Eeep! I can’t quite believe it! ♥️

Thanks Kaitlin! ♥️

It has been a big day, full of big emotions, but the biggest is the gratitude I feel to all the members of the CRDG, past and present, especially @nickywhiffin.bsky.social, and to @jorisveltman.bsky.social and @margotwyrwoll.bsky.social for already making me feel so welcome!
🧬Exciting times ahead!👩‍💻

I am SO excited to be joining the group of @jorisveltman.bsky.social where together with @margotwyrwoll.bsky.social we will focus on solving challenges in reproductive genomics and genomic medicine, and improving the lives of patients and their families.

In that time, under the phenomenal guidance of @nickywhiffin.bsky.social it has grown into a powerhouse of awesome science, empowerment and joy. I am devastated to be leaving, but am doing so with all the tools and support I need to succeed - a testament to Nicky's skills as a leader and mentor!

It is a big day for me : a 🧵🪡

For the last five years I have had the absolute honour of being a postdoc in the 💜INCREDIBLE🩷 Computational Rare Disease Genomics group at the Nuffield Department of Medicine (@ndm.ox.ac.uk @ox.ac.uk), Uni. of Oxford (@ox.ac.uk).

And a special shout out to the absolutely awesome senior author on this - @ruebenadawes.bsky.social who was a total delight to work with from start to finish!

I would also like to thank all my co-authors for the time, effort and input that has made this a super little bit of work! I'm looking at you @francois-leco.bsky.social Suzi Walker and @nickywhiffin.bsky.social 👀

We would like to thank everyone who has contributed to this work, but most of all the team at Genomics England, all the participants and their families, without whom all this would not have been possible.

We therefore developed a command-line tool, ‘SpliceAI-splint’, to identify the subset of variants for which the precomputed scores may have decreased accuracy, to allow reannotation of a smaller overall variant set. github.com/Computationa...

These findings have real implications for the continued use of precomputed scores. However, despite these issues, precomputed scores still have substantial utility in limiting the computational resources required to identify predicted splice-altering variants.

By correcting these issues we found an increase of 18.2% predicted splice-altering variants compared with variants identified using precomputed scores alone. When assessed using diagnostic variants, updated SpliceAI scores resulted in a diagnostic increase of 11.7%.

Homepage Genomics England analyses sequenced genomes for the NHS and then equips researchers to use data to help find the cause of disease.

To determine the potential impact of these issues we annotated variants in a subset of participants recruited with neurodevelopmental disorders in the @genomicsengland.bsky.social National Genomics Research Library, using both precomputed scores, and SpliceAI with updated parameters.

Precomputed scores were calculated using a distance parameter of 50nt, however the suggested threshold has increased to 500nt. They can’t handle larger insertions and deletions. And there are errors within the file itself, likely arising from conversion of the original annotations to GRCh38.

Unfortunately these scores have limitations that can reduce their accuracy in certain contexts: For example changes in transcript annotations, altered transcript boundaries, absence of annotated genes, and changes to exon composition can mean that scores are missed or altered.

These scores also underlie spliceAI annotations in many variant effect predictors such as the @ensembl.org VEP, forming the basis for annotation in many diagnostic pipelines.

SpliceAI is an invaluable tool to identify splice-altering variants. The provision of precomputed scores for all theoretically possible SNVs, 1 base insertions, and 1-4 base deletions has extended this further, massively reducing the time and cost associated with running spliceAI directly.

Using SpliceAI to triage splice-altering variants in 7,220 individuals with rare conditions highlights limitations of the precomputed scores Background: SpliceAI is a deep learning algorithm that predicts whether genetic variants are likely to affect splicing. Precomputed spliceAI predictions for all theoretical SNVs and small indels were ...

I learned so much from this work and I hope that and discoveries like this can make a real difference to the lives of people living with #RareConditions. Please do share! 😊

An awesome piece of work by @alexblakes.bsky.social, @rociorius.bsky.social, @nickywhiffin.bsky.social and team!

I am super excited to see more emerging from this tiny, but mighty gene, and am overjoyed at the implications this has for the rare disorders community ❤️

The review outlines how UTR variants cause disease, such as:
- Create or remove upstream AUGs (uAUGs)
- Alter splicing
- Alter polyadenylation
- Interfere with miRNA or protein binding

This is such an awesome review paper from @nechamawieder.bsky.social!
UTRs are more than just 'buffers' for the coding sequence - they contain a wealth of important regulatory features!
