Non-published variant alleles are being observed on a regular basis as STR typing becomes more wide-spread. To save duplication and to confirm suspicious alleles, these tables are provided for rapid reporting of new variants. When variants are confirmed by sequencing or are published, we include them with the STR fact sheets.
Note: Information regarding variant alleles are submitted by members of the human identity testing community and are listed as provided by the contributor. Allele designations listed in these tables have been determined by comparison to an allelic ladder. Sizes for the same allele may vary for different separation/detection platforms. Off-ladder alleles with a particular STR kit may have corresponding alleles in an allelic ladder from another STR typing kit (e.g., FGA 46.2 is not present in the Profiler Plus kit but is included in the Identifiler kit allelic ladders).
We welcome your contributions in order to more fully catalog the genetic variation observed in these STR loci.
