Two families with novel missense mutations in COL4A1: When diagnosis can be missed.
Torino, Italy. In J Neurol Sci, 15 Jun 2015
Mutations in COL4A1, encoding one of the six collagen type IV proteins, cover a wide spectrum of autosomal dominant overlapping phenotypes including porencephaly, small-vessel disease and hemorrhagic stroke, leukoencephalopathy, hereditary angiopathy with nephropathy, aneurysms and muscle cramp (HANAC) syndrome, and Walker-Warburg syndrome.
Extracellular matrix remodeling and its contribution to protective adaptation following lengthening contractions in human muscle.
Provo, United States. In Faseb J, 25 Apr 2015
Expression of collagen I, III, and IV (COL1A1, COL3A1, COL4A1) transcripts was unchanged early but increased 5.7 ± 2.5-, 3.2 ± 0.9-, and 2.1 ± 0.4-fold (P < 0.05), respectively, 27 days post-B1 and were unaffected by B2.
Genetics of cerebral small vessel disease.
Cheju, South Korea. In J Stroke, Jan 2015
These include cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy, cerebral autosomal recessive arteriopathy with subcortical infarcts and leukoencephalopathy, COL4A1-related cerebral SVD, autosomal dominant retinal vasculopathy with cerebral leukodystrophy, and Fabry disease.
Association of genetic variants with diabetic nephropathy.
Lucknow, India. In World J Diabetes, Jan 2015
The risk of developing diabetic nephropathy is increased several times by inheriting risk alleles at susceptibility loci of various genes like ACE, IL, TNF-α, COL4A1, eNOS, SOD2, APOE, GLUT, etc.
Gene expression profile analyze the molecular mechanism of CXCR7 regulating papillary thyroid carcinoma growth and metastasis.
Shenyang, China. In J Exp Clin Cancer Res, Dec 2014
More importantly, the expression level of genes closely associated with tumor growth and metastasis was altered significantly in K1-CXCR7 cells, including up-regulated genes FN1, COL1A1, COL4A1, PDGFRB, LTB, CXCL12, MMP-11, MT1-MMP and down-regulated genes ITGA7, and Notch-1.
Molecular basis of young ischemic stroke.
Milano, Italy. In Curr Med Chem, 2012
This article reviews the existing literature on the most investigated monogenic disorders (CADASIL, Fabry disease, MELAS, RVCL, COL4A1, Marfan and Ehlers-Danlos syndromes) causing stroke in young and a number of candidate genes associated with stroke occurring in patients younger than 50 years.
Childhood presentation of COL4A1 mutations.
Bristol, United Kingdom. In Dev Med Child Neurol, 2012
COL4A1 mutations can present in children with infantile hemiplegia/quadriplegia, stroke or epilepsy, and a motor disorder.
Role of COL4A1 in small-vessel disease and hemorrhagic stroke.
Bar Harbor, United States. In N Engl J Med, 2006
Identified a COL4A1 mutation in a human family with small-vessel disease. Mutation of COL4A1 may cause a spectrum of cerebrovascular phenotypes and that persons with COL4A1 mutations may be predisposed to hemorrhage.
