Hemoglobinopathies and thalassemias are some of the most common single gene disorders in humans. These conditions are more common in certain ethnic groups, such as Asian, Mediterranean, African, Middle Eastern, Caribbean and South/Central American.
Approximately 5.2.% of the world’s population carries a significant hemoglobin variant1
At least 20% of the world’s population carries an alpha+ thalassemia variant1
Approximately 1 in 4 Ontarians identify as one of these ethnic groups2 and therefore may be at risk of having a child with a clinically significant blood disorder
