Sickle cell disease is one of the most common diseases
caused by a mutation in a single gene (Rees, Williams,
and Gladwin 2010). In the United States, approximately
70,000 people have the disease and an additional 2.5
million have sickle cell traits (Gallo et al. 2010). The disease
is a blood disorder that is common among people
with ancestors from sub-Saharan Africa; red blood cells
break down and cause symptoms such as anemia and
obstructed blood vessels that lead to severe pain and
organ damage (Creary, Williamson, and Kulkarni 2007).
