In brief: Several

There are several genetic defects that lead to sickle cell anemia.
They all lead to a change in the 6th Amino Acid in the beta-globin chain in which valine is substituted for glutamic acid. At least 5 different dna mutations have been identified that all lead to the same Amino Acid substitution, and thus, sickle cell anemia.
