WebMore than 1000 hemoglobin mutations are known, and occasionally they can affect the stability and function of hemoglobin and cause hemolytic anemia ( Chapter 161 ), disordered oxygen transport ( Chapter 169 ), or methemoglobinemia ( Chapter 161 ). However, most globin mutations are clinically insignificant.
