Variant summary

Our verdict is Benign. The variant received -7 ACMG points: 1P and 8B. PP3BS1BS2

The NM_030662.4(MAP2K2):c.806C>T(p.Pro269Leu) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000479 in 1,607,542 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P269R) has been classified as Uncertain significance. The gene MAP2K2 is included in the ClinGen Criteria Specification Registry.

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]

ACMG classification

Specifications for MAP2K2 are available in the ClinGen Criteria Specification Registry and recommended for reference when assigning criteria.

Classification was made for transcript

Our verdict: Benign. The variant received -7 ACMG points.

PP3

MetaRNN computational evidence supports a deleterious effect, 0.817

BS1

Variant frequency is greater than expected in population eas. GnomAdExome4 allele frequency = 0.0000515 (75/1455320) while in subpopulation EAS AF = 0.00122 (48/39418). AF 95% confidence interval is 0.000944. There are 0 homozygotes in GnomAdExome4. There are 41 alleles in the male GnomAdExome4 subpopulation. Median coverage is 33. This position passed quality control check.

BS2

High AC in GnomAdExome4 at 75 AD gene.
