Joe Marsh @jmarshlab.bsky.social · 28/09/2026
New preprint from the lab! We used deep mutational scanning to measure the effects of nearly all amino acid substitutions in XPD/ERCC2. Our assay is strongly mechanism-selective, showing better discrimination between different disease phenotypes (TTD vs XP) than any computational predictors.

Mechanism-selective deep mutational scanning distinguishes ERCC2 disease phenotypes
Pathogenic ERCC2 variants cause xeroderma pigmentosum (XP), trichothiodystrophy (TTD) or both, yet variant effect scores are usually interpreted only as measures of pathogenicity rather than of which ...

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.

Prevalence of loss-of-function, gain-of-function and dominant-negative mechanisms across genetic disease phenotypes - Nature Communications
Protein structures can help determine the disease-causing mechanisms of mutations. Here, the authors use a protein structure-based approach to show that nearly half of dominant genetic conditions result in non-simple loss-of-function effects.
