We have recently reported that somatic mutations in the ubiquitin-specific protease 8 (USP8) are present in corticotropinomas of patients with Cushings disease and that these mutations reduced the interaction with 14-3-3. Mutant USP8 exhibited higher deubiquitination activity and potentiated EGFR-induced POMC expression (Reincke et al., Nat Genet 2014). To further study the prevalence of these mutations, we have analyzed 134 ACTH-producing corticotropin...
