Genes affected

DAPK2 (HGNC:2675): (death associated protein kinase 2) This gene encodes a protein that belongs to the serine/threonine protein kinase family. This protein contains a N-terminal protein kinase domain followed by a conserved calmodulin-binding domain with significant similarity to that of death-associated protein kinase 1 (DAPK1), a positive regulator of programmed cell death. Overexpression of this gene was shown to induce cell apoptosis. It uses multiple polyadenylation sites. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.27534175).

Dec 14, 2021

The c.1055A>T (p.E352V) alteration is located in exon 12 (coding exon 11) of the DAPK2 gene. This alteration results from a A to T substitution at nucleotide position 1055, causing the glutamic acid (E) at amino acid position 352 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
