Genes affected

DAPK1 (HGNC:2674): (death associated protein kinase 1) Death-associated protein kinase 1 is a positive mediator of gamma-interferon induced programmed cell death. DAPK1 encodes a structurally unique 160-kD calmodulin dependent serine-threonine kinase that carries 8 ankyrin repeats and 2 putative P-loop consensus sites. It is a tumor suppressor candidate. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2013]

The c.834A>C (p.K278N) alteration is located in exon 10 (coding exon 9) of the DAPK1 gene. This alteration results from a A to C substitution at nucleotide position 834, causing the lysine (K) at amino acid position 278 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
