Background: The inherited hematological condition thalassemia is defined by a reduction in or lack of synthesis of one or more globin chains. One or more mutations in the beta-globin gene cause β thalassemia. Because of dyslipidemia, children with beta thalassemia are susceptible to early atherosclerosis. Some clinical characteristics of thalassemia, such as altered endocrine function and greater susceptibility to infections and vascular problems, may be pathologized by lipids and lipoproteins. The objective is to assess the serum lipid profiles of individuals with β thalassemia and determine any potential genetic correlations. Subjects and methods:The study included 73 children with β thalassemia and 73 age and sex matched children as a control group. Lipid profile was assessed in both groups. Patients genotype was analyzed by PCR. Results: In β thalassemia patients, total cholesterol, LDL-C, and HDL-C levels were significantly decreased while, TG concentration was significantly increased in patients compared to normal control group.  49.3% of patients had β⁺β⁺ genotype, 35.6% of them had β⁰β⁰ genotype and 15.1% had β⁰β⁺. The commonest mutation was the homozygous IVS 1–1 (19.2%) followed by homozygous IVS 1-110 (15.1%) then homozygous IVS 1-6 (11%). β⁰β⁰ genotype is correlated with more reduction in TC, and LDL-C HDL-C levels and more increase in TG level. Conclusion: We recommend regular monitoring of lipid profile in patients with β thalassemia, especially those with β⁰β⁰ genotype to prevent or at least enhance the early detection of cardiac disease.
