Next Generation Sequencing (NGS) is an interesting technology for PGx

A nice overview of the Requirements for comprehensive pharmacogenetic genotyping platforms was published by _Volker Lauschke et al._ They claim that rare variants account for 30-40% of functional variability in PGx. However they argue that pre-emptive PGx should only include validated variants.

Challenges

  • Short read NGS requires a priori knowledge of likelihood of particular haplotypes. _In silico_ haplotype estimation can e.g. be performed by Beagle.
  • Variants in homologous regions are hard to capture.
