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]

The c.715G>A (p.D239N) alteration is located in exon 9 (coding exon 9) of the PDE9A gene. This alteration results from a G to A substitution at nucleotide position 715, causing the aspartic acid (D) at amino acid position 239 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
