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.
