Eight Short tandem repeat markers included in the International Society for Animal Genetics panel of 24 loci investigated in canine comparison tests were analysed in a sample of pure-breed dogs, with the purpose of defining an allele nomenclature based on the number of repeats. A regression analysis of the raw data produced by the sequencer, coupled with the direct sequencing of selected alleles, allowed us to propose a system of nomenclature for six of the eight loci (four di-nucleotidic: AHT121, AHTh137, REN169018 and REN64E19, and two tetra-nucleotidic: FH2001 and FH2328). The remaining two loci (INU055 and FH2848) showed a pattern of fragments that did not resolve in a simple allele series. This work may be useful to establish a basis for comparing data across different laboratories for a set of validated canine markers, which can be used in population genetics, forensics and other analyses.

Abstract
Eight Short tandem repeat markers included in the International Society for Animal Genetics panel of 24 loci investigated in canine comparison tests were analysed in a sample of pure-breed dogs, with the purpose of defining an allele nomenclature based on the number of repeats. A regression analysis of the raw data produced by the sequencer, coupled with the direct sequencing of selected alleles, allowed us to propose a system of nomenclature for six of the eight loci (four di-nucleotidic: AHT121, AHTh137, REN169018 and REN64E19, and two tetra-nucleotidic: FH2001 and FH2328). The remaining two loci (INU055 and FH2848) showed a pattern of fragments that did not resolve in a simple allele series. This work may be useful to establish a basis for comparing data across different laboratories for a set of validated canine markers, which can be used in population genetics, forensics and other analyses.File | Dimensione | Formato | |
