“Prevalence of of ABO and Rhesus (Rh) Blood Groups in Eastern UP Population”

Abstract

Approximately 300 different types of blood groups are identified so far, the ABO and Rh antigens are still the clinically most significant and genetically most polymorphic of all human blood group systems to date. A total of 200 unrelated individuals from Uttar Pradesh were studied for the phenotype and allele frequency distribution of ABO and Rh (D) blood groups. In total 200 samples analyzed, phenotype B blood type has the highest frequency 36.5% (n=73), followed by O (34.5%; n=69), A (20.5%; n=41) and AB (8.5%; n=17). The O, A and B frequencies were 0.5849, 0.1571 and 0.2580 respectively. The overall phenotypic frequencies of ABO blood groups were B>O>A>AB. The variation in phenotypic frequencies between male and female might be due to small sample size of male sample. The allelic frequency of Rh-negative was 0.2.

“…Blood group B is most common blood group followed by blood group O, whereas blood group AB is least common among the populations of Eastern Uttar Pradesh region. To test if our sampling had covered the representative blood group distribution of this region, we referred to the published data of the same region [36][37][38][39][40][41][42][43] and performed a regression analysis. The adjusted R square value (83.6 % +3.4 %) demonstrated significantly high level of correlation between our data as well as published data, suggesting that our sampling indeed represented the regional distribution of the blood groups.…”

“…1). We have also collected blood group data of the same region for comparison from published sources [36][37][38][39][40][41][42][43].…”
