The RUNX1 gene provides instructions for making a protein called runt-related transcription factor 1 (RUNX1). Like other transcription factors, the RUNX1 protein attaches (binds) to specific regions of DNA and helps control the activity of particular genes. This protein interacts with another protein called core binding factor beta or CBFβ (produced from the CBFB gene), which helps RUNX1 bind to DNA and prevents it from being broken down. Together, these proteins form one version of a complex known as core binding factor (CBF). The RUNX1 protein turns on (activates) genes that help control the development of blood cells (hematopoiesis). In particular, it plays an important role in development of hematopoietic stem cells, early blood cells that have the potential to develop into all types of mature blood cells such as white blood cells, red blood cells, and platelets.

Dupuytren's contracture
This forms into... The abnormal tissue that forms is similar to scar tissue that forms following a wound. The reason why this tissue becomes thickened is not known. There seems to be a genetic factor as it has a tendency to run in families, so there may be a family history. It is more common in some countries - mainly Northern European. It is more.

This is done in a similar way to a lumbar puncture (described above) and is called an intrathecal injection. In some cases, radiotherapy to the brain is also used. Stem cell transplantation (SCT) SCT - sometimes called bone marrow transplantation - may be performed. It may be used for cases where the leukaemia has come back (recurred) following.

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. If your risk is moderate or high then, if you wish, you may ... For details of the factors used to assess the risk, see the website of the National Institute for Health and Care Excellence (NICE).

Alpha-1 antitrypsin deficiency
A... This can show which variation of the A1AT faulty gene a person has. It can therefore show how severely affected they are likely to be. Because A1AT deficiency runs in families, if a person is found to have A1AT deficiency, other family members should also be tested. Various other tests may be suggested to determine how severely a person is.
