Genes affected
PDE9A (HGNC:8795): (phosphodiesterase 9A) The protein encoded by this gene catalyzes the hydrolysis of cAMP and cGMP to their corresponding monophosphates. The encoded protein plays a role in signal transduction by regulating the intracellular concentration of these cyclic nucleotides. Multiple transcript variants encoding several different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 07, 2022The c.352C>T (p.R118W) alteration is located in exon 5 (coding exon 5) of the PDE9A gene. This alteration results from a C to T substitution at nucleotide position 352, causing the arginine (R) at amino acid position 118 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
