Thalassaemia is part of a family of genetic conditions affecting the blood known as haemoglobin disorders.

Haemoglobin is a substance in the red blood cells that carries oxygen and a lack of it triggers anemia, leaving patients very weak, short of breath and pale.

The most severe type of the condition is typically inherited when both parents are carriers. Those patients often require regular blood transfusions - about 450 of the UAE's 2,000 thalassaemia patients - though frequent transfusions can lead to too much iron in the body and heart and liver problems.

The condition mainly affects people of Mediterranean, South Asian, South-East Asian and Middle Eastern origin. Saudi Arabia recorded 45,892 cases of carriers between 2004 and 2014.

A World Health Organisation study estimated that globally there are at least 950,000 'new carrier couples' every year and annually there are 1.33 million at-risk pregnancies.

• Canada and Mexico are significant energy suppliers to the US, providing the majority of oil and natural gas imports
• The introduction of tariffs could hinder the US's clean energy initiatives by raising input costs for materials like nickel
• US domestic suppliers might benefit from higher prices, but overall oil consumption is expected to decrease due to elevated costs
