STR

Definition

A short tandem repeat region whose variants can be compared using an appropriate typing method. A locus is a specified genomic region. A marker name alone does not establish a person or mixture contribution.

Context
Genetic markers

For example, repeat-number variation at selected loci can support genetic comparison while mixture and artefact interpretation remain necessary.

Assay performance, population information and interpretation methods remain necessary.
