Completing a human reference genome

What the research found

The Telomere-to-Telomere Consortium reported a 3.055-billion-base-pair human genome assembly, filling major gaps in earlier references. The CHM13 assembly included previously difficult repetitive regions and complete assemblies of all chromosomes except Y. This was a major resource for studying genetic variation and genome organisation.

Where the evidence stops

Completing a reference sequence does not mean that every DNA region has been functionally understood. A reference genome also cannot represent all human diversity or determine an individual’s future health on its own.

The private-client perspective

Private genomic services should distinguish reading DNA, interpreting variants and making medical decisions. Those are separate tasks with different error rates and evidence requirements. Before commissioning testing, clients should understand the purpose, possible incidental findings, privacy implications and the support available for interpretation. More data can be valuable, but only when the service provides a responsible route from information to action.
