A canine PLP1 missense variant differentiates oligodendrocyte maturation in connatal and classical Pelizaeus-Merzbacher disease.

Proceedings of the National Academy of Sciences of the United States of America2026 Feb 24

Pelizaeus-Merzbacher disease (PMD) is an X-linked hypomyelinating disorder caused by pathogenic variants in the proteolipid protein (PLP1) gene. We report a spontaneous canine dysmyelinating leukodystrophy in English Cocker Spaniel puppies. The most severely affected male pup displayed pronounced generalized tremors, progressive motor dysfunction, and markedly impaired growth. Histopathology at 5 wk of age revealed profound central nervous system (CNS) dysmyelination with no evidence of peripheral nerve involvement. Western blotting confirmed markedly reduced expression of CNS myelin-associated proteins. Ultrastructural analysis demonstrated a near absence of compact myelin, rare myelinated axons, and significant oligodendrocyte abnormalities, the majority of which had an immature cellular morphology. More mature, yet infrequent oligodendrocytes had distended rough endoplasmic reticula. Nucleotide sequence analysis identified a hemizygous c.92T>A missense variant in the PLP1 gene predicted to cause a leucine-to-glutamine substitution in the first transmembrane domain, p.(L31Q). This variant was absent in over 1,600 public canine genomes and was predicted to be deleterious by multiple bioinformatic tools. Heterozygous females exhibited variable, transient clinical signs. We compared this canine leukodystrophy with the previously reported shaking pup and found that it represents a more severe phenotype recapitulating key clinical, pathological, and molecular features of severe connatal PMD in humans, including extreme CNS dysmyelination and associated neurological deficits. Interestingly, this genetic variant seems to cause a defect at the oligodendrocyte progenitor stage limiting subsequent oligodendrocyte maturation and preventing myelination. The identification of this naturally occurring model provides a potential resource for investigating the mechanisms and therapeutic targets for specific PLP1 genetic variants.

The Impact of RNA Polymerase III-Related Leukodystrophy on Nonaffected Family Members: A Qualitative Study.

Pediatric neurology2026 Mar

RNA polymerase III-related hypomyelinating leukodystrophy (POLR3-HLD) is a rare, neurodegenerative, brain white matter disorder characterized by hypomyelination, hypodontia, and hypogonadotropic hypogonadism. Due to the complex and progressive nature of this disorder, parents and siblings of patients face many potential challenges and stressors. We, therefore, sought to explore parents' and siblings' experiences to understand their specific needs and identify modifiable factors to limit familial burden and improve their quality of life. We conducted semistructured interviews with parents and siblings of patients with POLR3-HLD. Interview questions focused on the financial, emotional, and psychosocial impacts on parents, as well as siblings' relationship with their affected sibling and the psychosocial impacts they may have experienced. All interviews were recorded, transcribed, and analyzed using reflexive thematic analysis. Through the coding process, themes surrounding the impact on and experiences of parents and siblings were developed. Nineteen semistructured interviews with 24 parents and nine interviews with 9 siblings were completed between March and October 2023 and February and May 2024, respectively. Four themes from parent interviews included extensive caregiver burden, emotional and psychosocial challenges, the importance of parental self-health, and comfort in the leukodystrophy community. Three themes from sibling interviews included the spectrum of emotional impacts, limited knowledge about POLR3-HLD, and adapting to their sibling's needs. This study provides a comprehensive understanding of the family experience, identifying the common challenges and specific needs of parents and siblings, highlighting areas of improvement in the global care offered to this vulnerable patient population.

Diffusion Tensor Imaging and Fiber Tractography Analysis in Patients with Pelizaeus-Merzbacher Disease.

Noro psikiyatri arsivi2026

Pelizaeus-Merzbacher Disease (PMD) is a hypomyelinating disorder with X-linked recessive inheritance caused by mutations in the proteolipid protein 1 (PLP1) gene on chromosome Xq22. In the early stages of PMD, head tremor and pendular nystagmus are observed, while in the later stages, psychomotor developmental delay, choreoathetosis, ataxia, and spasticity are added to the clinical presentation. This study aimed to investigate the relationship between diffusion tensor imaging-fiber tractography (DTI-FT) findings, the clinical and pathogenetic features in PMD patients. Nineteen patients diagnosed with PMD between 1995-2006 and 19 healthy controls were included in our study. Both patient and control groups underwent 3 Tesla Magnetic Resonance Imaging (MRI), DTI, and FT examinations. By using DTI regions of interest (ROI) were drawn in the corticospinal tract, right inferior occipitofrontal fasciculus (RIOFF), middle cerebellar peduncle, and right cingulum. The mean fractional anisotropy (FA) values of the tractographies which obtained from the ROIs were calculated. Clinical and genetic features were compared with mean FA values. Significant differences were found between the PMD and control groups in the FA values of the corticospinal tract (CST), corpus callosum, right inferior occipitofrontal fasciculus, middle cerebellar peduncle and right cingulum. This patient group had significantly higher FA values. Patients with severe disabilities showed marked reductions in anisotropy at the corticospinal tract level. The significantly reduced FA values in the white matter regions in the patient group are sufficient to suggest predominantly white matter involvement in PMD. The markedly lower CST FA values in patients with severe disabilities indicate that CST may serve as an important localization for determining disease severity. Studies using DTI-FT in similar patient groups will non-invasively enhance our understanding of structural differences.

Mutant PLP1 impairs COPII vesicle formation via ER calcium depletion in Pelizaeus-Merzbacher disease.

Neurobiology of disease2026 Apr

Pelizaeus-Merzbacher disease (PMD) is a devastating, X-linked hypomyelinating leukodystrophy caused by mutations in a myelin gene, PLP1. While overwhelming endoplasmic reticulum (ER) stress caused by the accumulation of mutant PLP1 is widely recognized, blockade of the apoptotic arm of the unfolded protein response (UPR) failed to rescue the phenotypes in murine disease models, suggesting the involvement of additional, critical cellular mechanisms in oligodendrocyte dysfunction. Herein, we identified ER Ca2+ depletion and disrupted ER-Golgi trafficking as key cellular pathologies in PMD. Mutant PLP1 impairs COPII vesicle formation by destabilizing its key components, including Sec31A at ER exit sites due to the Ca2+ transport dysregulation and deconstruction of the ALG-2/Sec31A/AnxA11 interaction. Pharmacological restoration of ER Ca2+ levels rescued COPII formation. These findings highlight how PLP1 mutations affect the intracellular trafficking of membrane and secretory proteins through the ER Ca2+ depletion, which may be associated with the clinical consequences of PMD and other inherited myelin disorders.

Spatially concentrated adenine base editors efficiently correct PLP1 mutations in oligodendrocytes.

Nucleic acids research2026 Feb 24

Oligodendrocytes (OLs), the myelinating cells of the central nervous system, are particularly prone to pathogenic G-to-A mutations, such as PLP1A243V, which causes Pelizaeus-Merzbacher disease (PMD), a lethal hypomyelinating disorder lacking effective therapy. Although adenine base editors (ABEs) can in principle correct such mutations, their application in OLs is limited by inefficient on-target editing. Here, we develop a spatially concentrated ABE (cABE) strategy that enhances editing by promoting nuclear translocation of tRNA adenosine deaminase (TadA*) from the cytoplasm. Using a SunTag-based multivalent recruitment system, TadA* is locally enriched at genomic targets (cABE-1.0), achieving robust editing in vitro. To enable in vivo delivery while preserving high efficiency and fidelity, SpCas9 is replaced with compact eNme2-C Cas9, generating an AAV-compatible variant (cABE-2.0). Notably, cABE-2.0 forms dynamic nuclear puncta with properties of liquid-liquid phase separation, enhancing on-target editing while substantially reducing transcriptome-wide RNA off-target effects. Functionally, cABE-2.0 efficiently corrects the PLP1A243V mutation in OLs, restores Plp subcellular localization, and rescues myelination-related phenotypes. These findings demonstrate that spatial reorganization, rather than increasing intrinsic catalytic activity of TadA*, provides a distinct principle for improving base editing in difficult-to-edit cell types, such as OLs, offering a mechanistic and technical framework for gene therapy of PMD and related myelin disorders.
