Genes affected

MAP2K5 (HGNC:6845): (mitogen-activated protein kinase kinase 5) The protein encoded by this gene is a dual specificity protein kinase that belongs to the MAP kinase kinase family. This kinase specifically interacts with and activates MAPK7/ERK5. This kinase itself can be phosphorylated and activated by MAP3K3/MEKK3, as well as by atypical protein kinase C isoforms (aPKCs). The signal cascade mediated by this kinase is involved in growth factor stimulated cell proliferation and muscle cell differentiation. Three alternatively spliced transcript variants of this gene encoding distinct isoforms have been described. [provided by RefSeq, May 2011]

MAP2K5 (HGNC:):

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.51).
• BS1: Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.0238 (3625/152330) while in subpopulation NFE AF= 0.0401 (2725/68022). AF 95% confidence interval is 0.0388. There are 58 homozygotes in gnomad4. There are 1651 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck.
• BS2: High AC in GnomAd4 at 3625 AD gene.
