A landmark Ōtākou Whakaihu Waka-led study has found the endangered hoiho 🐧 is made up of 3 subspecies, a finding that may help protect the species against fatal disease.
“This is a turning point for hoiho conservation," says senior author Professor Jemma Geoghegan.

My complex variant visualization tool SVTopo is now officially published in BMC Genomics! link.springer.com/article/10.1.... This tool allows HiFi users to view complex germline structural variation in intuitive and informative plots.
Complex structural variant visualization with SVTopo - BMC Genomics
Background Structural variants are genomic variants that impact at least 50 nucleotides. Structural variants can play major roles in diversity and human health. Many structural variants are difficult to interpret and understand with existing visualization tools, especially when comprised of inverted sequences or multiple breakend pairs. Results We present SVTopo, a tool to visualize germline structural variants with supporting evidence from high-accuracy long reads in easily understood figures. We include examples of 101 visually complex structural variants from seven unrelated human genomes, manually assigned to ten categories. These demonstrate a broad spectrum of rearrangement and showcase the frequency of complex structural variants in human genomes. Conclusions SVTopo shows breakpoint evidence in ways that aid reasoning about the impact of multi-breakpoint rearrangements. The images created aid human reasoning about the result of structural variation on gene and regulatory regions.
