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 1 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.

BP4

Computational evidence support a benign effect (MetaRNN=0.111405045).

In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant¬†is likely to be tolerated. This variant has not been reported in the literature in individuals affected with PDE2A-related conditions. This variant is present in population databases (rs754760815, gnomAD 0.007%). This sequence change replaces proline, which is neutral and non-polar, with serine, which is neutral and polar, at codon 931 of the PDE2A protein (p.Pro931Ser). -
