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]

Sep 13, 2023

The c.121C>T (p.R41W) alteration is located in exon 2 (coding exon 1) of the MAPK4 gene. This alteration results from a C to T substitution at nucleotide position 121, causing the arginine (R) at amino acid position 41 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
