Definition of Alport syndrome
Alport syndrome is an inherited disorder that damages tiny blood vessels in the kidneys.
Causes, incidence, and risk factors
Alport syndrome is an inherited form of kidney inflammation (nephritis). It is caused by a mutation in a gene for a protein in connective tissue, called collagen.
The disorder damages the tiny blood vessels in the kidneys, called glomeruli, that filter wastes.
The goals of treatment include monitoring and controlling progression of the disease and treating the symptoms. Most important is to strictly control blood pressure.
Women usually have a normal life span with no signs of the disease except for blood in the urine. Rarely, women will have high blood pressure, swelling, and nerve deafness as a complication of pregnancy.
