Sickle Delta Beta Thalassemia - A Compound Heterozygous Sickle Cell Variant
Subscribe/Renew Journal
Sickle cell disease occurs when an individual is homozygous for sickle cell mutation (β6-Glutamic acid β Valine) (HbS/A: 100/0; HbF: 2 - 25%). Heterozygous mutation results in sickle cell trait (HbS/ HbA: 40/60).Inheritance of sickle cell gene along with mutations of α/β/δ genes in compound heterozygosis results in sickle cell variants. CASE REPORT: A 16year old male patient presented with fever, pain abdomen, anaemia, massive tender splenomegaly, unconjugated hyperbilirubinemia, microcytic hypochromic anaemia with sickle cells and target cells, elevatedHbF, HbS with normal HbA2 and decreased HbA.
