The invention entails combining steps of complexity reduction with the introduction of identifiers through ligation or amplification and next-generation sequencing, which allows for highly efficient multiplexed genotyping. Apart from steps of library preparation, the patents cover proprietary elements such as a barcoded 3’-T-overhang adapter and library preparation kits for multiplex genetic variation detection comprising ligation adapters and amplification primers.


The patented technology is the first of its kind to genotype SNP, SSR and indel polymorphisms in a single streamlined process for multiple samples using SBG. Prior knowledge of a reference genome sequence is not required.


Together with the patent family on KeyPoint®, KeyGene’s global SBG portfolio revolutionized the discovery and detection of polymorphisms. The various workflows, kits, and proprietary elements covered by the patents have wide application in medical and agricultural research and diagnostics, ranging from scoring Single Nucleotide Polymorphism (SNP) markers linked to valuable traits in crops and animals to detection of specific mutations associated with human diseases. Examples of such assay methods are described in Truong et al.1, and Poecke et al.2, including related methods such as GBS3, two-enzyme GBS4, tunable GBS5, RAD6, ddRAD7, 2b-RAD8, SLAF-seq9, and hybrid-capture based NGS10.
