Frequency of ADH 1 B Rsa I ( rs 2066701 ) single nucleotide polymorphism in a population of Bosnia and Herzegovina
Apart from its physiological role in the cellular oxidation of ethanol an interesting feature of ADH1B gene is its characteristic geographical distribution where certain variants of ADH1B peak in different parts of the world. Therefore, ADH1B rs2066701 polymorphism is used as a genetic marker in tracing the evolutionary processes and human migrations over time. Taking into consideration the complexity of population genetic structure and a number of migration events in the history of the Balkan populations this study aimed to estimate the frequency of ADH1B rs2066701 polymorphism in the population of Bosnia and Herzegovina. The total of 101 randomly sampled individuals were genotyped for rs2066701 polymorphism in ADH1B gene using PCR-RFLP method. The obtained frequencies were used to calculate heterozygosity, fixation indices and HardyWeinberg equilibrium. The observed population-structure parameters were compared with other population values available in ALFRED database. Dimensional relations between the investigated populations were visualised with the NM-MDS (non metric multidimensional scaling) analysis using PAST. The minor allele frequency for rs2066701 was 0,257. Inter-population analysis including other European and non-European populations from ALFRED database proved the above-mentioned European genetic background of the B&H population.
