X-chromosome in Italy: A database of 29 STR markers

We collected published and unpublished data from 17 contributing groups participating in the GeFI (Italian Forensic Geneticists). The total number of typed subjects was 1114 males and 777 females, coming from 11 regions of North, Centre, and South Italy, and Sardinia. Individual's multilocus genotypes included 4–12 loci. The total number of typed markers was 29, scattered along the X-chromosome genetic map in several clusters; the most used marker was DXS7423 (2429 gene copies); the mean number of subjects typed per marker was 336 for males and 208 for females. Data are available online.
