1\ Excited to finally share some of my PhD work: OpenSplice!

We measured how >590,000 mutations affect exon inclusion across 600 human exons, creating a resource to study splicing regulation, benchmark variant effect predictors, and support variant interpretation.

OpenSplice is a powerful resource to help interpret disease-causing variants in the clinic.

Expanding OpenSplice to cover the entire human transcriptome would also allow the development of highly accurate predictive models

Congratulations to the whole team!

Introducing OpenSplice, an atlas of splice-altering variants and the largest systematic analysis of splicing regulatory variants

OpenSplice quantifies the impact of 590,000+ variants on the splicing of 608 alternatively spliced exons, and is out now on bioRxiv 🧬🖥️
