Variant summary

Our verdict is Benign. The variant received -9 ACMG points: 0P and 9B. BA1BP5

This summary comes from the ClinGen Evidence Repository: The filtering allele frequency of the c.848C>T (p.Ala283Val) variant in the MAP2K1 gene is 0.052% for African chromosomes by the Exome Aggregation Consortium (10/10366 with 95% CI), which is a high enough frequency to be classified as benign based on thresholds defined by the ClinGen RASopathy Expert panel for autosomal dominant RASopathy variants (BA1). This variant has been identified in a patient with an alternate molecular basis for disease (BP5; Partners LMM, GeneDx internal data; GTR ID: 21766, 26957; ClinVar SCV000207935.12; SCV000061262.5). In summary, this variant meets criteria to be classified as benign. RASopathy-specific ACMG/AMP criteria applied (PMID:29493581): BA1, BP5.

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.
