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.169G>A (p.D57N) 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 169, causing the aspartic acid (D) at amino acid position 57 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

This sequence change replaces aspartic acid, which is acidic and polar, with asparagine, which is neutral and polar, at codon 57 of the MAP3K8 protein (p.Asp57Asn). This variant is present in population databases (rs150001848, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with MAP3K8-related conditions. ClinVar contains an entry for this variant (Variation ID: 1371248). 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. -

The MAP3K8 c.169G>A variant is predicted to result in the amino acid substitution p.Asp57Asn. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.033% of alleles in individuals of East Asian descent in gnomAD. Although we suspect that this variant may be benign, at this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
