International Symposium on Human Identification Workshop (Phoenix, AZ - October 2, 2014)


New Autosomal and Y-STR Loci and Kits:

Making Data Driven Decisions


Organized by John M. Butler

National Institute of Standards and Technology


This workshop describes characteristics of additional STR loci that are part of new STR kits created to meet the expanded European and U.S. core loci requirements. Experience is shared with U.S. population data, STR kit concordance studies, issues with validating and implementing new STR kits, benefits of additional Y-STR loci in recent Y-STR kits, and resources available on the NIST STRBase website.
