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.

ACMG classification
Classification made for transcript
Verdict is Pathogenic. Variant got 13 ACMG points.
PM1
?
In a hotspot region, there are 6 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 3 uncertain in NM_002755.4
PM2
?
Very rare variant in population databases, with high coverage;
PM4
?
Nonframeshift variant in NON repetitive region in NM_002755.4. Strenght limited to Supporting due to length of the change: 1aa.
PP5
?
Variant 15-66435118-CAGA-C is Pathogenic according to our data. Variant chr15-66435118-CAGA-C is described in ClinVar as [Likely_pathogenic]. Clinvar id is 222074.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

Likely pathogenic, criteria provided, single submitter | clinical testing | Invitae | Sep 02, 2022 | In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. Experimental studies have shown that this variant affects MAP2K1 function (PMID: 29753091). Algorithms developed to predict the effect of variants on protein structure and function are not available or were not evaluated for this variant. ClinVar contains an entry for this variant (Variation ID: 222074). This variant has been observed in individual(s) with cardio-facio-cutaneous syndrome (PMID: 17551924). In at least one individual the variant was observed to be de novo. This variant is not present in population databases (gnomAD no frequency). This variant, c.175_177del, results in the deletion of 1 amino acid(s) of the MAP2K1 protein (p.Lys59del), but otherwise preserves the integrity of the reading frame. - |
