Disclaimer. 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. Col4a1 mutation generates vascular abnormalities correlated with Stay Informed With NORDs Email Newsletter, Launching Registries & Natural History Studies. Rouaud T, Labauge P, Lasserve ET, Mine M, Coustans M, Deburghgraeve V, et al. Orphanet: HANAC syndrome Abnormal retinal arteries are prone to rupture causing bleeding associated with temporary loss of vision or even retinal detachments that can cause permanent vision loss. Firstly, it segregates within the family with the phenotype. People listened to us and to Zeeva in a very different and proactive way. 2010;41:e513-518. Copyright 2020 Scoppettuolo, Ligot, Wermenbol, Van Bogaert and Naeije. Prenatal clinical manifestations in individuals with COL4A1/2 variants. Stroke. Unauthorized use of these marks is strictly prohibited. The COL4A2 test was negative. Neurovascular Alterations in Vascular Dementia: Emphasis on Risk Factors. Genet Med. Yet, as for all COL4A1 mutations, no specific treatment is currently available, and, due to the variable penetrance, adapted follow-up is challenging. (1987) 8:4216. This variant highlights that the COL4A1 mutation should be sought in cases of familial ophthalmologic pathologies associated with congenital porencephaly or early onset leukoencephalopathy. There is in addition a specific phenotype called HANAC with constant nephropathy, muscle cramps and frequent intracranial aneurysms. Rarely, new mutations in the gene occur in people with no history of the disorder in their family. Type IV collagen molecules attach to each other to form complex protein networks. After the COL4A1 mutation was found, systemic manifestations of COL4A1 mutations were investigated.
