NCIt definition : Human CCNE1 wild-type allele is located within 19q12 and is approximately 12 kb in
length. This allele, which encodes G1/S-specific cyclin-E1 protein, is involved in
the regulation of the G1/S transition of the cell cycle. Variant allelic overexpression
has been observed in many tumors, which results in chromosome instability, and thus
may contribute to tumorigenesis.;
