Abstract
Sickle cell disease is one of the commonest severe monogenic disorders seen worldwide. Hemoglobin S (Hb S) is the result of a single base-pair change, thymine for adenine, at the sixth codon of the β globin gene. This change encodes valine instead of glutamine in the sixth position in the β globin molecule. In the United States, sickle cell disease occurs in African Americans at a rate of 1 : 396 births and in Hispanics at a rate of 1: 36,000 births.. In UK the prevalence is 1 : 2000 live births. In India SCD gene frequency varies from 2 to 14 % of at risk population and is as common as thalassemia; but less highlighted due to the predominantly underprivileged, tribal population of Central India (Vidharbha, Marathwada, M.P., AP, West-Odisha., Chhattisgarh & Gujrat).
