Genes affected

MAP3K7 (HGNC:6859): (mitogen-activated protein kinase kinase kinase 7) The protein encoded by this gene is a member of the serine/threonine protein kinase family. This kinase mediates the signaling transduction induced by TGF beta and morphogenetic protein (BMP), and controls a variety of cell functions including transcription regulation and apoptosis. In response to IL-1, this protein forms a kinase complex including TRAF6, MAP3K7P1/TAB1 and MAP3K7P2/TAB2; this complex is required for the activation of nuclear factor kappa B. This kinase can also activate MAPK8/JNK, MAP2K4/MKK4, and thus plays a role in the cell response to environmental stresses. Four alternatively spliced transcript variants encoding distinct isoforms have been reported. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Pathogenic. Variant got 13 ACMG points.

• PM1: In a region_of_interest Interaction with MAPK8IP1 (size 299) in uniprot entity M3K7_HUMAN there are 8 pathogenic changes around while only 0 benign (100%) in NM_145331.3
• PM2: Very rare variant in population databases, with high coverage
• PM4: Nonframeshift variant in NON repetitive region in NM_145331.3. Strenght limited to Supporting due to length of the change: 1aa.
• PP5: Variant 6-90571777-AAAC-A is Pathogenic according to our data. Variant chr6-90571777-AAAC-A is described in ClinVar as [Pathogenic]. Clinvar id is 264704.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

This variant has been reported to affect MAP3K7 protein function (PMID: 27426734). For these reasons, this variant has been classified as Pathogenic. This variant has been observed in individual(s) with cardiospondylocarpofacial syndrome (PMID: 27426734). It has also been observed to segregate with disease in related individuals. In at least one individual the variant was observed to be de novo. ClinVar contains an entry for this variant (Variation ID: 264704). This variant is not present in population databases (ExAC no frequency). This variant, c.148_150del, results in the deletion of 1 amino acid(s) of the MAP3K7 protein (p.Val50del), but otherwise preserves the integrity of the reading frame. -
