Genes affected

MAP3K8 (HGNC:6860): (mitogen-activated protein kinase kinase kinase 8) This gene is an oncogene that encodes a member of the serine/threonine protein kinase family. The encoded protein localizes to the cytoplasm and can activate both the MAP kinase and JNK kinase pathways. This protein was shown to activate IkappaB kinases, and thus induce the nuclear production of NF-kappaB. This protein was also found to promote the production of TNF-alpha and IL-2 during T lymphocyte activation. This gene may also utilize a downstream in-frame translation start codon, and thus produce an isoform containing a shorter N-terminus. The shorter isoform has been shown to display weaker transforming activity. Alternate splicing results in multiple transcript variants that encode the same protein. [provided by RefSeq, Sep 2011]

The c.200G>A (p.G67D) alteration is located in exon 3 (coding exon 1) of the MAP3K8 gene. This alteration results from a G to A substitution at nucleotide position 200, causing the glycine (G) at amino acid position 67 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

This sequence change replaces glycine, which is neutral and non-polar, with aspartic acid, which is acidic and polar, at codon 67 of the MAP3K8 protein (p.Gly67Asp). This variant is present in population databases (rs767198025, gnomAD 0.04%). This variant has not been reported in the literature in individuals affected with MAP3K8-related conditions. An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant¬†is likely to be tolerated. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
