Population data for 8 X-chromosome STR loci in a population sample from Northern Italy and from the Sardinia island

To establish a database for DXS8378, HPRTB, DXS7423, DXS7132, DXS10134, DXS10074, DXS10101, DXS10135 loci in an Italian population sample from Brescia (Northern Italy) and from the Sardinia island, 131 unrelated individuals were typed. DNA was amplified in a multiplex reaction with subsequent automatic detection using capillary electrophoresis. The obtained data give a contribution to the definition of Italian population STR allele frequencies for the eight analysed loci.
