Genes affected

MAPK3 (HGNC:6877): (mitogen-activated protein kinase 3) The protein encoded by this gene is a member of the MAP kinase family. MAP kinases, also known as extracellular signal-regulated kinases (ERKs), act in a signaling cascade that regulates various cellular processes such as proliferation, differentiation, and cell cycle progression in response to a variety of extracellular signals. This kinase is activated by upstream kinases, resulting in its translocation to the nucleus where it phosphorylates nuclear targets. Alternatively spliced transcript variants encoding different protein isoforms have been described. [provided by RefSeq, Jul 2008]

The c.1108C>T (p.R370C) alteration is located in exon 8 (coding exon 8) of the MAPK3 gene. This alteration results from a C to T substitution at nucleotide position 1108, causing the arginine (R) at amino acid position 370 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
