When will the first genome-wide association study of more than 1 million African Americans be published?
In recent years, there has been growing interest in diversifying the samples used in studies that train models to predict human traits, including disease, from genetic data. See for instance, two recent studies. This desire is primarily driven by findings that models trained on European-descent populations only generalize imperfectly to other populations, and particularly poorly to African descent populations, including African Americans.
The Genome-Wide Association Study Diversity Monitor shows an overview of GWAS findings broken down by ancestry of participants. A GWAS (genome-wide association study) is a study that attempts to predict a phenotype from genome-wide genetic data, and not just a specific region.
As of writing, 1.4% were African (African American or Afro-Caribbean). The largest listed study with persons of African descent had 68.2k persons, and was published in 2019.
This question asks: When will the first study be published that includes at least 1,000,000 persons of African descent in a GWAS?
For the purposes of this question:
Published studies mean research papers that are open to public readership, or published in a peer-reviewed journal. This includes preprints (e.g. biorXiv), and other open science documents.
Whole exome sequencing, whole genome sequencing, and genome-wide genotyping arrays count.
African American and Afro-Caribbean and other majority African ancestry populations are counted as "African" though they are part non-African ancestry. The data are classified this way in studies.
The question will resolve as >2040 if no such study is published before December 31, 2040.
Metaculus help: Predicting
Predictions are the heart of Metaculus. Predicting is how you contribute to the wisdom of the crowd, and how you earn points and build up your personal Metaculus track record.
The basics of predicting are very simple: move the slider to best match the likelihood of the outcome, and click predict. You can predict as often as you want, and you're encouraged to change your mind when new information becomes available.
The displayed score is split into current points and total points. Current points show how much your prediction is worth now, whereas total points show the combined worth of all of your predictions over the lifetime of the question. The scoring details are available on the FAQ.
Note: this question resolved before its original close time. All of your predictions came after the resolution, so you did not gain (or lose) any points for it.
Note: this question resolved before its original close time. You earned points up until the question resolution, but not afterwards.
This question is not yet open for predictions.
Metaculus help: Community Stats
Use the community stats to get a better sense of the community consensus (or lack thereof) for this question. Sometimes people have wildly different ideas about the likely outcomes, and sometimes people are in close agreement. There are even times when the community seems very certain of uncertainty, like when everyone agrees that event is only 50% likely to happen.
When you make a prediction, check the community stats to see where you land. If your prediction is an outlier, might there be something you're overlooking that others have seen? Or do you have special insight that others are lacking? Either way, it might be a good idea to join the discussion in the comments.
