List of Y-STR Markers - Y-STR Allele Nomenclatures

Y-STR Allele Nomenclatures

DNA testing companies or labs in certain cases use different nomenclatures to designate the same Y-STR allele. Thus, a conversion must be applied in these cases to accurately compare Y-STR results obtained from different companies. The most common nomenclature is based on guidance provided by NIST for Y-STR markers historically reported differently by various companies. The NIST standard is the proposal of ISOGG (International Society for Genetic Genealogy) for genetic genealogy companies.
