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.) Curr Opin Neurol. Comparisons may be useful for a differential diagnosis: CADASIL is a rare genetic disorder affecting the small blood vessels in the brain. Summary. doi: 10.1136/jmg.2005.035584, 15. 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. Children with the most severe brain malformations may have: Intellectual impairment Seizures Hydrocephalus Spasticity People who have a disorder of the corpus callosum typically have: Here we report a family in which three siblings presented severe hypermetropia and porencephaly. Surgery or endovascular therapy can be used to treat intracranial hemorrhage. The retina was collected and immunolabeled with an anti-collagen IV antibody, for reconstruction of the entire vascular network (Fig. 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. HANAC syndrome is a rare condition, although the exact prevalence is unknown. 2018;91:e2078-e2088. All studies receiving U.S. Government funding, and some supported by private industry, are posted on this government web site. Prenatal clinical manifestations in individuals with COL4A1/2 variants. Zeeva woke up after a ten-hour procedure, opened her eyes, and it felt like we were seeing her for the first time. Figure 3. Arch Neurol. However, in people with HANAC syndrome, these aneurysms typically do not burst. Suite 310 U.S. Department of Health and Human Services, Autosomal dominant familial hematuria, retinal arteriolar tortuosity, contractures, Hereditary angiopathy with nephropathy, aneurysm, and muscle cramps syndrome. Years published: 2019. Probands' father had severe hypermetropia and bilateral cataracts. 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).

Dominant genetic disorders occur when only a single copy of a non-working gene is necessary to cause a particular disease. Childhood presentation of COL4A1 mutations. Danbury, CT 06810 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). Vahedi K, Alamowitch S. Clinical spectrum of type IV collagen (COL4A1) Breedveld G, De Coo IF, Lequin MH, Arts WFM, Heutink P, Gould DB, et al. Other phenotypes include intracranial aneurysms, porencephaly, infantile hemiparesis, muscle cramps, optic nerve dysgenesis and secondary glaucoma. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3459649/, Federico A, Di Donato I, Bianchi S, et al.

We described the phenotype associated to a likely pathogenic variant of the COL4A1 gene (c.2228G>T, p.Gly743Val) responsible for severe hypermetropia and familial porencephaly. CADASIL is an acronym that stands for: (C)erebral relating to the brain (A)utosomal (D)ominant a form of inheritance in which one copy of an abnormal gene is necessary for the development of a disorder (A)rteriopathy disease of the arteries (blood vessels that carry blood away from the heart) (S)ubcortical relating to specific areas of the brain supplied by deep small arteries (I)nfarcts tissue loss in the brain caused by lack of blood flow to the brain, which occurs when circulation through the small arteries is severely reduced or interrupted (L)eukoencephalopathy lesions in the brain white matter caused by the disease and observed on MRI. I cannot describe the feeling of seeing your child healed. 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%). Bethesda, MD 20894, Web Policies These types of correlations can be difficult to detect in patients because of the broad genetic variability in humans. 2014 Mar;261(3):500-3. doi: 10.1007/s00415-013-7224-4. In: Pagon RA, Bird TD, Dolan CR, et al., GeneReviews. doi: 10.1056/NEJMoa1707914, 6. The information on this site should not be used as a substitute for professional medical care or advice. Until just this year, her 16-year-old daughter Emily, who #1 Ranked Childrens Hospital by U. S. News & World Report. doi: 10.1007/s10897-008-9169-9, 16. National Center for Biotechnology Information. Aura refers to additional neurological symptoms that occur with, or sometimes before, the development of the migraine headache. Gould Syndrome is diagnosed following a genetic test revealing a mutation in COL4A1 or COL4A2. National Institute of Neurological Disorders and Stroke. The expanding phenotype of COL4A1 and COL4A2 mutations: clinical data on 13 newly identified families and review of the literature. for the triple helical CB3[IV] domain. I dont think we will ever be able to truly articulate our appreciation for Dr. Madsen and Boston Childrens for all that they did for Zeeva and our family. Our data testing the effects of established mutations on collagen biosynthesis suggest that the intracellular retention of mutant COL4A1 proteins at the expense of their secretion appears to be a common effect of many COL4A1 mutations. Genotype-phenotype correlations in pathology caused by collagen type IV alpha 1 and 2 mutations. The variant was confirmed by bidirectional fluorescence DNA sequencing (Sanger method). Another limitation is the systemic work-up based on described phenotypes and supposed affected organs.

When a mutation occurs in one of these genes, the rope does not wind up properly and it stays inside the cell. What does it mean if a disorder seems to run in my family? (2008) 23:17. The expanding phenotype of COL4A1 and COL4A2 mutations: clinical data on 13 newly identified families and a review of the literature. mutation in Axenfeld-Rieger anomaly with leukoencephalopathy and stroke. In addition the whole spectrum of the phenotype is not yet known and there are many asymptomatic patients. https://www.ncbi.nlm.nih.gov/pubmed/20558831, Alamowitch S, Plaisier E, Favrole P, et al. Some individuals do not have any observable symptoms (asymptomatic); others can develop severe, even life-threatening complications. 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. Arterial retinal tortuosity can cause episodes of bleeding within the eye following any minor trauma to the eye, leading to temporary vision loss. Fax: 203-263-9938, Washington, DC Office 2022 Sep;269(9):5153-5156. doi: 10.1007/s00415-022-11111-0. doi: 10.1038/nmeth.2890, 22. 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 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. Various muscles can be affected and muscle strength can become weakened. Changing lives of those with rare disease. Vahedi K, Alamowitch S. Clinical spectrum of type IV collagen (COL4A1) COL4A1 Mutation in a Neonate With Intrauterine Stroke and Anterior Segment Dysgenesis.

The COL4A1 gene mutations that cause COL4A1-related brain small-vessel disease result in the production of a protein that disrupts the structure of type IV collagen. COL4A1/A2-related disorders are dominant genetic disorders. Neurol. 128:4839. 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. 4 Both .
