Scientists sequence 100+ individual cells from 74-year-old man, reveal vast genetic chaos including missing chromosomes, deletions, duplications; $140M consortium to map mutations across 150 donors' bodies.

We are all mosaics: vast genetic diversity found between cells in a single person

Human chromosomes (artificially coloured) vary widely from cell to cell, according to an investigation of the DNA in more than 100 cells from a single person. Credit: Cavallini James/BSIP/Science Photo LibraryIn a technological tour de force, researchers have sequenced the whole genomes of more than 100 individual cells from one 74-year-old man. The results exposed chaos within: an extra chromosome arm here, a missing chunk of chromosome there, and smaller snippets of DNA altered, deleted or dup...
