Kollagen Typ IV, alpha 2
Das COL4A2-Gen kodiert eine Kollagen-alpha-Kette, die in fast allen Basalmembranen zu finden ist. Es wird gemeinsam mit COL4A1 exprimiert und deshalb finden sich auch pathogenetische Mutationen bei den gleichen Erkrankungen: Porenzephalie, Small-vessel disease und Schlaganfall.
