Variant summary

Our verdict is Uncertain significance. Variant got 2 ACMG points: 2P and 0B. PM2

The NM_001042600.3(MAP4K1):c.431_432insT(p.Ile145HisfsTer3) variant causes a frameshift change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Variant results in nonsense mediated mRNA decay.

• Frequency: Genomes: not found (cov: 31)
• Consequence: MAP4K1 NM_001042600.3 frameshift
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 8.33

Genes affected

MAP4K1 (HGNC:6863): (mitogen-activated protein kinase kinase kinase kinase 1) Enables ATP binding activity and MAP kinase kinase kinase kinase activity. Involved in several processes, including JNK cascade; cellular response to phorbol 13-acetate 12-myristate; and protein phosphorylation. Located in membrane.
