Automated variant classification has compressed a workflow that used to be measured in weeks. At several centers running rapid pipelines for critically ill newborns, the interval from sample to interpreted result is now under twenty-four hours, with machine classification handling the bulk of the annotation and a genetic counselor reviewing the shortlist.

The clinical consequence is not simply speed. It changes which patients get sequenced. When turnaround was three weeks, sequencing was reserved for cases where the diagnosis would still matter three weeks later. At twenty-four hours, it becomes a diagnostic test used in the acute window, which is a different indication with a different evidence base.

Genetic counselors describe the resulting workload shift bluntly. The interpretation is faster; the conversation is not. Counseling capacity has become the rate-limiting step at every center we spoke with, and it is a role that takes two years to train and does not automate.

Several programs have begun triaging counseling by result category, with negative and clearly benign findings handled through a structured written pathway. Outcomes data on that approach is not yet available.
