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]

Ambry Genetics

Aug 02, 2021

The c.1020G>A (p.M340I) alteration is located in exon 5 (coding exon 4) of the MAPK4 gene. This alteration results from a G to A substitution at nucleotide position 1020, causing the methionine (M) at amino acid position 340 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
