Haemoglobinopathies and glucose-6-phosphate dehydrogenase deficiency in a Scandinavian perspective.
Haemoglobinopathies (mainly thalassaemia and sickle-cell anaemia syndromes) and glucose-6-phosphate dehydrogenase deficiency (G6PD) are globally among the most prevalent single-genomic diseases. About 3% of the world's population are heterozygotic for beta-thalassaemia and about 1-2% for sickle-cell anaemia, and it is estimated that more than 400 million people are affected by G6PD deficiency worldwide. The disorders are most prevalent in the Mediterranean area, in Asia and Africa. The Scandinavian countries, among others, have seen a boom in immigration during the past 20 years, and therefore migration makes haemoglobinopathies as well as G6PD deficiency increasingly more important from a differential diagnostic perspective in most countries. The purpose of the present special issue of the Journal is to summarize current epidemiological data and elucidate trends and practices in the laboratory diagnosis of these disorders.
