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.487G>C (p.V163L) alteration is located in exon 2 (coding exon 1) of the MAPK4 gene. This alteration results from a G to C substitution at nucleotide position 487, causing the valine (V) at amino acid position 163 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
