Here, Dirk Lefeber and colleagues identify functional mutations in ATP6AP1 encoding Ac45. The authors show that Ac45 is the functional ortholog of yeast V-ATPase assembly factor Voa1 and provide evidence for tissue-specific Ac45 processing, associated with the clinical phenotype of immunodeficiency, hepatopathy, and neurocognitive abnormalities.
