Molecular analysis was performed on a gDNA level by means of PCR amplification of all the coding exons and the flanking intron region. III-3 was asymptomatic but for severe hypermetropia and bilateral cataracts. Our review highlights that COL4A1 mutations can present for the first time in adult life with features of cerebral SVD, including subcortical hemorrhage and ischemic stroke, . Treatment If the mutation arises after fertilization, then some cells will carry the mutation and others will not this is called mosaicism. 2012;21:R97-R110. Berg's criteria was used for porencephaly (16, 17) and white matter hyperintensities were characterized as in Fazekas et al. doi: 10.1038/nmeth.2890, 22. Finding the best care for Zeeva - Boston Children's Answers COL4A1 -related brain small-vessel disease is part of a group of conditions called the COL4A1 -related disorders.

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. Accessibility Stroke. As a result, type IV collagen molecules cannot attach to each other to form the protein networks in basement membranes. Powered by NORD, the IAMRARE Registry Platform is driving transformative change in the study of rare disease. These aneurysms have the potential to burst, causing bleeding within the brain (hemorrhagic stroke). 2017 Jan;66:100-103. doi: 10.1016/j.pediatrneurol.2016.04.010. Disease Overview. 2010;41:e513-518. Mutations in COL4A1 or COL4A2 cause Gould Syndrome and, because these two proteins are found in almost all tissues; nearly any organ can be affected.
