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]

Likely benign, criteria provided, single submitter	clinical testing	Women's Health and Genetics/Laboratory Corporation of America, LabCorp	Sep 26, 2021	Variant summary: MAP2K2 c.853G>A (p.Asp285Asn) results in a conservative amino acid change located in the Protein kinase domain (IPR000179) of the encoded protein sequence. Four of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 9.1e-05 in 231844 control chromosomes. The observed variant frequency is approximately 121 fold of the estimated maximal expected allele frequency for a pathogenic variant in MAP2K2 causing Cardiofaciocutaneous Syndrome phenotype (7.5e-07), strongly suggesting that the variant is benign. c.853G>A has been reported in the literature as a VUS in settings of multigene panel testing for individuals affected with cardiomyopathy (example, Aljeaid_2019). These report(s) do not provide unequivocal conclusions about association of the variant with Cardiofaciocutaneous Syndrome. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Four clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. Multiple laboratories reported the variant with conflicting assessments (likely benign, n=2; VUS, n=2). Based on the evidence outlined above, the variant was classified as likely benign. -
