Abstract

Recent progress in deep learning has greatly improved the prediction of RNA splicing from DNA sequence. Here, we present Pangolin, a deep learning model to predict splice site strength in multiple tissues. Pangolin outperforms state-of-the-art methods for predicting RNA splicing on a variety of prediction tasks. Pangolin improves prediction of the impact of genetic variants on RNA splicing, including common, rare, and lineage-specific genetic variation. In addition, Pangolin identifies loss-of-function mutations with high accuracy and recall, particularly for mutations that are not missense or nonsense, demonstrating remarkable potential for identifying pathogenic variants.

  • Sequence-based models of post-transcriptional regulation rely on genome annotations and transformed measurements extracted from RNA-seq to isolate each regulatory mechanism.

    “Similarly, sequence-based models of post-transcriptional regulation rely on genome annotations and transformed measurements extracted from RNA-seq to isolate each regulatory mechanism (for example, percent spliced-in for splicing)14–23.”

    From Predicting RNA-seq coverage from DNA sequence as a unifying model of gene regulation (2025) · cites this paper as [16]

    The Methods section ('Generating training and test sets'; page unavailable) says Pangolin mapped RNA-seq reads using genome annotations and derived splice-site usage labels from those reads. Its training measurement was a Splice-Site Strength Estimate, not percent spliced-in; the paper discusses percent spliced-in for a separate evaluation using minigene assays. The source supports the splicing example in broad terms, but not the specific measurement example or the claim about post-transcriptional models generally. (LLM, conf=0.86)

  • Pangolin has a slight advantage over Borzoi for classifying causal sQTLs from matched negatives (dAUPRC = 0.01, evaluated on all SNPs within distances of ≤10,000 bp from an annotated splice site).

    “When comparing Borzoi to Pangolin16 for the task of classifying the causal sQTLs from matched negatives, Pangolin has a slight advantage (Fig. 7d–e and Supplementary Fig. 12c; dAUPRC = 0.01, evaluated on all SNPs within distances of ≤10,000 bp from an annotated splice site).”
  • Identifying splice sites in DNA sequences has formed the basis for a successful approach to interpreting the splicing code and prioritizing pathogenic splicing variants.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
