Abstract
A case of β-thalassemia minor with thalassemia gene on the mother's side was reported.
The propositus, a four-month-old boy, with hepatosplenomegaly had a hypochromic microcytic anemia and in the periperal blood smear anisocytosis, poikilocytosis and basophilic stippling were observed.
Osmotic fragility was markedly decreased. Target cells were seen in mother's periperal blood smear.
On starch block electrophoresis the amount of Hb A2 comprised 3.1 per cent of the total hemoglobin at the age of eight months.
His mother, maternal grandfather and aunt had A2 hemoglobin fractions of 4.3-5.4 per cent.
