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.

This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 153 of the MAP3K1 protein (p.Pro153Leu). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individuals with gonadal dysplasia (PMID: 24135036; Invitae). ClinVar contains an entry for this variant (Variation ID: 435820). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt MAP3K1 protein function with a negative predictive value of 95%. Experimental studies have shown that this missense change affects MAP3K1 function (PMID: 24135036, 30608580). 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. -

Collection Method: clinical testing

The P153L variant in the MAP3K1 gene has been reported previously in an individual with abnormal gonadal development with no further clinical details provided (Loke et al., 2014). Functional studies of this variant demonstrated altered binding of protein co-factors and increased phosphorylation of downstream targets, suggesting a possible gain of function (Loke et al., 2014). However, the clinical validity of these functional studies is unknown (Bashamboo et al., 2015). The P153L variant is not observed in large population cohorts (Lek et al., 2016). The P153L variant is a semi-conservative amino acid substitution, which may impact secondary protein structure as these residues differ in some properties. However, in-silico analyses, including protein predictors and evolutionary conservation, support that this variant does not alter protein structure/function. We interpret P153L as a variant of uncertain significance. -
