hemoglobinopathies/thalassemiasp1

Which of these is not a qualitative Disorder of hemobloniopathies?

• Result of inherited genetic mutations in which amino acid substitutions or deletions cause structural changes in globin chains of the Hgb molecule

• Altered amino acid sequence causes globin chains to behave differently—structurally, electrochemically, and functionally

• Causes an imbalance between “partner” chains

• Structurally abnormal Hgb may cause a wide range of clinical features, from none at all to life-threatening symptoms.

Which of these is NOT a Quantitative disorder of Thalassemias?

• Named according to decreased chain

  Alpha Thalassemia

  Beta Thalassemia

• Causes an imbalance between “partner” chains

• Result of various genetic defects that cause decreased synthesis of normal globin chains

• Altered amino acid sequence causes globin chains to behave differently—structurally, electrochemically, and functionally
