982) 40:5679. doi: 10.1056/NEJMoa1707914, 6. doi: 10.1016/j.matbio.2016.10.003, 23. Affected infants and children can exhibit delays in reaching developmental milestones and varying degrees of intellectual disability. Available online at: https://www.ncbi.nlm.nih.gov/clinvar/variation/VCV000389182.3 (accessed March 20, 2020). Cesarean delivery for pregnancies with fetus at risk for a COL4A1-related disorder is recommended to prevent brain vascular injury attributable to birth trauma during delivery (6). Please note that NORD provides this information for the benefit of the rare disease community. The COL4A1 gene has 52 exons and most of the pathogenic variants are distributed across exons 10 to 47 in the triple-helix domain. Breedveld G, De Coo IF, Lequin MH, Arts WFM, Heutink P, Gould DB, et al. What are the different ways a genetic condition can be inherited? The COL4A1 gene provides instructions for making one component of a protein called type IV collagen. The retina was collected and immunolabeled with an anti-collagen IV antibody, for reconstruction of the entire vascular network (Fig. Vahedi K, Alamowitch S.

Researchers are still trying to determine whether there are any specific genotype-phenotype correlations in COL4A1/A2-related disorders. This group rarely survives beyond 2 years. The causative gene of HANAC is COL4A1 (13q34) encoding the alpha1 chain of collagen IV, a major component of basement membranes also involved in . The X and Y chromosomes are called the sex chromosomes and the rest all are called 'autosomes'. . Gould Syndrome is an ultra rare genetic, multi-system disorder. Shah S, Ellard S, Kneen R, Lim M, Osborne N, Rankin J, et al. Copyright 2020 Scoppettuolo, Ligot, Wermenbol, Van Bogaert and Naeije. Zeeva woke up after a ten-hour procedure, opened her eyes, and it felt like we were seeing her for the first time. https://www.ncbi.nlm.nih.gov/pubmed/20558831, Alamowitch S, Plaisier E, Favrole P, et al. HANAC syndrome is a rare condition, although the exact prevalence is unknown. These types of correlations can be difficult to detect in patients because of the broad genetic variability in humans.

The variant was confirmed by bidirectional fluorescence DNA sequencing (Sanger method). doi: 10.1055/s-0031-1275343, 24. N Engl J Med. Research in mice with Col4a1 mutations suggests that the position of the mutation is very important. This review dsecribes the clinical spectrum of a newly identified disorder related to COL4A1 gene mutations. This can occur if the carrier is a mosaic which means that some cells carry the mutation while other cells do not. Plaisier E, Chen Z, Gekeler F, Benhassine S, Dahan K, Marro B, Alamowitch S, Paques M, Ronco P. Am J Med Genet A. Role of COL4A1 in basement-membrane integrity and cerebral small-vessel disease. COL4A1 -related brain small-vessel disease is part of a group of conditions called the COL4A1 -related disorders. Congenital Cephalic Disorders 2010 IV-5 had microcephaly without motor deficits, a language delay, a mental retardation (IQ of 62) that required adapted schooling, and severe hypermetropia. (2007) 357:268795. Other eye problems experienced by people with COL4A1-related brain small-vessel disease include clouding of the lens of the eye (cataract) and the presence of arteries that twist and turn abnormally within the light-sensitive tissue at the back of the eye (arterial retinal tortuosity). Novel mutations in three families confirm a major role of COL4A1 in hereditary porencephaly. 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. Curr Opin Neurol. Additionally, consultation with a genetic counselor is strongly recommended for affected individuals and their families and psychosocial support for the entire family is essential. Coupry I, Sibon I, Mortemousque B, Rouanet F, Mine M GC. Am J Med Genet. If neither parent carries the mutation, it is considered de novo which means that the mutation is a new occurrence. Gould Syndrome is an ultra rare genetic, multi-system disorder. 2012;54:569-574. https://www.ncbi.nlm.nih.gov/pubmed/22574627, Lanfranconi S, Markus HS. Individuals with this condition are at increased risk of having more than one stroke in their lifetime. doi: 10.1126/science.1109418, 5. Dev Med Child Neurol. However, there are exceptions that depend on precisely when and where the mutation arose. Fax: 203-263-9938, Washington, DC Office Individuals with high blood pressure (hypertension) must receive appropriate therapy because of the increased risk of stroke. (D) III- 3Brain MRI showed small asymptomatic lesions in white matter.

Compared to other COL4A1-related disorders, the brain is only mildly affected in HANAC syndrome. We believe that the variant p.Gly743Val is likely pathogenic for several reasons. 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. INTERNET 2018;61:765-772. Powered by NORD, the IAMRARE Registry Platform is driving transformative change in the study of rare disease. (2015) 88:46873. When this enzyme is elevated, it is a sign of muscle damage.

Novel COL4A1 mutations associated with HANAC syndrome: a role This is called genotype-phenotype correlation. These aneurysms have the potential to burst, causing bleeding within the brain (hemorrhagic stroke). 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. Before Epub 2022 Apr 14. NORD is not a medical provider or health care facility and thus can neither diagnose any disease or disorder nor endorse or recommend any specific medical treatments. 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). It is ubiquitously expressed in many tissues and cell types. NORD strives to open new assistance programs as funding allows. There are notable differences in the specific signs and symptoms (clinical heterogeneity), and different organs are affected to different degrees between patients even among members of a family who carry the same gene mutation. Interestingly, COL4A1 and COL4A2 mutations appear to lead to generally similar outcomes although COL4A2 mutations occur less frequently. N Engl J Med. The conditions in this group have a range of signs and symptoms that involve fragile blood vessels. Exome sequencing in 32 patients with anophthalmia/microphthalmia and developmental eye defects. In the brain, intracerebral hemorrhage is the most frequent phenotype. Other eye problems associated with HANAC syndrome include a clouding of the lens of the eye (cataract) and an abnormality called Axenfeld-Rieger anomaly. Staals J, Makin SDJ, Doubal FN, Dennis MS, Wardlaw JM. She has regular physical, speech, and occupational therapy. Clinical spectrum of type IV collagen (COL4A1) mutations: a novel 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. COL4A1/A2-Related Disorders - Symptoms, Causes, Treatment | NORD 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. 1779 Massachusetts Avenue the basement membranes surrounding the body's blood vessels, National Organization for Rare Disorders (NORD), BRAIN SMALL VESSEL DISEASE 1 WITH OR WITHOUT OCULAR ANOMALIES. Phone: 203-263-9938 It affects mainly young adults, children and more typically neonates. For example, the position of the mutation along the length of the protein can influence the severity of cerebrovascular disease and mutations in functional subdomains can influence the likelihood of tissue-specific involvement (for example, muscle). 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). Role of COL4A1 in small-vessel disease and hemorrhagic stroke. Focke JK, Veltkamp R, Bauer P, Kraemer M. J Neurol. The inheritance pattern is autosomal dominant (14) and age-dependent with almost 100% penetrance. (2020). Symptoms of the following disorders can be similar to those of COL4A1/A2-related disorders. Copyright 2023 by Gould Syndrome Foundation -, https://rarediseases.org/rare-diseases/col4a1-a2-related-disorders/. 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. Gould Syndrome - COL4A1 - COL4A2 genes - Gould Syndrome Foundation COL4A1 is a subunit of the type IV collagen and plays a role in angiogenesis. About half of people with this condition 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).

Antiinflammatory therapy with canakinumab for atherosclerotic disease. Image showed ventricular asymmetry and brain MRI confirmed right frontotemporal dilatation (B). Rarely, new mutations in the gene occur in people with no history of the disorder in their family. Internet. 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. If either parent also carries the mutation, it is considered inherited. 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%). Muscle cramps experienced by most people with HANAC syndrome typically begin in early childhood. came with risks and was the hardest decision we had ever faced, yet we felt 100 Schwarz JM, Cooper DN, Schuelke M, Seelow D.

Ten months later, the left hemiparesis was observed with a lack of voluntary prehension on his left side without spasticity. This study clearly demonstrates that COL4A1 and COL4A2 mutations cause clinically variable cerebrovascular disease that includes characteristic features of cerebral small vessel disease. No use, distribution or reproduction is permitted which does not comply with these terms. Background: COL4A1 mutations cause familial porencephaly, infantile hemiplegia, cerebral small vessel disease (CSVD), and hemorrhagic stroke. Exon mutations of the COL4A1 genes are responsible for a broad spectrum of cerebral, ocular, and systemic manifestations. It is possible that insufficient collagen in the basement membrane predisposes blood vessels in the brain to leak or rupture. The limitations include the limited number of tested members (only two generations) due to a large family spread over Europe and not fully accessible. Painful muscle cramps can occur and can develop before three years of age. Basement membranes without these networks are unstable, leading to weakening of the tissues that they surround. 2014 Mar;261(3):500-3. doi: 10.1007/s00415-013-7224-4. This variant highlights that the COL4A1 mutation should be sought in cases of familial ophthalmologic pathologies associated with congenital porencephaly or early onset leukoencephalopathy. Type IV collagen molecules attach to each other to form complex protein networks. We each inherit a full complement on autosomes from each of our parents giving us two copies of each gene. What does it mean to have a COL4A1 gene mutation: The COL4A1 gene provides instructions for making one component of type IV collagen, which is a flexible protein important in the structure of many. 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/A2-related disorders are believed to affect females and males in equal numbers. (2010) 75:7479. Contact a health care provider if you have questions about your health.

Cerebrovascular disease related to COL4A1 mutations in HANAC syndrome. Quincy, MA 02169 The cells of the retina trigger nerve impulses that run from the optic nerve to the brain to form sight. Your support helps to ensure everyones free access to NORDs rare disease reports. 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. We provide education, advocacy, and resources for families and individuals affected. Zagaglia Selch C, Nisevic JR, et al. A dominantly inherited mutation in collagen IV A1 (COL4A1) causing childhood onset stroke without porencephaly. I cannot describe the feeling of seeing your child healed. To use the sharing features on this page, please enable JavaScript. A diagnosis of COL4A1/A2-related disorders is based upon identification of characteristic symptoms, a detailed patient and family history, a thorough clinical evaluation and a variety of specialized tests including advanced imaging techniques. Other phenotypes include intracranial aneurysms, porencephaly, infantile hemiparesis, muscle cramps, optic nerve dysgenesis and secondary glaucoma. No patient had cramps, cardiac symptoms, or abnormalities or Raynaud phenomenon. 1. Type IV collagen is an important component of basement membranes in many tissues, especially blood vessels 1-6.
