During The Venture of Prenatal Diagnosis of Thalassemia, a vis-à-vis Elucidated Collage of Genetic Polymorphism of West Bengal, India.

Introduction: Molecular screening of Thalassemia is a burning issue especially for developing country where birth rate is high and most of the victims are from rural and from economically downtrodden part of the society. Methods: The present study reports about the molecular diagnosis and pattern identification of Thalassemia carrier parents and females, who are in certain condition to determine their genotype of Chorionic Villi sample (CVS) to combat birth of new thalassemia baby. Result: Data suggest for the year 2014 and 15 that IVS 1-5(G-C) genotype heterozygous is the most prevalent for each year and affected CVS are either IVS 1-5(G-C) homozygous or compound heterozygous cases containing IVS 1-5(G-C). Bihar, Hooghly, Kolkata, North 24 Parganas, South Dinajpur and North Dinajpur is showing significant difference. Few regions are with a little laxity of patient flow for prenatal diagnosis. Conclusion: This data is useful to make a genetic micro map of West Bengal and also gives the vivid distribution of different Thalassemia gene across the state.
