COL4A5

Associated conditions:

  • Alport syndrome

COL4A5 makes one strand of type IV collagen, a mesh that forms the kidney's filtering membrane and supports the inner ear and eye. Genetic changes in this X-linked gene are associated with Alport syndrome, with progressive kidney disease, hearing loss, and eye changes. Knowing your genetic status enables early detection and treatment to slow decline toward kidney failure.

Conditions linked to COL4A5

Alport syndrome

Alport syndrome affects collagen in the tiny filters of the kidney, and also the ears and eyes. It can cause blood in the urine, progressive kidney disease and hearing loss, so early monitoring of kidney function and blood pressure helps protect the kidneys.
