Researchers Identify 126,018 Human Genetic Variations

Almarri et al present a comprehensive analysis of structural variation in the Human Genome Diversity panel, a high-coverage dataset of 911 samples from 54 diverse worldwide populations, and identify, in total, 126,018 variants, 78% of which were not identified in previous global sequencing projects.

A team of scientists from the Wellcome Sanger Institute, the Francis Crick Institute, and EMBL-EBI has created a comprehensive structural variation atlas for a geographically diverse set of human genomes and recovered sequences missing from the human reference sequence. Among the 126,018 structural variations discovered by the team were medically-important genes in Oceanian populations that were inherited from Denisovans, a sister group to Neanderthals. Almarri...
