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.

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 5 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

PP2

Missense variant in gene, where missense usually causes diseases (based on misZ statistic), PDE2A. . Gene score misZ 4.056 (greater than the threshold 3.09). Trascript score misZ 3.8645 (greater than threshold 3.09). GenCC has associacion of gene with intellectual developmental disorder with paroxysmal dyskinesia or seizures, infantile convulsions and choreoathetosis.

PP3

MetaRNN computational evidence supports a deleterious effect, 0.866

The c.2675G>A (p.R892H) alteration is located in exon 31 (coding exon 31) of the PDE2A gene. This alteration results from a G to A substitution at nucleotide position 2675, causing the arginine (R) at amino acid position 892 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
