Variant summary

Our verdict is Likely pathogenic. Variant got 7 ACMG points: 7P and 0B. PM2 PM5 PP3 PP5_Moderate

The NM_005921.2(MAP3K1):​c.566T>C​(p.Leu189Pro) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Pathogenic (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. L189Q) has been classified as Likely pathogenic.

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_pathogenic. Variant got 7 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PM5: Other missense variant is known to change same aminoacid residue: Variant chr5-56856683-T-A is described in Lovd as [Likely_pathogenic].
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.794
• PP5: Variant 5-56856683-T-C is Pathogenic according to our data. Variant chr5-56856683-T-C is described in ClinVar as [Pathogenic]. Clinvar id is 30146.Status of the report is criteria_provided_single_submitter, 1 stars. Variant chr5-56856683-T-C is described in Lovd as [Likely_pathogenic].

The MAP3K1 c.566T>C variant is predicted to result in the amino acid substitution p.Leu189Pro. This variant has been previously reported in an individual with 46,XY complete gonadal dysgenesis (Pearlman et al. 2010. PubMed ID: 21129722). Functional studies support its pathogenicity (Loke and Ostrer. 2012. PubMed ID: 22171599; Upadhyay et al. 2018. PubMed ID: 29095481; Chamberlin et al. 2019. PubMed ID: 30608580). Alternative nucleotide changes affecting the same amino acid (p.Leu189Arg and p.Leu189Gln) have also been reported in unrelated individuals with disorders of sex development (Pearlman et al. 2010. PubMed ID: 21129722; Granados et al. 2017. PubMed ID: 28504475). The c.566T>C (p.Leu189Pro) variant has not been reported in a large population database (http://gnomad.broadinstitute.org), indicating this variant is rare. In summary, this variant is interpreted as pathogenic. -
