Gong B, Li D, Labaj P, Pan B, Novoradovskaya N, Thierry-Mieg D, et al.
Sci Data . 2024 Aug; 11(1):892. PMID: 39152166
Next-generation sequencing (NGS) has revolutionized genomic research by enabling high-throughput, cost-effective genome and transcriptome sequencing accelerating personalized medicine for complex diseases, including cancer. Whole genome/transcriptome sequencing (WGS/WTS) provides comprehensive insights,...

Zhang Y, Blomquist T, Kusko R, Stetson D, Zhang Z, Yin L, et al.
Genome Biol . 2022 Jun; 23(1):141. PMID: 35768876
Background: Clinical laboratories routinely use formalin-fixed paraffin-embedded (FFPE) tissue or cell block cytology samples in oncology panel sequencing to identify mutations that can predict patient response to targeted therapy. To...
