Abstract

Abstract: Background: Several disease-causing genes have been implicated in Carney complex (CNC), including PRKAR1A, PDE8B (Phosphodiesterase 8B), and PDE11A (Phosphodiesterase 11A). The purpose of this study was to describe the clinical features of CNC in a Chinese patient and identify potential pathogenic mutations. Methods: Genomic DNA was extracted from the peripheral venous blood obtained from one Chinese CNC family from Shandong province. Subsequently, targeted region sequencing (TRS) and Sanger sequencing validation were performed to identify and validate likely pathogenic mutations. Results: Genetic analyses revealed a novel PDE11A variant that was predicted to lead to CNC. The patient's mother presented with the same genetic mutation. Conclusion: This study identifies new genetic mutation in CNC（PDE11A: NM_016953: exon11: c1921A>G (p./p.Lys641Glu). CNC patients presenting with subclinical Cushing's syndrome should be treated.
