As we move towards a complete map of human variant effects, evaluating VEP and MAVE scores in clinically meaningful ways becomes essential. In work led by Yifei Shang and @jmarshlab.bsky.social, we explore mean evidence strength (MES) to quantify clinical utility after ACMG/AMP calibration.

New preprint on how disagreement among variant effect predictors can help guide prioritization of proteins for experimental analysis

Work led by Nicolas F Jonsson in a collaboration with Joe Marsh.

A structure-guided approach to noncoding variant evaluation for transcription factor binding using AlphaFold 3 Abstract. Noncoding single-nucleotide variants (SNVs) that alter transcription factor (TF) binding can affect gene expression and contribute to disease. Se

Assessing variant effect predictors and disease mechanisms in intrinsically disordered proteins Author summary Some parts of proteins, known as intrinsically disordered regions, do not fold into fixed shapes. Instead, they stay flexible and play key roles in controlling how cells work, often by ...

New paper out today in PLOS Comp Biol:
journals.plos.org/ploscompbiol...

Intrinsically disordered regions make variant prediction deceptively easy for benign changes but very hard for pathogenic ones. Our work shows why current tools struggle here, and why disorder-aware approaches are needed.

We’ve updated the acmgscaler manuscript following reviewer and community feedback.

The R package now has a single calibrate() function, and the Colab interface is easier to use.

The guidelines "aim to streamline VEP development, sharing, and evaluation by tackling data availability, interpretability, transparency, and circularity." Benjamin J. Livesey, @jmarshlab.bsky.social et al

In contrast to suggestions that DMS-based benchmarks might not reflect clinical utility, we demonstrate a striking correspondence between VEP performance in functional assays and clinical variant classification.

Explore the full paper for insights into top-performing VEPs.

Traditional benchmarks often face circularity issues, inflating performance estimates. In this study, led by Ben Livesey, we use deep mutational scanning (DMS) datasets from 36 human proteins to benchmark 97 VEPs, introducing a novel pairwise comparison method for fairer rankings.

Variant effect predictor correlation with functional assays is reflective of clinical classification performance - Genome Biology Background Understanding the relationship between protein sequence and function is crucial for accurate classification of missense variants. Variant effect predictors (VEPs) play a vital role in decip...

Following our variant effect predictor (VEP) guidelines paper last week, we’re excited to announce another publication in Genome Biology today—the latest iteration of our VEP benchmarking efforts.

With so many VEPs released recently, how do we choose the best ones?
