Reversible white matter changes following a 4‐week high phenylalanine exposure in adults with phenylketonuria

 Published on 14/03/2025 |  Original article (Abstract)  | Raphaela Muri et al. | Journal of inherited metabolic disease 2024; AOP: 10.1002/jimd.12823

This dysfunction elevates Phe levels in the blood and brain, causing severe intellectual disabilities if dietary management during childhood is inadequate or insufficiently stringent....

Plasma DNA Methylation‐Based Biomarkers for MPNST Detection in Patients With Neurofibromatosis Type 1

 Published on 07/03/2025 |  Original article (Abstract)  | Katarzyna Tomczak et al. | Molecular Carcinogenesis 2024; AOP: 10.1002/mc.23825

Neurofibromatosis 1 (NF1) entails a constellation of clinical manifestations, including the proliferation of neural tissues that leads to both benign and malignant tumors. In 8%–6% of individuals with NF1, some benign neurofibromas progress to become malignant peripheral nerve sheath tumors (MPNSTs)....
