Genes affected

PDE11A (HGNC:8773): (phosphodiesterase 11A) The 3',5'-cyclic nucleotides cAMP and cGMP function as second messengers in a wide variety of signal transduction pathways. 3',5'-cyclic nucleotide phosphodiesterases (PDEs) catalyze the hydrolysis of cAMP and cGMP to the corresponding 5'-monophosphates and provide a mechanism to downregulate cAMP and cGMP signaling. This gene encodes a member of the PDE protein superfamily. Mutations in this gene are a cause of Cushing disease and adrenocortical hyperplasia. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

The p.Thr58ProfsX41 variant in PDE11A has been reported in 1 individual with adrenocortical hyperplasia and Cushing syndrome, and segregated with disease in 1 parent with hypertension, obesity, and bilaterally enlarged adrenal glands (Horvath 2006). This variant has also been reported in 1 individual with acromegaly (Peverelli 2009) and in 3 individuals with Carney complex who also carried PRKAR1A variants, and was considered to be a possible modifier of disease in these individuals (Libe 2011). The p.Thr58ProfsX41 variant is predicted to cause a frameshift, which alters the protein’s amino acid sequence beginning at position 58 and leads to a premature termination codon 41 amino acids downstream. This alteration is then predicted to lead to a truncated or absent protein. Several loss-of-function PDE11A variants have been described in individuals with Cushing syndrome and with adrenal hyperplasia with established loss-of-heterozygosity in somatic tissue (Horvath 2006, Carney 2010, Libe 2011). However, this variant has been identified in 4% (647/16342; 17 homozygotes) of South Asian chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org) calling into question the validity of a pathogenic interpretation and leaving the clinical significance of the p.Thr58ProfsX41 variant as uncertain. -

Review Status: criteria provided, single submitter

Collection Method: research

The c.171delT variant in PDE11A has been identified in 6 individuals with possible adrenocortical hyperplasia (PMID: 16767104, 19671705, 20351491, 21047926), and has been identified in >3% of South Asian chromosomes and 18 homozygotes by ExAC (http://gnomad.broadinstitute.org/). In summary, although additional studies are required to fully establish its clinical significance, this variant meets criteria to be classified as likely benign for adrenocortical hyperplasia. -
