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 inherit one copy of most genes from their mother and one copy from their father. Both copies are typically active, or "turned on," in cells. However, the activity of the CDKN1C gene depends on which parent it was inherited from. In most tissues, the copy of the gene inherited from a person's mother (the maternally inherited copy) has much higher activity than the copy inherited from the father (the paternally inherited copy). This sort of parent-specific difference in gene activation is caused by a phenomenon called genomic imprinting.
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 (IC2) or KvDMR controls the parent-specific genomic imprinting of CDKN1C and several other genes thought to help regulate growth. The IC2 region undergoes a process called methylation, which is a chemical reaction that attaches small molecules called methyl groups to certain segments of DNA. Methylation, which occurs during the formation of an egg or sperm cell, is a way of marking or "stamping" the parent of origin. The IC2 region is normally methylated only on the maternally inherited copy of chromosome 11.
