What's Happening?
Researchers have published a study in Nature that uses long-read sequencing to reveal previously undetected structural variations in human DNA. The study involved 1,019 individuals from 26 global populations and created over 107,000 sequence-resolved biallelic structural variants. This high-resolution genomic investigation enhances understanding of human genetic diversity and disease potential. The study utilized a novel graph-based analytical framework to map complex DNA insertions, deletions, and rearrangements, providing insights into genetic mechanisms and potential disease management.
