T2T Consortium Completes Full Diploid Human Genome Reconstruction
The T2T Consortium has successfully reconstructed the first complete diploid human genome, mapping both sets of chromosomes from each parent. This advancement improves the accuracy of genomic analysis and supports the future of precision medicine.
Why it matters
Completing the human genome map removes gaps in previous reference models, enabling more precise diagnostic capabilities for genetic diseases.
Two decades after the human genome project, researchers from the Telomere-to-Telomere (T2T) Consortium have reconstructed the complete human genome, with full sets of chromosomes from each parent, a breakthrough that will accelerate research, improve diagnostic accuracy, and make precision medicine routine in medical care.
The work, led by Johns Hopkins University, the National Human Genome Research Institute, and the National Institute of Standards and Technology (NIST), builds on the 2022 completion of the first human genome by the T2T Consortium.
That project filled in the last eight percent of a single genome, but the current study, published in Cell , goes further by reconstructing complete diploid genomes, meaning each genome contains two slightly different copies of every chromosome, with one copy inherited from each parent.
