Genes affected

MAPK4 (HGNC:6878): (mitogen-activated protein kinase 4) Mitogen-activated protein kinase 4 is a member of the mitogen-activated protein kinase family. Tyrosine kinase growth factor receptors activate mitogen-activated protein kinases which then translocate into the nucleus and phosphorylate nuclear targets. Alternative splicing results in multiple transcript variants. [provided by RefSeq, May 2014]

The c.846C>A (p.N282K) alteration is located in exon 4 (coding exon 3) of the MAPK4 gene. This alteration results from a C to A substitution at nucleotide position 846, causing the asparagine (N) at amino acid position 282 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
