FAM91A1
Chr 8family with sequence similarity 91 member A1
The protein functions as a component of the WDR11 complex that facilitates golgin-mediated capture of AP-1 generated vesicles at the trans-Golgi network. This gene is highly constrained against loss-of-function variants (LOEUF 0.488), suggesting mutations would likely cause severe disease, though no specific clinical phenotypes have been established in humans yet.
