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.

Benign, criteria provided, single submitter	clinical testing	Women's Health and Genetics/Laboratory Corporation of America, LabCorp	Sep 05, 2016	Variant summary: The MAP2K1 c.804C>G (p.Ala268Ala) variant involves the alteration of a non-conserved nucleotide, resulting in a synonymous change. 5/5 splice prediction tools predict this variant not to significantly affect normal splicing. This variant was found in 230/121392 control chromosomes (6 homozygotes), predominantly observed in the South Asian subpopulation at a frequency of 0.0138081 (228/16512). This frequency is about 5523 times the estimated maximal expected allele frequency of a pathogenic MAP2K1 variant (0.0000025), suggesting this is a benign polymorphism found primarily in the populations of South Asian origin. In addition, one clinical diagnostic laboratory in ClinVar has classified this variant as benign. The variant of interest has not, to our knowledge, been reported in affected individuals via publications and/or reputable databases. One internal sample carrying this variant also carries a known pathogenic variant PTPN11 p.Y63C. Taken together, this variant is classified as Benign. -
