Variant summary

Our verdict is Benign. The variant received -8 ACMG points: 0P and 8B. BA1

This summary comes from the ClinGen Evidence Repository: The filtering allele frequency of the c.823C>T (p.Leu275=) variant in the MAP2K2 gene is 0.2% (19/6224) of African chromosomes by the Exome Aggregation Consortium, which is a high enough frequency to be classified as benign based on thresholds defined by the ClinGen RASopathy Expert Panel (BA1; PMID:29493581) LINK:https://erepo.genome.network/evrepo/ui/classification/CA137969/MONDO:0021060/004

Genes affected
MAP2K2 (HGNC:6842): (mitogen-activated protein kinase kinase 2) The protein encoded by this gene is a dual specificity protein kinase that belongs to the MAP kinase kinase family. This kinase is known to play a critical role in mitogen growth factor signal transduction. It phosphorylates and thus activates MAPK1/ERK2 and MAPK2/ERK3. The activation of this kinase itself is dependent on the Ser/Thr phosphorylation by MAP kinase kinase kinases. Mutations in this gene cause cardiofaciocutaneous syndrome (CFC syndrome), a disease characterized by heart defects, cognitive disability, and distinctive facial features similar to those found in Noonan syndrome. The inhibition or degradation of this kinase is also found to be involved in the pathogenesis of Yersinia and anthrax. A pseudogene, which is located on chromosome 7, has been identified for this gene. [provided by RefSeq, Jul 2008]
