#مــــــــــــــــــعـــــــــــــــــلــــــــــــــــــومــــــــــــــــــه **□the clinical manifestations of α-thalassaemia depend upon the number of genes deleted.  So 

α-thalassaemias are classified into 4 types:

1. Four α-gene deletion:
   Hb Bart’s hydrops foetalis.

🌺Hb Bart’s is
a gamma globin chain tetramer (γ4) which has
high oxygen affinity leading to severe tissue hypoxia.🤕

لذلك الطفل يولد ميتاً داخل الرحم أو بعد الولادة مباشرة وإذا عاش الأعراض بتكون مشابهة ل
{Severe Rh haemolytic disease are present}

1. Three α-gene deletion: HbH disease.

2. Two α-gene deletion:
   α-thalassaemia trait.

3. One α-gene deletion: α-thalassaemia trait (carrier).**
