Alport syndrome: Kidney Involvement Hearing Loss and Ocular Abnormalities
Alport syndrome is a rare genetic disorder that primarily affects the kidneys, ears, and eyes. It is characterized by progressive kidney disease, hearing loss, and sometimes eye abnormalities. This syndrome is caused by mutations in genes that encode for proteins found in the basement membrane of the glomerulus, which is a crucial component of the kidney's filtering system. Here are some key features and aspects of Alport syndrome: Kidney Involvement: The most common and significant manifestation of Alport syndrome is kidney disease. It often presents as hematuria (blood in the urine) during childhood. Over time, this can progress to proteinuria (excessive protein in the urine) and eventually result in chronic kidney disease and end-stage renal disease (ESRD). Kidney transplantation or dialysis may be necessary for those with ESRD. Hearing Loss: Sensorineural hearing loss, typically high-frequency hearing loss, is another common feature of Alport syndrome. This hearing impairment c...
