The retina is the light-sensitive membrane that lines the inside of the eyes. Some affected individuals may develop weakness or paralysis of one side of the body (hemiparesis or hemiplegia) and have seizures. Front. Brain magnetic resonance imaging (MRI) scans were carried out on a three Tesla Brain MRI (Achieva, Ingenia; Philips Healthcare, Best, The Netherlands). People with HANAC syndrome develop kidney disease (nephropathy). At 1 month of age, a neuropediatric examination disclosed normal neck muscle tonus, normal Moro reflex, bilateral placing reaction, and open hands. IV-3 had a left hemisphere porencephalic cyst and the lack of evidence of a left corticospinal tract on tractography (Figures 3E,F), IV-5 had a porencephalic cyst on the right lateral ventricle (Figure 3C), and III-3 had leukoencephalopathy (Figure 3D). The extents to which intracellular and/or extracellular insults contribute to pathology remain an open question. MedlinePlus links to health information from the National Institutes of Health and other federal government agencies. I cannot describe the feeling of seeing your child healed. 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. See our, COL4A1-related brain small-vessel disease, URL of this page: https://medlineplus.gov/genetics/condition/col4a1-related-brain-small-vessel-disease/. 2010 Oct;152A(10):2550-5. doi: 10.1002/ajmg.a.33659. doi: 10.1212/WNL.0000000000006567, PubMed Abstract | CrossRef Full Text | Google Scholar, 2.

Hereditary angiopathy with nephropathy, aneurysms, and muscle cramps (HANAC) syndrome is part of a group of conditions called the COL4A1-related disorders. MeSH The expanding phenotype of COL4A1 and COL4A2 mutations: clinical data on 13 newly identified families and a review of the literature. Jeanne M, Gould DB. 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. 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. Lecordier S, Manrique-Castano D, El Moghrabi Y, ElAli A. The two genes that code for these proteins are tightly linked on chromosome 13 and dominant COL4A1 and COL4A2 gene mutations cause a highly variable, multisystem disorder.
