What is the official name of the CDKN1C gene?
The official name of this gene is “cyclin-dependent kinase inhibitor 1C (p57, Kip2).”
CDKN1C is the gene's official symbol. The CDKN1C gene is also known by other names, listed below.

What is the normal function of the CDKN1C gene?
The CDKN1C gene provides instructions for making a protein that helps regulate growth. This protein acts as a tumor suppressor, which means that it keeps cells from growing and dividing too fast or in an uncontrolled way. It also is involved in controlling growth before birth, preventing the developing fetus from becoming too large.
People generally inherit one copy of a gene from their mother and one copy from their father. For most genes, both copies are fully turned on (active) in cells. The CDKN1C gene, however, is most active when it is inherited from a person's mother. The copy of CDKN1C inherited from a person's father is active at much lower levels in most tissues. This sort of parent-specific difference in gene activation is caused by a phenomenon called genomic imprinting. When genomic imprinting reduces the activity of the copy of a gene inherited from the father, that gene is said to be paternally imprinted.
CDKN1C is part of a cluster of genes on the short (p) arm of chromosome 11 that undergo genomic imprinting. A nearby region of DNA known as imprinting center 2 (ICR2) or KvDMR controls the parent-specific genomic imprinting of CDKN1C and several other genes thought to help regulate growth.
