Oral expression was reduced and neuropsychological testing revealed language delay with a prominent expression deficit. Neurologic phenotypes associated with COL4A1/2 mutations: expanding the spectrum of disease. (2009) 73:187382. COL4A1 Syndrome CADASIL Rare disorders often go misdiagnosed or undiagnosed, making it difficult to determine their true frequency in the general population. How are genetic conditions treated or managed? We describe here the phenotype of a likely pathogenic gene variant, p.Gly743Val, which is responsible for a missense mutation in the COL4A1 gene exon 30 in a three generation family with severe hypermetropia and highly penetrant porencephaly in the absence of systemic manifestations. Acute urinary retention due to a novel collagen COL4A1 mutation. Powered by NORD, the IAMRARE Registry Platform is driving transformative change in the study of rare disease. Novel mutations in three families confirm a major role of COL4A1 in hereditary porencephaly. Similar blood vessel weakness and breakage occurs in the eyes of some affected individuals. Eur J Med Genet. 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. Role of COL4A1 in basement-membrane integrity and cerebral small-vessel disease. We provide education, advocacy, and resources for families and individuals affected. What are the different ways a genetic condition can be inherited? Childhood presentation of COL4A1 mutations. Dr. Joseph Madsen was as wonderful in person as he had been on the phone. These exceptions are nuanced and should be discussed with a genetic counselor. [Hereditary angiopathy with nephropathy, aneurysms and muscle cramps (HANAC): a new basement membrane-disease associated with mutations of the COL4A1 gene]. Your support helps to ensure everyones free access to NORDs rare disease reports. COL4A1 mutations as a monogenic cause of cerebral small vessel disease: a systematic review. 2010 Aug;41(8):e513-8. As a result, type IV collagen molecules cannot attach to each other to form the protein networks in basement membranes. 8600 Rockville Pike (2008) 23:17. These types of correlations can be difficult to detect in patients because of the broad genetic variability in humans. He smiled, caught it, and asked Zeeva if he could throw it back. In addition the whole spectrum of the phenotype is not yet known and there are many asymptomatic patients. Childhood presentation of COL4A1 mutations. This raises questions about what tests Liliane has a lot to be grateful for this holiday season. MedlinePlus also links to health information from non-government Web sites. Hereditary angiopathy with nephropathy, aneurysms, and muscle cramps (HANAC) syndrome is part of a group of conditions called the COL4A1-related disorders.

Slavotinek AM, Garcia ST, Chandratillake G, Bardakjian T, Ullah E, Wu D, et al. 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. doi: 10.1126/science.1109418, 5. Clin Neurol Neurosurg. If the mutation arises after fertilization, then some cells will carry the mutation and others will not this is called mosaicism. We therefore began our analysis of mutant Col4a1 G498V mice by examining the retinal vascular network at three and nine months of age. Gould Syndrome is an ultra rare genetic, multi-system disorder. functional hemispherectomy. It is possible that insufficient collagen in the basement membrane predisposes blood vessels in the brain to leak or rupture. 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. Novel heterozygous COL4A2 variant c.2572A>G, p.(I858V) mimicking Sneddon's and Divry van Bogaert Syndrome. percent confident in Dr. Madsen and the epilepsy team. Fragile or damaged blood vessels or basement membranes in the kidneys can lead to blood in the urine (hematuria). The COL4A1 gene mutations that cause HANAC syndrome result in the production of a protein that disrupts the structure of type IV collagen. 2008 May;192(5):971-84; discussion 984-6. Researchers are still trying to determine whether there are any specific genotype-phenotype correlations in COL4A1/A2-related disorders.

Individuals with high blood pressure (hypertension) must receive appropriate therapy because of the increased risk of stroke. Thats not to say Zeeva hasnt had to work hard since the surgery. (2010) 75:7479. Neurology. 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. The COL4A1 gene has 52 exons and most of the pathogenic variants are distributed across exons 10 to 47 in the triple-helix domain. Common variation in COL4A1/COL4A2 is associated with sporadic cerebral small vessel disease. The networks formed by the COL4A1 and COL4A2 proteins are called basement membranes and are present in every organ of the body. Jeanne M, Gould DB. N Engl J Med. 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.

COL4A1/A2-related disorders are rare, genetic, multi-system disorders. Curr Med Chem. 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). Clinical case reports suggest a syndrome with characteristic core findings; however, much about the disorder is not fully understood. 1. Neurology. For example, networks of COL4A1 and COL4A2 are present in the basement membranes of blood vessels. doi: 10.1007/s00417-014-2800-6, 12. 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 expressivity of the disease is highly variable with high intra- and inter-familial variability (2). Washington, DC 20036 Due to the rarity of the disease, there are no treatment trials that have been tested on a large group of patients. Various treatments have been reported in the medical literature as part of single case reports or small series of patients. cutting tissue called the corpus callosum, then make some additional delicate The severity of the condition varies greatly among affected individuals. The extents to which intracellular and/or extracellular insults contribute to pathology remain an open question. doi: 10.1111/j.1469-8749.2011.04198.x, 26. (18) and Staals et al. INTERNET Novel COL4A1 mutations associated with HANAC syndrome: a role for the triple helical CB3[IV] domain. Hereditary angiopathy with nephropathy, aneurysms, and muscle cramps (HANAC) syndrome is part of a group of conditions called the COL4A1 -related disorders. 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. The COL4A1 gene provides instructions for making one component of a protein called type IV collagen. Standardized human pedigree nomenclature: update and assessment of the recommendations of the National Society of Genetic Counselors. 2018;91:e2078-e2088. 2010;41:e513-518.

There is in addition a specific phenotype called HANAC with constant nephropathy, muscle cramps and frequent intracranial aneurysms. Compared to other COL4A1-related disorders, the brain is only mildly affected in HANAC syndrome. In most people, small vessel disease in the brain does not cause symptoms. doi: 10.1056/NEJMoa053727, 7. Before Gould Syndrome Foundation (COL4a1/COL4A2) seeks to educate the community on the rare disease COL4A1 and it's subcategorical diagnosis'. Zeeva woke up after a ten-hour procedure, opened her eyes, and it felt like we were seeing her for the first time. These disorders include autosomal dominant retinal vasculopathy with cerebral leukodystrophy (RVCL), hereditary endotheliopathy with retinopathy, nephropathy, and stroke (HERNS), cerebral autosomal recessive arteriopathy with subcortical infarcts and leukodystrophy (CARASIL), mitochondrial encephalopathy, lactic acidosis, and stroke-like episodes (MELAS), Fabry disease, and a variety of leukodystrophies, rare progressive metabolic disorders that affect the brain, spinal cord and often the peripheral nerves. The first reports of human COL4A1 mutations were in patients with autosomal dominant porencephaly and a more recent study found that COL4A1 mutations were found in ~16% of patients with porencephaly. N Engl J Med. Berg's criteria was used for porencephaly (16, 17) and white matter hyperintensities were characterized as in Fazekas et al. Some individuals with COL4A1-related brain small-vessel disease do not have any signs or symptoms of the condition. 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. The COL4A1 stroke 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. came with risks and was the hardest decision we had ever faced, yet we felt 100 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. 2018;61:765-772. Plaisier E, Ronco P. COL4A1-Related Disorders. COL4A1-related brain small-vessel disease is part of a group of conditions called the COL4A1-related disorders. Some may only develop specific symptoms such as isolated migraines or strokes in childhood or adulthood. Ronco P. Cerebrovascular disease related to COL4A1 mutations in HANAC syndrome. Mutated patients develop a diffuse small vessel disease of the brain as shown by a diffuse leukoencephalopathy on MRI. 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. 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 expanding phenotype of COL4A1 and COL4A2 mutations: clinical data on 13 newly identified families and review of the literature. Figure 3. Neurology. Facebook: https://www.facebook.com/Col4A1Foundation Please Note Vilain C, Van Regemorter N, Verloes A, David P, Van Bogaert P. Neuroimaging fails to identify asymptomatic carriers of familial porencephaly. In the eye, patients may have retinal arteriolar tortuosities and retinal hemorrhages or anterior segment dysgenesis. After the COL4A1 mutation was found, systemic manifestations of COL4A1 mutations were investigated. These genes are the blueprints for two proteins that wind together like a long rope inside cells. She, then, developed seizures which were controlled by valproic acid. ClinVar; [VCV000389182.3]. COL4A1 Mutation in a Neonate With Intrauterine Stroke and Anterior Segment Dysgenesis. The outcomes are highly variable ranging from brain hemorrhage before birth (in utero) leading to cavities in the brain (porencephaly) to mild age-related brain abnormalities that can only be observed on a specialized x-ray called magnetic resonance imaging (MRI). Sci Rep. 2016;6:18602. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4728690/, Rannikmae K, Davies G, Thomson PA, et al. doi: 10.1001/archneur.1983.04050080067013, 17. 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). Front. We recently described hereditary angiopathy with nephropathy, aneurysm, and muscle cramps (HANAC) syndrome in 3 families with closely localized COL4A1 mutations. In some people, serious, life-threatening complications may occur in infancy; in others, only minor complications may occur and intelligence is unaffected. Because the collagen is found throughout the body, COL4A1/A2 affects many organ systems, including the brain, kidneys, eyes, and muscles. The signs and symptoms can manifest at almost any age from before birth to old age.
