Web27 nov. 2016 · Sickle cell hemoglobin is of great clinical importance in many parts of the world. The disease results from a single nucleotide substitution that changes the codon of the sixth amino acid of β-globin from glutamic acid to valine (GAG → GTG: Glu6Val; see Table 11-3 ). Homozygosity for this mutation is the cause of sickle cell disease (Case 42). Web1 feb. 2001 · Hb Chesapeake was first discovered in 1966, as a rare but with very high-oxygen-affinity [35].
