Sickle Cell and Thalassaemia

Sickle Cell and Thalassaemia are inherited blood disorders, which mainly affects people whose origins are from Africa , Asia , the Middle East , the Mediterranean and the Caribbean .

There are two forms, the carrier states known as traits and the serious disorders - sickle cell anaemia and Thalassaemia major.

People who are carriers have inherited Sickle Cell or Thalassaemia from only one parent. They will not have any ill health and they will not develop a major illness.

People who inherited Sickle Cell or Thalassaemia from both parents have serious illness which requires lifelong treatment, but for which there is as yet no cure.

Individuals who are born with sickle cell anaemia have episodes of intense pain, severe anaemia and damage to their joints.

Those who are born with Thalassaemia major, have a very severe anaemia. They must have frequent blood transfusions throughout their lives.

Sickle Cell and Thalassaemia trait are important because they can be passed on to children. If a couple who are carriers have children there is a 25% chance with every pregnancy of having a baby with sickle cell anaemia or Thalassaemia major.

A simple blood test can detect Sickle Cell or Thalassaemia trait.

The Sickle Cell & Thalassaemia Unit provides:
  • Genetic Screening & Counselling for expectant carrier couples
  • Genetic Counselling for people who have been found to be carriers
  • Screening and counselling for the families of carriers
