The CTNND2 gene provides instructions for making a protein called delta-catenin. This protein is active in the nervous system, where it likely helps cells stick together (cell adhesion) and plays a role in cell movement. In the developing brain, it may help guide nerve cells to their proper positions as part of a process known as neuronal migration.
Normal function
The CTNND2 gene provides instructions for making a protein called delta-catenin. This protein is active in the nervous system, where it likely helps cells stick together (cell adhesion) and plays a role in cell movement. In the developing brain, it may help guide nerve cells to their proper positions as part of a process known as neuronal migration.
In mature nerve cells, delta-catenin is located in specialized outgrowths called dendrites. Dendrites branch out from the cell and receive information from nearby nerve cells. This information is relayed across synapses, which are junctions between nerve cells where cell-to-cell communication occurs. Delta-catenin appears to play a crucial role in the function of synapses.

Thalassaemia
Haemoglobin is made out of different parts. The main parts are called alpha chains and beta chains which are put together to make the haemoglobin molecule. In thalassaemia, part of the haemoglobin is faulty - usually either the alpha chains or the beta chains. This means that some of the haemoglobin does not work properly. As a result, there is.
