Título del trabajo: Y-STR HAPLOTYPE VARIATION IN A SAMPLE FROM BUENOS AIRES (ARGENTINA). Autores: Catanesi C.I., Glesmann L.A., Silbestro M., Vidal Rioja L. Y-STR genotyping is a common procedure to describe male-specific haplotypes in forensic and paternity casework, and strengthen knowledge on population genetic studies. Information on haplotype diversity in every particular geographic region results necessary for reliable case solving. Thus, we analyzed 9 Y-STRs in 89 males from Buenos Aires region, Argentina, sampled for paternity testing in our laboratory. Markersanalyzed were DYS19, DYS389 I, DYS389 II, DYS390, DYS391, DYS392, DYS393, DYS437, and DYS438. We found 76 different haplotypes; with a gene diversity of 0.993. Only 6 haplotypes were present in more than one male, and the most frequent one  (n=6) was DYS19-14, DYS389 I-13, DYS389 II-29, DYS390-24, DYS391-11, DYS392-13, DYS393-13, DYS437-15, and DYS438-12; this one has also been reported as a common haplotype not only in Mendoza province (Argentina), but also in several countries around the world, as described in the Yhrd database. The comparison with this database shows the haplotypes found are mainly shared with individuals from Italy and Spain, as expected from migration history of the country, and also (but in a lower proportion) with Germany, Portugal, Poland, and Czech Republic. Some minor haplotypes are shared with other European countries, Asia and Africa. On the other hand, 36 of the described haplotypes were not present in such database, showing this population as an interesting one for studying genetic diversity.
