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]

Uncertain significance, no assertion criteria provided	clinical testing	Department of Pathology and Laboratory Medicine, Sinai Health System	-	The PDE11A p.Arg57X variant was not identified in the literature nor was it identified in LOVD 3.0. The variant was identified in dbSNP (ID: rs76308115), Cosmic (FATHMM prediction score of neutral) and ClinVar (classified as likely benign by GeneDx and pathogenic by Genomic Research Center, Shahid Beheshti University of Medical Sciences for pigmented nodular adrenocortical disease, 2). The variant was identified in control databases in 849 of 281828 chromosomes (5 homozygous) at a frequency of 0.003012 increasing the likelihood this could be a low frequency benign variant (Genome Aggregation Database Feb 27, 2017). The variant was observed in the following populations: European (non-Finnish) in 613 of 128514 chromosomes (freq: 0.00477), Other in 26 of 7184 chromosomes (freq: 0.003619), European (Finnish) in 73 of 25042 chromosomes (freq: 0.002915), Ashkenazi Jewish in 25 of 10350 chromosomes (freq: 0.002415), South Asian in 41 of 30580 chromosomes (freq: 0.001341), Latino in 43 of 35376 chromosomes (freq: 0.001216) and African in 28 of 24956 chromosomes (freq: 0.001122); it was not observed in the East Asian population. The variant occurs outside of the splicing consensus sequence and in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer) do not predict a difference in splicing. The p.Arg57X variant leads to a premature stop codon at position 57 which is predicted to lead to a truncated or absent protein and loss of function. Other loss of function variants (c.919C>T, p.R317X) have been identified in the PDE11A gene as causal for Cushing Syndrome and ovarian cysts (Hovarth_2006_PMID: 16767104), indicating that stop gain variants in the PDE11A gene are disease-causing. Further, MutationTaster predicts the variant to be disease causing. However, this information is not predictive enough to assume pathogenicity. In summary, based on the above information the clinical significance of this variant cannot be determined with certainty at this time. This variant is classified as a variant of uncertain significance. -
