Distribution of ABO and Rh(D) Blood Group System among Dangi Community of Udaipur, Rajasthan

Abstract

Blood is the most important body fluid, which is responsible for circulation of important nutrients, enzymes, and hormones all across the body. Frequency distribution of blood groups is important as it is used in modern medicine, genetic research, anthropology, and tracing ancestral relations of humans. The present study deals with the distribution of ABO and Rh(D) blood group system among Dangi community of Udaipur, Rajasthan which is least explored community particularly on genetic trait studies. A total of 130 unrelated individuals (male=85, female=45) age ranges from 8 to 19 years (mean age=14.47) were screened for ABO and Rh(D) blood group system. Bloods were collected by finger prick method using sterile lancet with prior informed oral consent from the subjects. The phenotypic frequency of blood group ‘B’ (38.46%) was the most common followed by group ‘O’ (33.85%), ‘A’ (22.31%) and ‘AB’ (5.38%) following the trend of B>O>A>AB. The phenotypic frequency of Rh(D) (93.85%) is higher than Rh(d) (6.15%) of the studied community. Interestingly, the present study revealed high prevalence of Rh(d) (6.15%) among the Dangi, however males shows greater prevalence of Rh negative with 8.24% as compared to females (2.22%).
