Generation of two human iPSC lines from fibroblasts of BPAN patients carrying pathogenic variants in the WDR45 gene.

Stem cell research2026 Feb

Beta-propeller Protein-Associated Neurodegeneration (BPAN) is a rare X-linked dominant disorder (ORPHA:329284) characterized by brain iron accumulation, developmental delay, seizures, motor dysfunction, and progressive neurodegeneration. It results from pathogenic variants inWDR45, encoding WDR45/WIPI4, a key autophagy protein. No curative treatment exists; management is supportive. As BPAN pathogenesis remains unclear, research aims to elucidate its molecular mechanisms and develop targeted therapies. We generated and characterized two induced pluripotent stem cell (iPSC) lines from BPAN patient fibroblasts, providing essential models for studying disease mechanisms and developing effective therapeutic strategies.

A dwdr45 knock-out drosophila model to decipher the role of autophagy in BPAN.

Human molecular genetics2026 Feb 10

Beta-propeller protein-associated neurodegeneration (BPAN) is a rare neurological disorder characterized by severe cognitive and motor impairments. BPAN is caused by de novo pathogenic variants in the WDR45 gene on the X chromosome. WDR45 gene encodes the protein WDR45/WIPI4, a known regulator of autophagy. A defective autophagy has been observed in cellular models of BPAN disease and is associated with neurological dysfunctions in wdr45 knockout (KO) mice. However, it remains unclear whether the autophagic defect directly contributes to all WDR45 loss-induced phenotypes or whether other WDR45-dependent cellular functions are involved. To investigate this, we generated a CRISPR/Cas9-mediated KO of CG11975 (dwdr45 KO), the Drosophila homolog of WDR45. Our analysis revealed that dwdr45 KO flies display BPAN-like phenotypes, including impaired locomotor function, seizure-like behavior, autophagy dysregulation and iron dyshomeostasis. Additionally, dwdr45 KO flies exhibit shortened lifespan compared to control flies. These findings demonstrate that dwdr45 KO fly is a relevant in-vivo model for investigating the key cellular and molecular mechanisms underlying BPAN-associated phenotypes. Here we showed that induction of autophagy in dwdr45 KO flies improved both the shortened lifespan and the seizure-like behavior, but did not restore locomotor function. This suggests that defective autophagy contributes to some, but not all, aspects of the phenotypes resulting from loss of dWdr45 function.

A Comprehensive Overview of the Clinical, Electrophysiological, and Neuroimaging Features of BPAN: Insights From a New Case Series.

Annals of clinical and translational neurology2026 Mar

Neurodegeneration with brain iron accumulation (NBIA) comprises a genetically and clinically heterogeneous group of rare neurological disorders characterized particularly by iron accumulation in the basal ganglia. To date, 15 genes have been associated with NBIA. Among them, WDR45, linked to beta-propeller protein-associated neurodegeneration (BPAN), represents the only X-linked dominant subtype of NBIA. Herein, clinical, electrophysiological, and neuroimaging evaluations were used to broaden the understanding of BPAN in a newly reported case series. This study included 10 individuals with BPAN, categorized into three age groups. WDR45 variant data retrieved from next-generation sequencing or Sanger sequencing were reviewed and reassessed. Comprehensive clinical evaluations including magnetic resonance imaging (MRI), fluorodeoxyglucose positron emission tomography (FDG-PET), and video electroencephalographic monitoring were conducted. The clinical manifestations were highly heterogeneous, with cognitive impairment being a consistent finding among the patients, with variable severity. The associated WDR45 variants are likely to exert loss-of-function effects. Electroencephalogram (EEG) abnormalities included age-dependent background slowing and epileptiform discharges. MRI indicated a characteristic pattern, while two patients lacked these typical findings. FDG-PET imaging demonstrated hypometabolism extending beyond cerebral structures, with predominant cerebellar and pontine involvement in pediatric patients and frontoparietal hypometabolism in adults. This study contributes further to our understanding of the heterogeneous clinical spectrum of BPAN. Genotype-phenotype correlation in BPAN remains unclear due to the absence of sufficiently large cohorts in the literature, including the present study. Nevertheless, even within this small sample, the phenotypic heterogeneity observed among individuals harboring the same genotype highlights the biological complexity of the disease. Neuroimaging findings may reflect progressive and widespread neurological involvement in an age-dependent pattern, whereas EEG data suggest that epilepsy severity tends to decrease after adolescence.

Autophagy and mitophagy at the synapse and beyond: implications for learning, memory and neurological disorders.

Autophagy2026 Jan

The human brain is one of the most metabolically active tissues in the body, due in large part to the activity of trillions of synaptic connections. Under normal conditions, macroautophagy/autophagy at the synapse plays a crucial role in synaptic pruning and plasticity, which occurs physiologically in the absence of disease- or aging-related stressors. Disruption of autophagy has profound effects on neuron development, structure, function, and survival. Neurons are dependent upon maintaining high-quality mitochondria, and alterations in selective mitochondrial autophagy (mitophagy) are heavily implicated in both genetic and environmental etiologies of neurodegenerative diseases. The unique spatial and functional demands of neurons result in differences in the regulation of metabolic, autophagic, mitophagic and biosynthetic processes compared to other cell types. Here, we review recent advances in autophagy and mitophagy research with an emphasis on studies involving primary neurons in vitro and in vivo, glial cells, and iPSC-differentiated neurons. The synaptic functions of genes whose mutations implicate autophagic or mitophagic dysfunction in hereditary neurodegenerative and neurodevelopmental diseases are summarized. Finally, we discuss the diagnostic and therapeutic potentials of autophagy-related pathways.Abbreviations: AD: Alzheimer disease; ALS: amyotrophic lateral sclerosis; APP: amyloid beta precursor protein; ASD: autism-spectrum disorder; BDNF: brain-derived neurotrophic factor; BPAN: β-propeller protein associated neurodegeneration; CR: caloric restriction; ΔN111: deleted N-terminal region 111 residues; DLG4/PSD95: discs large MAGUK scaffold protein 4; ER: endoplasmic reticulum; FTD: frontotemporal dementia; HD: Huntington disease; LIR: LC3-interacting region; LRRK2: leucine rich repeat kinase 2; LTD: long-term depression; LTP: long-term potentiation; MAP1LC3/LC3: microtubule associated protein 1 light chain 3; OMM: outer mitochondrial membrane; PD: Parkinson spectrum diseases; PGRN: progranulin; PINK1: PTEN induced kinase 1; PRKA/PKA: protein kinase cAMP-activated; PtdIns3P: phosphatidylinositol-3-phosphate; p-S65-Ub: ubiquitin phosphorylated at serine 65; PTM: post-translational modification; TREM2: triggering receptor expressed on myeloid cells 2.

WDR45 deficiency shortens axon length in dopaminergic neurons from patient-derived iPSCs.

Human molecular genetics2025 Oct 14

β-propeller protein-associated neurodegeneration (BPAN) is characterized by global developmental delay, intellectual disability, and epileptic encephalopathies in infancy or early childhood caused by WDR45/WIPI4 gene mutations. WDR45 depletion disrupted autophagy, leading to iron accumulation in the brain and contributing to neuronal apoptosis. The impact on neuron performance remains unknown. Our previous study established the iPSC cell line derived from a girl patient with a de novo variant c.344 + 5G > T in WDR45 (FDHPIi001). This study demonstrated that this intron 6 mutation impairs RNA splicing, resulting in a 28 bp insertion and nonsense-mediated mRNA decay (NMD) of truncated WDR45. Upon differentiating the iPSCs into dopaminergic neurons, we observed significantly shorter neuronal axons using high-intensity imaging analysis. Additionally, there was significant ferritin accumulation in the induced neurons but not in the iPSCs from the same patient. This research has elucidated the pathogenicity of a non-canonical splice site mutation in WDR45 and has provided deeper insights into the pathologies of neurodegenerative diseases caused by WDR45 defects.
