Genes affected

MAP3K1 (HGNC:6848): (mitogen-activated protein kinase kinase kinase 1) The protein encoded by this gene is a serine/threonine kinase and is part of some signal transduction cascades, including the ERK and JNK kinase pathways as well as the NF-kappa-B pathway. The encoded protein is activated by autophosphorylation and requires magnesium as a cofactor in phosphorylating other proteins. This protein has E3 ligase activity conferred by a plant homeodomain (PHD) in its N-terminus and phospho-kinase activity conferred by a kinase domain in its C-terminus.

ACMG classification

Verdict is Likely_benign. Variant got -2 ACMG points.

• PM4: Nonframeshift variant in NON repetitive region in NM_005921.2.
• BS2: High AC in GnomAdExome4 at 6 AD gene.

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. Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. This variant has not been reported in the literature in individuals affected with MAP3K1-related conditions. This variant is not present in population databases (gnomAD no frequency). This variant, c.11_16dup, results in the insertion of 2 amino acid(s) of the MAP3K1 protein (p.Ala4_Ala5dup), but otherwise preserves the integrity of the reading frame. -
