Genetic assessment of serological and biochemical markers in Bharia tribe of Chhindwara district of Madhya Pradesh

Abstract

BACKGROUND:The present sero-genetic study is the first of its kind to present the baseline data of Bharia tribe of Madhya Pradesh. The main aim of this study is to provide phenotype and allele-frequency data to characterize the population genetically and to fill the void on the genetic map of Madhya Pradesh.MATERIALS AND METHODS:For this, blood samples from 92 unrelated healthy individuals of Bharia tribe from Chhindwara district (Tamia block) were collected. Hemolysates prepared were analyzed for two serological (A1A2BO and Rh) and six biochemical (adenosine deaminase, adenylate kinase locus 1, acid phosphatase locus 1, phosphoglucomutase locus 1, esterase D and glucosephosphate isomerase) parameters, following the standard electrophoretic techniques.RESULTS:The Chi-square test for goodness of fit revealed no significant deviation between the observed and expected numbers in any of the seven genetic markers, suggesting that the tribe is in genetic equilibrium. A high incidence of B allele in A1A2BO blood group and low incidence of the A1 allele, with presence of A2 in only one individual, and a low frequency of Rh(D) (Rh negative allele) was observed in serological markers. Also, no rare variant was observed for biochemical markers.CONCLUSION:Principal Component Analysis done in order to detect the genetic affinity of Bharia tribe with other populations from the adjoining states of Madhya Pradesh based on the allele frequencies, showed a close association of Bharia with Gujarat and Rajasthan. Hence, this study has been helpful in revealing the genetic structure and affinity of Bharia tribe.

“…Numerous studies were reported at the context of disease epidemiology and genetics, upon various indian tribal communities, who are highly isolated both demographically and topogra phically, from the mainstream indian populations [4][5][6][7][8][9][10][11][12][13][14][15][16].…”
