Collagen type IV, alpha 6

This gene encodes a collagen component of basement membranes localized mainly in the glomerular basement membrane and mucous membrane, so from mutations results both leiomyomatosis (smooth muscle tumors) and Alport syndrome.

Genetests:

Clinic Method Multiplex Ligation-Dependent Probe Amplification
