NCIt definition : Human PREX2 wild-type allele is located in the vicinity of 8q13.2 and is approximately
285 kb in length. This allele, which encodes phosphatidylinositol 3,4,5-trisphosphate-dependent
Rac exchanger 2 protein, plays a role in the regulation of small GTPase-dependent
signaling.;
NCIt note : Mutation of the PREX2 gene is associated with melanoma. (Nature. 2012; doi:10.1038/nature11071.);
