1/8 Our new paper in Nature Communications explores how often pathogenic missense variants cause disease through loss-of-function (LOF), gain-of-function (GOF), or dominant-negative (DN) effects.

1/3 In this work on RyR1, led by Rolando, we (@marshlab.bsky.social) highlight the limitations of using ROC AUC alone to assess clinical utility. Future approaches should consider classification behaviour across the full score distribution.

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.

Disease-associated genetic variants can cause mutations in tissue-specific protein isoforms
Genetic variants can cause protein-coding mutations that result in disease. Variants are typically interpreted using the reference transcript for a gene. However, most human multi-exon genes encode al...

We've developed a method to align genetic variant effect scores with ACMG/AMP classification criteria. It has two key advantages: (1) no assumptions about score distributions, and (2) consistent outputs without user tuning.

So, how many genetic diseases come down to good ol’ loss-of-function in the targeted protein?

Your estimate is probably too high:

Happy to have contributed to this work. As variant effect predictors become increasingly integral to genomic medicine, it is essential that their components and blueprints are accessible to researchers and developers.
New paper out in Genome Biology! 🎉
We lay out best-practice guidelines for releasing variant effect predictors, developed through the Atlas of Variant Effects Alliance @varianteffect.bsky.social

Open, interpretable, and clinically useful VEPs are the goal.

Prevalence of loss-of-function, gain-of-function and dominant-negative mechanisms across genetic disease phenotypes
Molecular disease mechanisms caused by mutations in protein-coding regions are diverse, but they can be broadly categorised into loss-of-function (LOF), gain-of-function (GOF), and dominant-negative (...

Happy to see our predictive scores integrated into DECIPHER! We hope they will help clinicians uncover the molecular mechanisms driving dominant disease. Huge thanks to the team at @deciphergenomics.bsky.social for their support. A follow-up study is underway to improve predictions—stay tuned!
Protein predictive scores which predict the likelihood that the protein is associated with a dominant-negative, gain-of-function or loss-of-function mechanism are displayed. Curated literature support for a molecular disease mechanism is also shown jmarshlab.bsky.social @mbadonyi.bsky.social
