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]

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.8).
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.482 is higher than 0.05.
