Population and mutational assessment of novel repeats in 13RM Y-STRs in unrelated males born in Gilgit, Pakistan

Because they are totally transferred to the future generations until mutations occur, Y chromosome genetic markers are commonly utilised in forensics for the classification of male lineages for criminal justice purposes. The mutation rate of Rapidly Mutating Y-STRs (RM Y-STRs) markers is high. That is not seen in other Y-STRs markers, and they appear to be effective in distinguishing paternally related men. This study aimed to estimate the population and mutational parameters of 13 RM Y-STRs in 13 unrelated males born in Gilgit, Pakistan. Repeat there was no population substructure and strong discriminating capacity in the counts. In this population, there were higher mutation rates with the unusual structure of repeats. More research is needed to better characterize these loci in diverse Pakistani groups.
