Ideally, non profit organizations around tissue sourcing provide a mechanism to ingest raw genotyping data [1] from providers through an auth flow for those who have previously been sequenced or don’t want to burden the charity (if a donor can afford it) with the sequencing cost.
If one could “one click” share their genotyping from from a sequencing provider, I imagine you’d see an uptick in coverage for donor sourcing across the populace. The data is already out there.
