Genes affected

PDE2A (HGNC:8777): (phosphodiesterase 2A) Enables several functions, including 3',5'-cyclic-nucleotide phosphodiesterase activity; anion binding activity; and metal ion binding activity. Involved in several processes, including cellular response to organic cyclic compound; cyclic-nucleotide-mediated signaling; and regulation of vascular permeability. Located in several cellular components, including cytosol; mitochondrial membrane; and perinuclear region of cytoplasm. Colocalizes with plasma membrane.

Ambry Genetics

Sep 26, 2023

The c.1422G>C (p.Q474H) alteration is located in exon 18 (coding exon 18) of the PDE2A gene. This alteration results from a G to C substitution at nucleotide position 1422, causing the glutamine (Q) at amino acid position 474 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
