Resumen:
We typed 1541 Y-STR haplotypes from reference samples along forensic casework investigations. In threehaplotypes, we detected a variant allele designed as 16.3 at locus DYS533. This was confirmed by amplificationusing two commercial kits. Sanger sequencing revealing a novel motif corresponding to [TATC]12 repeats with a19-bp insertion in the flanking upstream region. We propose its origin as an insertion at 9.1 upstream of therepeat motifs. We searched other local databases and found this allele in various geographical areas of Argentinaand neighbouring countries. The haplotypes share a common core of 10 Y-STRs (DYS389-I/13; DYS389-II/30;DYS19/14; DYS481/22; DYS438/12; DYS437/16; DYS635/23; DYS392/13; DYS393/13; GATA H4/11) andbelong to the R1b haplogroup. This 16.3 allele is restricted to southern South America, which allows us topropose a local and relatively recent origin. The sequence described herein constitutes a novelty that could beconsidered in future criteria for the nomenclature of STRs based on massively parallel sequencing.
