How do genetic variants affect secreted proteins?
A new study introduces MultiSTEP, a scalable method for measuring variant effects in coagulation factor IX. The approach assessed >8,500 F9 missense variants and helped reclassify 63.1% of VUSs.

Multiplex and multimodal mapping of variant effects in secreted proteins via MultiSTEP - PubMed
Despite widespread advances in DNA sequencing, the functional consequences of most genetic variants remain poorly understood. Multiplexed assays of variant effect can measure the function of variants at scale but cannot readily be applied to the ~10% of human genes encoding secreted proteins. Here w …
