Alport syndrome is a rare, genetic form of CKD caused by mutations in the genes encoding type IV collagen, which is a major structural component of the glomerular basement membrane in the kidney. Alport syndrome affects both children and adults.Alport syndrome is a genetic condition which causes kidney disease, hearing loss, and eye abnormalities. The disease was first characterized by A. Cecil Alport, a British doctor, in 1927 and affects approximately 1 in 50,000 newborns. Alport's syndrome is caused by an abnormality in collagen in the body. Collagen is a 'building block', giving parts of the body not supported by bone their shape and strength. There is one particular type of collagen found mostly in the kidney and the ear, and this is affected in Alport's syndrome, leading to kidney failure and partial deafness.Genetic confirmation of Alport Syndrome in the subject or the family member, OR; Kidney biopsy showing glomerular basement membrane abnormalities (eg, significant thinning, thickening, irregularity or lucencies) consistent with Alport Syndrome.

Alport syndrome is an illness that causes damage to the tiny blood vessels found in kidneys and can lead to kidney disease and even kidney failure. Additionally, Alport syndrome might cause problems with the eyes and hearing loss.
