In my vision lrGS has the potential to replace all (germline) tests – and truly revolutionize the field of human genetics.
Many thanks who helped to get here. Also many thanks to the entire team @pacbio.bsky.social for many great collaborative efforts.

All of this was enabled by a fantastic team effort over all these years (way too many to mention them all): basic and translational research utilizing lrGS driven together with the research groups led by my amazing long-term collaborators Lisenka Vissers & @christiangilissen.bsky.social!

Also enabled more collaborations on tool development, e.g. 10.0.3.248/j.ajhg.2023....; 10.0.4.162/s12864-023-0...; 10.0.4.77/gr.280060.124
Also with great team of @meberle.bsky.social!

HiFi sequencing accurately identifies clinically relevant variants in paralogous genes
Short-read sequencing (SRS) methods have improved the detection of small genetic variants but remain limited in highly homologous genomic regions, such as segmental duplications with gene-pseudogene p...
