A1A2BO and Rh gene frequencies among six populations of Jammu and Kashmir, India

A study was undertaken to record gene frequencies of ABO blood groups, their subtypes and Rh antigen for six different endogamous groups including a tribal population. The ABO phenotypic frequency varies among six different populations showing significant difference (p<0.0005). Gujjar and Bakarwal (a tribal population) shows highest (42.29%) of B blood phenotypes. A1 is the highest among Syeds (39.31%), O blood group frequency highest among Mughals (43.23%) and A1B and A2B are rare phenotypes showing very low frequency among all populations. The pattern of allele frequencies (p<0.025) is in order of I(O)>I(B)>I(A1)>I(A2), except Syeds (I(O)>I(A1)>I(B)>I(A2)). The rhesus protein (Rh) phenotypic frequency (p<0.01) shows significant increase in Rh(D) positive (87.86% in Syed to 96.03% in Khan) among all populations. The Rh allele (p<0.05) and genotype (p<0.02) frequencies shows a significant difference. Heterozygosity for Rh protein is less than homozygosity among six populations. The result from this study provides information on the genetic variation in blood antigens and rhesus protein among human populations inhabiting Jammu and Kashmir.

Microsatellite variation and allele frequency distribution for (TPOX) STRS locus in North Indian Muslim populations

Materials and methods The DNA was extracted from blood samples by using the standard phenol-chloroform extraction method and then amplified by PCR using specific primers for TPOX locus. The PCR products were separated by electrophoresis on denaturing 6% polyacrylamide gel and silver staining was done to resolve and observe different alleles. The observed and expected heterozygosity (Hobs and Hexp) as well as forensic and paternity indices including matching probability (MP), power of discrimination (PD), power of exclusion (PE) and polymorphism information content (PIC) were calculated using the Power Stats v.1.2 software for TPOX locus of the studied population. The POPGENE (v.32) statistical package was used for analyzing allele frequency.
