2.4 SONOGEN XP
Results of molecular genetics analyses were forwarded to SONOGEN and further processed by its XP expert system. The SONOGEN XP expert system (www.sonogen.eu) provides an interpretation of identified SNPs of the 16 tested genes. Patients are categorized into metabolizer phenotypes by means of established star allele nomenclature [13], and the SONOGEN XP system generates automated recommendations for current and potential future pharmacotherapy based on pharmacogenetic phenotypes and the classification of their clinical relevance according to PHARMGKB (https://www.pharmgkb.org), as well as other available guidelines from CPIC (https://cpicpgx.org) and DPWG (https://upgx.eu/guidelines).
