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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 10, 2024The c.205G>A (p.A69T) alteration is located in exon 3 (coding exon 3) of the PDE9A gene. This alteration results from a G to A substitution at nucleotide position 205, causing the alanine (A) at amino acid position 69 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
