Targeted Capture of STR Loci by smMIPs

MIPSTR is a method for multiplex genotyping of germline and somatic short tandem repeat (STR) variation across many individuals (Carlson et al., 2015). This method is a variation of the smMIP (Hiatt et al., 2013) approach and uses a novel mapping strategy.

The method uses a smMIP with a common backbone for a PCR primer, sequencing adapters, 12 bp degenerate tag, and targeting arms with locus-specific and STR-flanking sequences. Capture across genetically diverse individuals identifies germline STR variation. The use of degenerate tags identifies technical variation, and STR variation across tag-defined read groups is considered somatic variation.


  • Capable of distinguishing technical error from somatic STR mutations


  • Requires high-quality reference genome
