Alport syndrome is a genetic condition characterized by kidney disease, hearing loss, and eye abnormalities. Most affected individuals experience progressive loss of kidney function, usually resulting in end-stage kidney disease. People with Alport syndrome also frequently develop sensorineural hearing loss in late childhood or early adolescence. The eye abnormalities seen in this condition seldom lead to vision loss. In 80% of cases, Alport syndrome is inherited in an X-linked manner and is caused by mutations in the COL4A5 gene. In the remaining cases, it may be inherited in either an autosomal recessive or autosomal dominant manner and caused by mutations in the COL4A3 or COL4A4 genes.[1] Treatment may include use of a hearing aid; hemodialysis and peritoneal dialysis to treat those with end-stage renal failure; and kidney transplantation.[2]
