Title: Addressing Y-Chromosome Short Tandem Repeat(Y-STR) Allele Nomenclature
Published: November 25, 2008
Abstract: Currently 120 different Y-chromosome short tandem repeat (Y-STR) markers are used by various genetic genealogy testing laboratories. In some cases, different laboratories may designate the same Y-STR allele with two different nomenclatures making data comparisons difficult and frustrating due to needed conversion factors. This article explains how STR allele nomenclatures are typically determined, where ambiguity may exist, and how measurement accuracy and consistency can be promoted through use of common reference materials across all genetic genealogy testing laboratories. Comparisons are made to forensic DNA testing and the benefits of a common set of loci and STR allele nomenclatures.
