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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 31, 2023The c.388A>G (p.M130V) alteration is located in exon 2 (coding exon 1) of the MAPK4 gene. This alteration results from a A to G substitution at nucleotide position 388, causing the methionine (M) at amino acid position 130 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
