Description

Variant summary: The MAP2K1 c.812T>G (p.Leu271Arg) variant located in the protein kinase domain (via InterPro) causes a missense change involving a conserved nucleotide, which 4/4 in silico tools (SNPs&GO not captured here due to low reliability index) predicts a "damaging" outcome, although these predictions have yet to be functionally assessed. The variant of interest was not observed in controls (ExAC, 1000 Gs, or ESP), nor has it been, to our knowledge, reported in affected individuals via publications and/or clinical diagnostic laboratories/databases. Therefore, until additional information becomes available (ie, clinical and functional studies), the variant has been classified as a "Variant of Uncertain Significance (VUS)."

Description

Not observed at significant frequency in large population cohorts (gnomAD); Missense variants in this gene are a common cause of disease and they are underrepresented in the general population; In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; Has not been previously published as pathogenic or benign to our knowledge; This variant is associated with the following publications: (PMID: 29493581)
