The renal lesions of Alport syndrome.
Alport syndrome is a hereditary, progressive, hematuric nephropathy characterized by glomerular basement membrane abnormalities with frequent hearing defects and ocular anomalies. The disease is associated with mutations in genes encoding the alpha3, alpha4, or alpha5 chains of type IV collagen, COL4A3, or COL4A4 in the autosomal forms of the disease, COL4A5 in the more frequent X-linked variet...
متن کاملAlport Syndrome
A.K. was a 5-year-old boy who presented to the pediatric nephrology clinic with a recent finding of microscopic hematuria and proteinuria on routine screening. The analysis was repeated two weeks later with persistence of hematuria and proteinuria. A complete blood count (CBC) and a metabolic panel (Chem7) were both normal. Renal ultrasound was performed which was also normal and without hydron...
متن کاملDiagnosis of Alport syndrome
chain altered distribution in a much higher proportion of patients with X-linked AS [5]. It is our experience that skin biopsy, examined with conventional, and if needed, with confocal microscopy, is able to virtually detect (almost) all cases of X-linked AS [5], thus allowing to avoid or to postpone more invasive and/or expensive diagnostic procedure like renal biopsy and genetic investigation...
متن کاملX-linked Alport syndrome
X-linked Alport syndrome (AS) is a heritable disorder which is associated with mutations in the type IV collagen oc5(IV) chain gene (COL4A5) located on chromosome X. Following renal transplantation, an average of 6% of male AS patients develop anti-GBM nephritis. We studied the specificity of the antibodies against type IV collagen in the serum of a patient with COL4A5 partial deletion. The spe...
متن کاملAlport syndrome: clinical update.
This review of the literature on Alport syndrome (AS) places emphasis on genetic and clinical issues related to the sensorineural hearing loss in type III and type IV X-linked AS. The review covers prevalence, medical issues, genetic issues, audiologic findings, vestibular findings, the pathophysiology of hearing loss in type III AS, age- and phenotype-specific normative data and concludes with...
