Genes affected

MAP4K2 (HGNC:6864): (mitogen-activated protein kinase kinase kinase kinase 2) The protein encoded by this gene is a member of the serine/threonine protein kinase family. Although this kinase is found in many tissues, its expression in lymphoid follicles is restricted to the cells of germinal centre, where it may participate in B-cell differentiation. This kinase can be activated by TNF-alpha, and has been shown to specifically activate MAP kinases. This kinase is also found to interact with TNF receptor-associated factor 2 (TRAF2), which is involved in the activation of MAP3K1/MEKK1. Alternative splicing results in multiple transcript variants.

MAP4K2 (HGNC:):

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.89).
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00865 (1305/150954) while in subpopulation AFR AF= 0.029 (1171/40418). AF 95% confidence interval is 0.0276. There are 18 homozygotes in gnomad4. There are 602 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 18 AR gene
