We present a case of a 32-year-old female patient with juvenile onset right hand and foot dystonia and mild mental retardation due to hemorrhagic stroke associated with COL4A1 mutation. Clinical manifestations associated with mutations of the human COL4A1 gene include perinatal cerebral hemorrhage and porencephaly, hereditary angiopathy, nephropathy, aneurysms and muscle cramps (HANAC), ocular dysgenesis, myopathy, Walker-Warburg syndrome and systemic tissue degeneration. To examine how vascular defects can affect neuronal function, we analyzed the retinal phenotype of a HANAC mouse model. Specific alterations of vascular basement . The proportion of cases caused by a de novo pathogenic variant is estimated to be at least 27%. 1 The manifestations are widespread, involving the brain and eyes most commonly and other organs such as the kidneys. Background: COL4A1 is one of the components of type IV collagen. Three genes are involved in its synthesis: COL9A1, A2 and A3. GLI3 gene abnormalities can cause hypothalamic hamartoma and/or polydactyly, and Pallister Hall syndrome . AS is the most common hereditary cause of terminal renal failure. In addition to the common variants we hypothesized that rare coding variants in COL4A1 and COL4A2 could contribute to ICH . . COL4A1: Porencephaly: Cerebral small vessel disease . Diagnostic methods Laboratory investigations usually show elevated creatine kinase, myopathic/dystrophic muscle pathology with altered alpha-dystroglycan expression. It is a disease of the glomerular basement membrane (GBM) caused by homozygous or heterozygous mutation in one or, rarely, 2 . COL4A1 and COL4A2 are on Chr. Background: With increasing life expectancy and the aging population of most countries, attention to the diseases of old age has also increased. The protein encoded by this gene, GLI3 protein, is a transcription factor that controls gene expression, and is important in brain development. A mutation in the COL4A1 gene not directly related to posttranslational modification of dystroglycan has been identified in WWS patients. Further guidance on the initial work-up of these patients can be found in round 1 investigations (online supplementary table 1 in: Ahmed 1 et alJournal of Neurology, , Neurosurgery, and Psychiatry). This chapter will review the genetics, clinical manifestations, pathology, diagnosis, and treatment of each of these type IV collagen disorders.
