🚀 Introducing Nucleotide Transformer v3 (NTv3)
Today, we are very excited to share our latest foundation model for biology - Nucleotide Transformer v3 (NTv3).
NTv3 is @instadeepai new multi-species genomics foundation model, designed for 1 Mb, single-nucleotide-resolution prediction, and for bridging representation learning, sequence-to-function modeling, and generative regulatory design within a single framework 🧬
This work was developed in close collaboration with @AlexanderStark8 , @volokuleshov , and @pkoo562 , and reflects several years of joint effort at the intersection of machine learning and regulatory genomics.

Nucleotide Transformer is a series of genomics foundation models of different parameter sizes and training datasets which can be applied to various downstream tasks by fine-tuning. @instadeepai

We were invited to write a review article on DNA/genomic language models (gLMs). We took this occasion to gather our thoughts on promising applications, and major considerations for developing and evaluating gLMs. Pls share with your colleagues: Preprint: arxiv.org/abs/2407.11435

🌱 As scientists wrestled with the mysteries of plant genomics, our #AI problem solvers had a daring question, "Can AI make a difference?" @Nature covered how our #research and AI #genomics teams teamed up to search for an answer, with AgroNT – our new #LLM. 📚Read more→ go.nature.com/3xWopR7

Reposting this criticism of All of Us and their use of ancestry labels
x.com/Graham_Coop/status/162…
30 Jan 2023
The analyses highlighted by the authors risk exacerbating the confusion. Genetic ancestry does not map neatly onto, nor is it highly concordant with these geographic and ethnic categories. 5/n
ALT We evaluated the performance of the ancestry predictions against the self-reported ethnicity of the All of Us samples as ground truth. The performance should be worse than the holdout HGDP samples, but this is expected. Self-reported ethnicity does not correspond to the populations listed above and is prone to false reporting. “Correct” labeling between HGDP/1kg populations and All of Us ethnicities: 1. African (AFR) → Black 2. Latino/Ad Mixed American (AMR) → Hispanic 3. East Asian (EAS) → Asian 4. Finnish (FIN) → White 5. Middle Eastern (MID) → MENA 6. Non-Finnish European (NFE) → White 7. Other (OTH) → Other (do not include skipped) 8. South Asian (SAS) → Asian Based on the procedure above, the concordance between self-reported ethnicity and the ancestry predictions: 0.877

We’re excited to announce the first whole genome screening for embryos is available!
Parents can get 100x more data about their embryos’ genomes, empowering them to make an informed decision and give their baby the best chance at a healthy start.

(1) Pleiotropy: Meaning, a variant at a locus can affect multiple traits simultaneously. Also, pleiotropy can be antagonistic, implying that a variant may be simultaneously harmful AND beneficial. What, then, will these types of screenings be selecting for?

(2) GWAS Transferability: PRS show much greater accuracy in individuals of European ancestry than in others. Thus, the PRS they report may be highly inaccurate for many individuals (admixed/from underrepresented populations) and potentially even irrelevant for some.
