The (near) complete sequence of a human genome
The Telomere-to-Telomere (T2T) consortium is proud to announce our v1.0 assembly of a complete human genome. This post briefly summarizes our work over the past year, including a month-long virtual workshop in June, as we strove to complete as many human chromosomes as possible. Our progress over the summer exceeded our wildest expectations and resulted in the completion of all human chromosomes, with the only exception being the 5 rDNA arrays. Our v1.0 assembly includes more than 100 Mbp of novel sequence compared to GRCh38, achieves near-perfect sequence accuracy, and unlocks the most complex regions of the genome to functional study. We plan to release a series of preprints in the coming months that fully describe our methods and analyses, but due to its tremendous value, we are releasing the assembly immediately.
