Identification of three new nucleotide substitutions in the β‐globin gene: laboratoristic approach and impact on genetic counselling for beta‐thalassaemia

Over the past two decades, a wide range of available methods for DNA analysis have allowed us to identify defects in globin genes associated with haemoglobin disorders and to correlate specific mutations with phenotypic expression. The purpose of this study was to evaluate the nature of three new nucleotide changes, mutation or single nucleotide polymorphism, found in the beta‐globin gene, to conduct an appropriate genetic counselling.
