This will be fantastic (not just because I am helping to organise it)! An amazing line up of speakers and topics. Hope to see you there!

Implications:
✅ Considering HLA context in research and clinical risk prediction
✅ A need for models integrating monogenic, APOL1, HLA, PRS, and environment

This work also won the @roysocmed.bsky.social Stewart Cameron Science Award 2025!

💡 Big picture:
Kidney failure risk can come from innate injury (APOL1) + adaptive immune predisposition (HLA).
The convergence of these pathways may explain why some patients progress rapidly to kidney failure without clear cause.
The genetic architecture of uKF is different to other CKD causes.
oalavijeh.bsky.social
When we zoomed in on HLA in UK Biobank + 100KGP, we found:
👉 HLA-DQB1*03:19 strongly enriched in APOL1 carriers with early kidney failure (OR ~24, p=0.001) and West Africa!
oalavijeh.bsky.social
Those with high-risk APOL1 also had:
🔹 Elevated steroid-sensitive nephrotic syndrome (SSNS) polygenic risk score
🔹 Signal driven by the HLA region

This suggested a second “immune hit.”
oalavijeh.bsky.social
Among patients of African ancestry, high-risk APOL1 was hugely enriched:
📈 52% in uKF vs 8% in ancestry-matched controls.
Odds ratio ~9.

So APOL1 alone explains a lot. But we noticed something more…
oalavijeh.bsky.social
Unexplained kidney failure (uKF) affects ~15% of patients needing dialysis/transplant.
We used whole-genome sequencing + large-scale case-control analyses (218 cases, >26k controls) to dissect the genetic architecture.

👉 17% of cases had a monogenic diagnosis (COL4A, NPHP1, etc).

🫀 #Hypertension in autosomal dominant polycystic kidney disease: unique pathways, common consequences.
In #ADPKD, high blood pressure is often the first clinical sign and not just a complication of the kidney disease.
Actually its mechanisms differ markedly from other CKD-related hypertension... 🧵

A paper in Nature reports whole-genome sequences for 490,640 participants from the UK Biobank and combines these data with phenotypic data to provide new insights into the relationship between human variation and sequence variation. go.nature.com/415CMhr 🧬 🧪
This is figure 1, which shows the variant call sets.

Last week I was taking someone through the basics of human GWAS - that the fundamental model is simple (sooo simple!) but the complications are (a) population stratification and (b) multiple testing.

📣 Latest from the lab: Performance of deep-learning-based approaches to improve polygenic scores www.nature.com/articles/s41...

Its thought deep learning will substantially improve PGS but the reality is MANY have tried but no/little gain has been seen so far. Here we report our negative results.

🧬 WGS at birth
Whole genome sequencing of newborns enables early detection of Alport, ADPKD, IgA nephropathy + more.
Long-term, CRISPR could offer cures.

📲 Remote, AI-powered follow-up
Wearables monitor cfDNA, proteinuria & other biomarkers at home. AI flags early signs of rejection before symptoms show.

🧪 Immunosuppression reimagined
T cell therapies mean some patients won’t need lifelong drugs. Less toxicity, better graft survival.

🐷 Xenotransplantation enters the chat
Gene-edited pig kidneys are being trialled in humans now. By 2050, they may help patients with no living/cadaveric match.

🧬 Transplant demand skyrockets
We may need 200,000 kidney transplants a year in the UK by 2050. Transplant nephrology will be a specialty in its own right.

🌍 Dialysis gets greener
Dialysis uses a lot of water and plastic. In 2050? Wearable, water-recycling, sorbent-based tech is mainstream. Less waste, more independence.

👶 Prevention starts early
In 2050, obesity, diabetes and CKD prevention begin at school. National GLP-1 + lifestyle programmes are the new norm.
