February 28, 2025 was Rare Disease Day. To mark this day, the University Hospital of Tübingen made a short video together with Axel Lankenau, father of two sons with PCH2.
Artist with PCH2 “My name is Damien and I am a disabled artist.” This is how 29-year-old Damien from Canada introduces himself on his website. But Damien doesn’t just have…
Finally, on 27 August 2024, the time had come for us, the PCH FAMILY, to set sail from Kiel on board the AIDAnova. One week of cruising the Kattegat and Skagerrak lay ahead of us, and nobody could begin to imagine the experiences we would have together.
Pontocerebellar hypoplasia (PCH), a rare neurodevelopmental disorder, is associated with changes in genes coding for the tRNA splicing endonuclease (TSEN). This multicomponent enzyme is involved in generating essential building blocks for protein synthesis, a process that is crucial to establish and maintain the function of healthy cells. TSEN is found in every cell of the human body but the effect of the PCH-linked mutations only manifests in specific regions of the brain; a phenomenon not understood at all yet.
In their recently published preprint “Brain morphometry and psychomotor development in children with PCH2A”, Pretzel et al. analyzed 78 brain MRIs from a total of 57 children with PCH2A.
Our aim is to use cerebellar and cerebral organoids to recreate PCH2 under laboratory conditions. With a suitable model of PCH2, we can then find out whether and in what way cells with PCH2 differ from healthy cells.
