Sickle cell disease associated with thalassemia; description of a rare mutation.

Sickle cell disease (SCD) is a common hemoglobinopathy, secondary to alterations in the β globin chain, resulting in an abnormal hemoglobin variant named as hemoglobin S. These disorders show a wide phenotypical spectrum, and the prevalence of these disorders has significantly changed over the time because of multiple factors such as migration. We report a case of a 17-year-old black male, born in Gambia, diagnosed with sickle cell disease, who presented an associated mutation only described in a Japanese family [2].
