Genetic solutions.
Preexisting genetic solutions from prior studies were known for 211 of the 799 participants included in these analyses. Of the remaining 588 participants, sequencing of banked DNA samples, which generally were in storage for 15–30 years, was highly successful. Of the 588 participants without existing solutions, 554 out of 588 (94%) had usable DNA samples available, which were used for next-generation sequencing (
