Dominant genetic disorders occur when only a single copy of a non-working gene is necessary to cause a particular disease. When our 8-year-old daughter, Zeeva, giggles and runs in her walker to the swing set, its like watching pure childhood joy. Finding the best care for Zeeva - Boston Children's Answers The type IV collagens are encoded by six different genes (COL4A1, COL4A2, COL4A3, COL4A4, COL4A5 and COL4A6). Disease Overview. (2017) 377:111931. (2009) 73:187382. Image showed ventricular asymmetry and brain MRI confirmed right frontotemporal dilatation (B). Some of these patients have been described as having HANAC syndrome, which is an acronym for hereditary angiopathy, nephropathy, aneurysms, and muscle cramps. The number of genes implicated in epilepsy has grown rapidly in the past decade. Alamowitch S, Plaisier E, Favrole P, Prost C, Chen Z, Van Agtmael T, Marro B, HANAC syndrome is characterized by angiopathy, which is a disorder of the blood vessels.

COL4A1/A2-related disorders are caused by dominant mutations in the COL4A1 or COL4A2 genes. Painful muscle cramps can occur and can develop before three years of age. Stroke is often the first symptom of this condition, typically occurring in mid-adulthood. (2008) 23:17. 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. 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. came with risks and was the hardest decision we had ever faced, yet we felt 100 Liu X, Yang Q, Tang L, He J, Tian D, Wang B, Xie L, Li C, Fan D.

Early intervention is important in ensuring that children with reach their highest potential. and transmitted securely. Zeeva woke up after a ten-hour procedure, opened her eyes, and it felt like we were seeing her for the first time. Cysts can also form in one or both kidneys, and the cysts may grow larger over time. Mutations in the gene have been linked to diseases of the brain, muscle, kidney, eye, and cardiovascular system. The causative gene of HANAC is COL4A1 (13q34) encoding the alpha1 chain of collagen IV, a major component of basement membranes also involved in . Email: [emailprotected], Some current clinical trials also are posted on the following page on the NORD website: Here we report a family in which three siblings presented severe hypermetropia and porencephaly. Nearly half of these participants were diagnosed with infantile spasms. Zagaglia Selch C, Nisevic JR, et al. COL4A1/A2-Related Disorders - Symptoms, Causes, Treatment | NORD Services that may be beneficial for some affected individuals include medical, social, and/or vocational services such as special remedial education. Glaucoma is initially treated with topical medications and, if medical therapy is unsuccessful, surgery. PS and NL: followed III-3 at the Erasme Neurology outpatients clinic. This can manifest as porencephaly if the vessels rupture in utero, hemorrhagic stroke postnatally or in adults, or even small cerebral microbleeds that might go unnoticed except on MRI. Doctors and researchers to bring research and medical therapeutic options to those affected. 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. doi: mutations: a novel genetic multisystem disease. When this enzyme is elevated, it is a sign of muscle damage. 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. Volonghi I, Pezzini A, Del Zotto E, Giossi A, Costa P, Ferrari D, Padovani A. Treatment 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. Some individuals do not have any observable symptoms (asymptomatic); others can develop severe, even life-threatening complications. Porencephaly refers to the formation of fluid-filled cysts or cavities within of the brain. A dashed arrow indicates secondary atrophy in the left cerebral peduncle. In people with HANAC syndrome, angiopathy affects several parts of the body. seizure activity. Antiinflammatory therapy with canakinumab for atherosclerotic disease. II-2 had a limp since childhood attributed to forceps delivery. There are 28 different types of collagen in your body and mutations in the genes that encode these proteins lead to multiple, highly diverse diseases. Not only did Dr. Madsen, help heal Zeevas brain, but he was instrumental in supporting us as we founded the Gould Syndrome Foundation, a 501(c)(3) non-profit that promotes education, advocacy, and medical advancements in Gould Syndrome, COL4A1/COL4A2 diseases.

In the human genome, there are 46 chromosomes. Gould DB, Phalan FC, Breedveld GJ, Van Mil SE, Smith RS, Schimenti JC, et al. Drugs that prevent irregular heartbeats (anti-arrhythmic medications) are used to treat supraventricular arrythmia. 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). doi: 10.1056/NEJMoa053727, 7. The degree of mosaicism is highly variable ranging from only a small percent of cells with the mutation to nearly all cells carrying the mutation and depends on the stage during development that the mutation occurred. The conditions in this group have a range of signs and symptoms that involve fragile blood vessels. Progressive cerebral atrophies in three children with COL4A1 mutations. In some people, serious, life-threatening complications may occur in infancy; in others, only minor complications may occur and intelligence is unaffected. 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.

Any muscle may be affected, and cramps usually last from a few seconds to a few minutes, although in some cases they can last for several hours. Full ophthalmological evaluations including slit lamp and fundoscopy were realized and disclosed for bilateral hypermetropia in IV-3 [15 dioptre (D)], IV-6 (8.5 D), IV-5 (10 D), and III-3 (7 D). In cases where the mutation is inherited, the carrier parent is often clinically unaffected. Coupry I, Sibon I, Mortemousque B, Rouanet F, Mine M GC. (E,F) IV-3Brain MRI showed left frontotemporal dilatation and diffusion tensor imaging (DTI) sequences demonstrated no left corticospinal tract (cranio-caudal fibers, indigo, with arrows). Participants with epilepsy frequently reported developmental delays (88.6%), stroke (60.0%), cerebral palsy (65.7%), and constipation (57.1%). 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). Information on current clinical trials is posted on the Internet at https://clinicaltrials.gov/. doi: 10.1001/archophthalmol.2010.42, 10. . FOIA The limitations include the limited number of tested members (only two generations) due to a large family spread over Europe and not fully accessible. Novel mutations in three families confirm a major role of COL4A1 in hereditary porencephaly. Collagen alpha-1(IV) chain (COL4A1) is a protein that in humans is encoded by the COL4A1 gene on chromosome 13. doi: 10.1016/j.ejpn.2009.04.010, 27. The inheritance pattern is autosomal dominant (14) and age-dependent with almost 100% penetrance. 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.

Since fewer than 100 families have been reported, the exact prevalence of COL4A1-related disorders is not well-established. doi: 10.1212/01.WNL.0000123113.46672.68, 25. COL4A1/A2-related disorders are rare, genetic, multi-system disorders. Yet, five siblings, showing mild phenotype even in the second generation support a Mendelian transmission with variable expressivity and no other mechanism. Ten months later, the left hemiparesis was observed with a lack of voluntary prehension on his left side without spasticity. 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.

Subsequently, it has been recognized that autosomal dominant COL4A1 and COL4A2 mutations cause a broad spectrum of cerebrovascular disease, whose onset occurs from fetal life onward and whose severity may range from small-vessel disease to fatal intraparenchymal hemorrhage.,, While epilepsy is known to be a clinical feature of porencephaly, the Epilepsy and related challenges in children with COL4A1 and - PubMed Dr. Madsen suggested Zeeva have an operation called a eCollection 2021. 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. This variant highlights that the COL4A1 mutation should be sought in cases of familial ophthalmologic pathologies associated with congenital porencephaly or early onset leukoencephalopathy. Plaisier E, Ronco P. COL4A1-Related Disorders. 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). Science. The severity of the condition varies greatly among affected individuals. COL4A1 mutations as a monogenic cause of cerebral small vessel disease: a systematic review.
