The TCOF1 gene provides instructions for making a protein called treacle. This protein is active during early embryonic development in structures that become bones and other tissues of the face, and it appears to play a critical role in the formation of these structures.
Normal function
The TCOF1 gene provides instructions for making a protein called treacle. This protein is active during early embryonic development in structures that become bones and other tissues of the face, and it appears to play a critical role in the formation of these structures.
Studies suggest that treacle is involved in the production of a molecule called ribosomal RNA (rRNA), a chemical cousin of DNA. Ribosomal RNA helps assemble protein building blocks (amino acids) into functioning proteins, which is essential for the normal functioning and survival of cells. Treacle is active in the nucleolus, which is a small region inside the nucleus where rRNA is produced.

Breast cancer facts and risk factors
Most cases of breast cancer occur by chance. However, breast cancer does occur more often than usual in some families because of their genetic makeup. Most cases of breast cancer occur by chance.

Causes of cancer
Certain risk factors are known to increase the chance that one or more of your cells will become abnormal and lead to cancer. How does cancer start. The body is made up from millions of tiny cells. Different parts of the body such as organs, bones, muscles, skin and blood are made up from different specialised cells. Most cells have a centre.
