Variability of the mitochondrial DNA control region in Roma population

In order to determine the effect of isolation on Roma population mtDNA profil in forensic context, the two hypervariable regions – HVS I position 16024-16383) and HVS II (position 57-372) were sequenced and analyzed in 143 Croatian Bayash Roma from Međimurje in Northwestern Croatia and in 190 Croatian Bayash Roma from Baranja in Eastern Croatia. Diversity parametars were calculated. Croatian Bayash Roma were compared with Hungarian Bayash Roma and Iberian Roma. Our data indicate great differences in mtDNA haplotypes distribution and composition between two Croatian Bayash Roma population. This suggests that two Croatian Bayash Roma populations should be considered separately in forensic analysis. All analyzed Roma populations show a low level of mtDNA variability. These results indicate that potential of discrimination of mtDNA in forensic is more limited in isolated populations. Roma and other isolated populations show significant genetic departures and should therefore be treated in forensic with great caution.
