sickle cell disease and sickle cell trait: variation ..
Sickle Cell Disease (SCD) is the most common serious genetic disease in Africa. Ghana and other countries in West and Central Africa have the highest prevalence of SCD and related disorders in the world. In Ghana about 2% of newborns have sickle cell disease which translates to about 16,000 to 18,000 children born annually with SCD, with 20% – 25 % born as trait or carriers.
Sickle-cell trait is often referred to as sickle-cell anemia.
Some simple examples of this immigration and residence information are inorder. Towns such as Palermo, Castrogiovanni (Enna), Calascibetta, Caltanissetta,Caltagirone, Caltabellotta,Racalmuto, Favara, Mistretta, Marsala, Mussomeli and Misilmeri were eitherfounded by Arabs or grew considerably under Arab domination, and bore Arabicnames (under the Greeks Palermo, from the Arabic Bal'harm, was Panormos). Thespecific mention of Arabs and the presence of Arabic given names and surnames wasevident in these places long after Frederick II banished a few thousand Arabs ofwestern Sicily to Apulia. As regards Jews present in many Sicilian localitiesuntil 1492, those who converted usually continued to name their childrenaccording to tradition (hence Abramo, Beniamino, Isacco, etc.) and to practiceprofessions traditionally associated with Jews in Sicily (dyers, bankers). Manyassumed distinctive surnames (Siino for Zion, Rabino for Rabbi) indicating aJewish orgin. Similar generalities about the permanence of Phoenician,Carthaginian, Greek and Roman populations in Sicily are valid. Where are thesepeoples today? Genetically (so to speak), they are represented in the modernSicilians --an amalgamated group of European and Mediterranean peoples. However,as we shall see, genetics and ethnic identity are two distinct ideas.
