NCIt definition : Human MAP3K1 wild-type allele is located in the vicinity of 5q11.2 and is approximately
82 kb in length. This allele, which encodes mitogen-activated protein kinase kinase
kinase 1 protein, plays a role in the protein kinase signal transduction cascade.;
NCIt note : A SNP has been identified in the MAP3K1 gene (rs889312), which is associated with
increases in breast cancer incidence. (Nature 2007; 447:1087-1093);
