If either parent also carries the mutation, it is considered inherited. Neurovascular Alterations in Vascular Dementia: Emphasis on Risk Factors. In: Pagon RA, Bird TD, Dolan CR, et al., GeneReviews. 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). Quincy, MA 02169 Over 100 families have been identified with these disorders in the medical literature and many more cases are known that are not in the published literature. Because the collagen is found throughout the body, COL4A1/A2 affects many organ systems, including the brain, kidneys, eyes, and muscles. Hum Mol Genet. Genet Med. COL4A1/COL4A2 gene mutations description, symptoms and the sub-diagnosis. 2009 Dec 1;73(22):1873-82. doi: 10.1212/WNL.0b013e3181c3fd12. Thats not to say Zeeva hasnt had to work hard since the surgery. We believe that the variant p.Gly743Val is likely pathogenic for several reasons. How can gene variants affect health and development? doi: 10.1212/WNL.0b013e3181eee440, 28. MedlinePlus links to health information from the National Institutes of Health and other federal government agencies. Vahedi K, Alamowitch S. Clinical spectrum of type IV collagen (COL4A1) 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). Unauthorized use of these marks is strictly prohibited. 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. Internet. (2012) 54:56974. Hereditary angiopathy with nephropathy, aneurysms, and muscle cramps (HANAC) syndrome is part of a group of conditions called the COL4A1 -related disorders. Compared to other COL4A1-related disorders, the brain is only mildly affected in HANAC syndrome. Summary. Aguglia U, Gambardella A, Breedveld GJ, Oliveri RL, Le Piane E, Messina D, et al. Various treatments have been reported in the medical literature as part of single case reports or small series of patients. 2022 Sep;269(9):5153-5156. doi: 10.1007/s00415-022-11111-0.

Accessibility 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 causative gene of HANAC is COL4A1 (13q34) encoding the alpha1 chain of collagen IV, a major component of basement membranes also involved in . Please enable it to take advantage of the complete set of features! Novel heterozygous COL4A2 variant c.2572A>G, p.(I858V) mimicking Sneddon's and Divry van Bogaert Syndrome. Neurologic phenotypes associated with COL4A1/2 mutations: expanding the spectrum of disease. It looks like nothing was found at this location. 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). For the nucleotide numbering, the HVGS terms (www.hgvs.org) were applied with the nucleotide A of the ATG startcodon = c.1. COL4A1 -related brain small-vessel disease is part of a group of conditions called the COL4A1 -related disorders. The networks formed by the COL4A1 and COL4A2 proteins are called basement membranes and are present in every organ of the body. What is the prognosis of a genetic condition? 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. For example, if the mutation arises during the formation of the sperm or the egg, then all of the cells that make up the child will carry the mutation. Individuals with this condition are at increased risk of having more than one stroke in their lifetime. PMC PV and VW followed the children at the Neuropediatrics clinic of the same hospital. Maybe try a search? 2010 Oct;152A(10):2550-5. doi: 10.1002/ajmg.a.33659. Clin Neurol Neurosurg. [Hereditary angiopathy with nephropathy, aneurysms and muscle cramps (HANAC): a new basement membrane-disease associated with mutations of the COL4A1 gene]. Participants with epilepsy frequently reported developmental delays (88.6%), stroke (60.0%), cerebral palsy (65.7%), and constipation (57.1%). View CNBC interview with NORDs Peter Saltonstall and Boston Childrens Dr. Olaf Bodamer emphasizing the importance of investment in rare diseases. She has regular physical, speech, and occupational therapy. Pediatricians are physicians who specialize in the childhood disorders and are often the first to detect patients with COL4A1/A2-related disorders. If neither parent carries the mutation, it is considered de novo which means that the mutation is a new occurrence. Phone: 203-263-9938 The X and Y chromosomes are called the sex chromosomes and the rest all are called 'autosomes'. N Engl J Med. Cysts can also form in one or both kidneys, and the cysts may grow larger over time. Systemic work-up including renal function, CK levels, urinary sediment test, and renal ultrasound proved unremarkable.

(D) III- 3Brain MRI showed small asymptomatic lesions in white matter. Drugs that prevent irregular heartbeats (anti-arrhythmic medications) are used to treat supraventricular arrythmia. It affects mainly young adults, children and more typically neonates. (For more information on these disorders, choose the specific disorder name as your search term in the Rare Disease Database.). Fax: 203-263-9938, Washington, DC Office COL4A1 codes for extracellular matrix proteins that form heterotrimers that are major components of nearly all organ basal membranes. Some affected individuals may develop weakness or paralysis of one side of the body (hemiparesis or hemiplegia) and have seizures. January 31, 2019 Alamowitch S, Plaisier E, Favrole P, Prost C, Chen Z, Van Agtmael T, et al. 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). Acute urinary retention due to a novel collagen COL4A1 mutation. 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. Suite 500 Graefe's Arch Clin Exp Ophthalmol. Ann Until just this year, her 16-year-old daughter Emily, who #1 Ranked Childrens Hospital by U. S. News & World Report. 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. 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. COL4A1/A2-related disorders are caused by dominant mutations in the COL4A1 or COL4A2 genes. National Center for Biotechnology Information. Nat Methods. In the front of the eye, patients can have abnormally small eyes (microphthalmia), cataracts (cloudy lenses), and anterior segment dysgenesis (Axenfeld-Rieger). Background: COL4A1 mutations cause familial porencephaly, infantile hemiplegia, cerebral small vessel disease (CSVD), and hemorrhagic stroke.

Fetal origin of brain damage in 2 infants with a COL4A1 mutation: fetal and neonatal MRI. It is passed through families in a autosomal dominant fashion. Zagaglia S, Selch C, Nisevic JR, Mei D, Michalak Z, Hernandez-Hernandez L, et al. 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. 2022 Mar 24;3:100140. doi: 10.1016/j.cccb.2022.100140. How are genetic conditions treated or managed? 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. Contact a health care provider if you have questions about your health. We therefore began our analysis of mutant Col4a1 G498V mice by examining the retinal vascular network at three and nine months of age. This raises questions about what tests Liliane has a lot to be grateful for this holiday season. Neuropediatrics. mutations: a novel genetic multisystem disease. 30. Volonghi I, Pezzini A, Del Zotto E, Giossi A, Costa P, Ferrari D, Padovani A. 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. Am J Med Genet A. Secondly, the p.Gly743Val variant is a missense mutation that shares features with other missense pathogenic mutations that occur in the COL4A1 gene exon 30: congenital porencephaly, epilepsy, and neuropsychological anomalies in p.Gly749Ser (23, 24), ophthalmologic defects and neuropsychological deficits in absence of systemic signs in variant p.Gly755Arg (2527), and antenatal fetal intracerebral hemorrhage, ocular anomalies associated to cerebral leukoencephalopathy in variant p.Gly773Arg (12, 28, 29). The COL4A1 and COL4A2 genes were screened in proband IV-6. Novel mutations in three families confirm a major role of COL4A1 in hereditary porencephaly. 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. No ophthalmological surgery was planned on annual control for any member, but only positive lens correction prescribed. 1779 Massachusetts Avenue Pathology. Epub 2016 Apr 24. Bull Acad Natl Med. There are no standardized treatment protocols or guidelines for affected individuals. The ultimate goal of IAMRARE is to unite patients and research communities in the improvement of care and drug development. 8600 Rockville Pike Washington, DC 20036 Phone: 202-588-5700. Muscle cramps can be spontaneous or triggered by exercise. It is possible that insufficient collagen in the basement membrane predisposes blood vessels in the brain to leak or rupture. Brain magnetic resonance imaging (MRI) scans were carried out on a three Tesla Brain MRI (Achieva, Ingenia; Philips Healthcare, Best, The Netherlands). ), A variety of rare genetic disorders may have symptoms similar to those found in COL4A1/A2-related disorders. (2014) 83:122834. Lanfranconi S, Markus HS. Information on current clinical trials is posted on the Internet at https://clinicaltrials.gov/. When these ropes are secreted, they assemble into net-like structures outside the cells. Neurology. COL4A1 mutations as a monogenic cause of cerebral In the brain, intracerebral hemorrhage is the most frequent phenotype. While muscle cramps may begin in childhood, many of the other symptoms do not appear until later in life. Epub 2010 Jun 17. For example, an individual may carry genetic variants elsewhere in their genome that confers protection or susceptibly to the mutation and environmental experiences (trauma, anticoagulant use, physical exertion etc.) 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. doi: 10.2214/ajr.149.2.351, 19. Autosomal Dominant Brain Small Vessel Disease. Exome sequencing in 32 patients with anophthalmia/microphthalmia and developmental eye defects. doi: 10.1111/cge.12379, 13.

Matrix Biol. 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 strengths of our study are the extensive systemic work-up, the 5-year neurological follow-up, and the pluridisciplinary approach. (2017) 5758:2944. Ann Neurol. The prevalence of HANAC syndrome (hereditary angiopathy-nephropathy-aneurysms-muscle cramps syndrome) is not available, but at least six affected families have been reported worldwide to date. Genet Med. For asymptomatic patients, cerebral and vessel imaging for aneurysm screening and ophthalmologic follow-up are indicated (2). Novel COL4A1 mutations associated with HANAC syndrome: a role for the triple helical CB3[IV] domain. People listened to us and to Zeeva in a very different and proactive way. The conditions in this group have a range of signs and symptoms that involve fragile blood vessels. (2004) 62:16135. COL4A1/A2-related disorders can also be associated with a variety of abnormalities affecting the front or back of the eyes. COL4A1 may be a candidate gene in unexplained familial syndromes with autosomal dominant hematuria, cystic kidney disease, intracranial aneurysms, and muscle cramps. 2010;41:e513-518. MedlinePlus links to health information from the National Institutes of Health and other federal government agencies. Staals J, Makin SDJ, Doubal FN, Dennis MS, Wardlaw JM. 2011 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). Careers. Neurology. Cereb Circ Cogn Behav. Standardized human pedigree nomenclature: update and assessment of the recommendations of the National Society of Genetic Counselors. Zeeva is one of fewer than 150 people in the world with a rare disease called Gould Syndrome or COL4A1/A2.
