Genes affected

MAP2K1 (HGNC:6840): (mitogen-activated protein kinase kinase 1) The protein encoded by this gene is a member of the dual specificity protein kinase family, which acts as a mitogen-activated protein (MAP) kinase kinase. MAP kinases, also known as extracellular signal-regulated kinases (ERKs), act as an integration point for multiple biochemical signals. This protein kinase lies upstream of MAP kinases and stimulates the enzymatic activity of MAP kinases upon wide variety of extra- and intracellular signals. As an essential component of MAP kinase signal transduction pathway, this kinase is involved in many cellular processes such as proliferation, differentiation, transcription regulation and development.

MAP2K1 (HGNC:):

ACMG classification

Verdict is Uncertain_significance. Variant got 5 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in gene, where missense usually causes diseases (based on misZ statistic), MAP2K1. . Gene score misZ 3.1085 (greater than the threshold 3.09). Trascript score misZ 3.7499 (greater than threshold 3.09). GenCC has associacion of gene with Noonan syndrome with multiple lentigines, cardiofaciocutaneous syndrome 1, Noonan syndrome, cardiofaciocutaneous syndrome, cardiofaciocutaneous syndrome 3, Costello syndrome.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.867
