Molecular analysis of the cyclic AMP-dependent protein kinase A (PKA) regulatory subunit 1A (PRKAR1A) gene in patients with Carney complex and primary pigmented nodular adrenocortical disease (PPNAD) reveals novel mutations and clues for pathophysiology: augmented PKA signaling is associated with adrenal tumorigenesis in PPNAD - Groussin, L; Kirschner, L S; Vincent-Dejean, C; Perlemoine, K; Jullian, E; Delemer, B; Zacharieva, S; Pignatelli, D; Carney, J A; Luton, J P; Bertagna, X; Stratakis, C A; Bertherat, J (Am J Hum Genet, 2002)
