I think that this condition is :Sickle Cell Anaemia BECAUSE HB.very low=6.5 ;MCV normal and it contain NRBC and Sickle cell.
This type of anaemia is normocytic normochromic and has Missense mutation.
وعلى أساس هذا التفسير كانت الاجابة.
sickle cell aneamia is duo to substituation of amino acids
السلام عليكم يا دكتور محمد:
It is correct that sickle cell anemia is due an amino acid substituation, but originally the defect is a missense mutation at the DNA level.
41- Which is a correct statement about F cells:
A- They are fetal red cells and they synthesize HbA.
B- They are adult red cells that are still able to synthesize HbF.
C- They are abnormal red cells present in fetus.

42- A 12-year-old girl has a sudden onset of severe abdominal pain. On physical examination her abdomen is tender. She has no fever. A CBC shows Hb 6.5 g/dL, Hct 19.0%, MCV 99 fl, PLT count 149 x109/L, and WBC count 11.2 x109/L. Examination of her blood film shows NRBCs and sickled RBCs. Which of the following gene mutations is she most likely to have?
A- Sense mutation.
B- Nonsense mutation.
C- Missense mutation.
D- Deletion
E- Splicing
