#CLN2
My little sister, Caitlin, should have turned 30 today. She died, aged just 9, in 2005, from the CLN2 strain of Batten disease, a very rare neurodegenerative disease. Caitlin was my world. If you would like to know more about this devastating disease, please consider visiting www.bdfa-uk.org.uk 🧡🧡🧡🧡

A friend who is also a member of the Rivian community asked if I could share a charity auction for his niece’s charity to find a cure for CLN2 & Batten disease.

CLN2 disease is a childhood-onset neurodegenerative lysosomal storage disorder caused by TPP1 deficiency, but little is known about the cellular cause.

Gentherapie gegen Kinderdemenz: Humane Netzhautmodelle ebnen Weg für klinische Studien
Ein Forschungsteam des Universitätsklinikums Tübingen hat einen bedeutenden Fortschritt in der Behandlung der seltenen Kinderdemenz CLN2 (Batten-Syndrom) erzielt. Mithilfe von humanen Netzhaut-Organoiden und Retina-on-Chip-Modellen konnte die Wirksamkeit einer Gentherapie des US-Unternehmens Tern Therapeutics nachgewiesen werden, ohne auf Tierversuche zurückzugreifen. Die Therapie zielt darauf ab, den Verlust des Sehvermögens bei betroffenen Kindern zu verhindern und hat bereits den Weg für eine klinische Studie in Großbritannien geebnet.

Some kids are apparently too expensive to treat.

The UK’s National Institute for Health and Care Excellence (NICE) decided it will stop recommending the ONLY approved treatment for CLN2 Batten Disease.

They cite a lack of proof of long-term effectiveness and, surprise, cost.

Obscenely cruel.

Of course, I would love more funding for CLN1 specifically! Still, I’m happy to celebrate others raising awareness — even if CLN2 is in a relatively better position at the moment.
August 12, 2025 at 9:16 PM
Could do with this level of fundraising for CLN1 - CLN2 already has a treatment which is unique for Batten - who are they funding with $1m as that’s approx 1/3 of the cost of a small clinical study.

Recreating pathophysiology of CLN2 disease and demonstrating reversion by TPP1 gene therapy in hiPSC-derived retinal organoids and retina-on-chip
Corti et al. leverage patient hiPSC-derived retinal organoids and retina-on-chip systems to replicate key CLN2 retinal pathologies, including lipofuscin accumulation and cone dysfunction. AAV9-mediated TPP1 gene therapy restores enzyme expression and reduces pathological hallmarks, offering promise for treating CLN2-associated blindness.

If you need some good news today, the B.C. govt reinstated treatment funding for a child with the rare, terminal CLN2 Batten Disease. CLN2 is the only form with an approved treatment so far, and we’re happy she has access again!

And we’re still hoping for cures to other forms of Batten Disease too!

I read the article and that's not what it says. "Once a patient has declined in their motor and language functions by a certain amount, Brineura no longer slows the progression of CLN2." That's why it's not covered any longer. It was covered for 6 years. From age 3 onward.

CLN2 is really rare. As in, there is one kid in BC with this disease. There may never be another one, it's that rare. It's a lot to deal with, but she does. The idea that this decision is a purely neutral, non-financial one is ludicrous in the extreme.

"Charleigh is the only person in B.C. diagnosed w/ #CLN2 #BattenDisease, a rare genetic #neurodegenerative disorder that progressively robs children of their ability to see, speak, walk, and eventually swallow." 👉 Example of #Canada #Healthcare failing those who need the most help.
