Acid Ceramidase Deficiency: New Insights on SMA-PME Natural History, Biomarkers, and In Cell Enzyme Activity Assay.
Spinal muscular atrophy with progressive myoclonic epilepsy (SMA-PME) due to acid ceramidase deficiency is a rare disorder, allelic with Farber disease, resulting from recessive ASAH1 variants. Patients present in early childhood with muscle weakness due to anterior horn degeneration and/or progressive drug-resistant myoclonic epilepsy. Death usually results from respiratory complications or status epilepticus during adolescence. We identified 9 patients with SMA-PME from 5 different families followed in neurology, rehabilitation, and genetics departments of university hospitals in France and the United States. During disease progression, motor functional scores were assessed for seven of them and C26-ceramide quantification on dried blood spots (DBSs) was performed for 4 of them. An in cell assay, measuring the degradation rate of ceramides in living skin fibroblasts, was also performed in 2 patients. Finally, a literature review was conducted. Twelve years after the molecular characterization of SMA-PME, here we present the detailed history of 9 patients from 5 different families with 4 new ASAH1 variants. The prospective follow-up for 4 of them allows us to evaluate the relevance of functional scales and of C26-ceramide assay on DBS, as a biomarker. In addition, an in cell assay could provide a more reliable level of the residual ceramidase activity. Based on a comprehensive literature review, we provide a detailed description of the natural history of the 44 patients with SMA-PME diagnosed to date and show a genotype-phenotype correlation for the 2 main variants and the disease onset. This study presents the detailed natural history of SMA-PME. Given the rarity of this disease and the current lack of a reliable biomarker for patient follow-up, this work may serve as a retrospective control group for future therapeutic trials.
Endocannabinoid receptor 2 is a potential biomarker and therapeutic target for the lysosomal storage disorders.
Herein, we studied the expression of endocannabinoid receptor 2 (CB2R), a known inflammation mediator, in several lysosomal storage disorder (LSD) animal models and evaluated it as a potential biomarker and therapeutic target for these diseases. CB2R was highly elevated in the plasma of Farber disease and mucopolysaccharidosis (MPS) type IIIA mice, followed by Fabry disease and MPS type I mice. Mice with acid sphingomyelinase-deficient Niemann-Pick disease (ASMD) and rats with MPS type VI exhibited little or no plasma CB2R elevation. High-level expression of CB2R was also observed in tissues of Farber and MPS IIIA mice. Treatment of MPS IIIIA patient cells with CB2R agonists led to a reduction of CB2R and monocyte chemoattractant protein-1 (MCP-1), a chemotactic factor that is elevated in this LSD. Treatment of MPS IIIA mice with one of these agonists (JWH133) led to a reduction of plasma and tissue CB2R and MCP-1, a reduction of glial fibrillary acidic protein (GFAP) in the brain, and an improvement in hanging test performance. JWH133 treatment of Farber disease mice also led to a reduction of MCP-1 in tissues and plasma, and treatment of these mice by enzyme replacement therapy (ERT) led to a reduction of plasma CB2R, indicating its potential to monitor treatment response. Overall, these findings suggest that CB2R should be further examined as a potential therapeutic target for the LSDs and may also be a useful biomarker to monitor the impact of therapies.
Broadening the mutational spectrum of ASAH1, as a susceptibility gene for keloids.
Keloids are fibroproliferative scars influenced by genetic predisposition, notably involving the ASAH1 gene, which encodes acid ceramidase. A prior study identified a pathogenic ASAH1 variant (NM_004315.6:c.1202 T > C;NP_004306.3:p.(L401P)) in a Yoruba family with keloids. To investigate ASAH1 variant prevalence, we screened 291 Black patients with keloids in the Genetic Causes of Keloid Formation Study. Although the original variant was not detected, four novel rare ASAH1 variants were identified. None of the four were present in 718 race-matched controls. Functional predictions using SIFT and PolyPhen were used to predict which rare variants may be damaging. ASAH1 dysfunction is implicated in Farber disease, a lipid storage disorder affecting wound healing. These findings support further investigation into ASAH1's role in keloid pathogenesis and the development of personalized therapeutic approaches.
Cardiac dysfunction and altered gene expression in acid ceramidase-deficient mice.
Farber disease (FD) is an ultrarare, autosomal-recessive, lysosomal storage disorder attributed to ASAH1 gene mutations. FD is characterized by acid ceramidase (ACDase) deficiency and the accumulation of ceramide in various tissues. Classical FD patients typically manifest symptoms including lipogranulomatosis, respiratory complications, and neurological deficits, often leading to mortality during infancy. Cardiac abnormalities in several FD patients have been described; however, a detailed examination of cardiac pathology in FD has not been conducted. Here we report pronounced cardiac pathophysiology in a new P361R-FD mouse model of ACDase deficiency that we generated. P361R-FD mice displayed smaller hearts, altered cardiomyocyte architecture, disrupted tissue composition, and inclusion-containing macrophages. Echocardiography suggested ventricular atrophy, valve dysfunction, decreased cardiac output, and lowered stroke volumes. Troponin I was significantly elevated in P361R-FD mice. Hearts from P361R-FD mice were found to have increased ceramide, cholesterol, and other lipids. Histopathological analysis of heart tissue from neonatal P361R-FD mice revealed lysosomal disruption as early as postnatal day 1. Finally, we report cardiac conduction, striated muscle contraction, and sphingolipid homeostasis gene expression differences during cardiac development in P361R-FD mice. In summary, we investigated the heart in a mouse model of ACDase deficiency, demonstrating that ACDase deficiency induced lysosomal dysfunction, sphingolipid and cholesterol imbalances, tissue disruption, and significant inflammation, leading to impaired cardiac function in these animals.NEW & NOTEWORTHY This is the first characterization of cardiac function and histopathology in a mouse model of acid ceramidase deficiency. We report physiologic disruption suggestive of heart failure with preserved ejection fraction, progressive histopathology, and aberrant gene expression. We found significant lysosomal disruption at both neonatal and adult ages, suggesting a crucial role of acid ceramidase, and potentially ceramides, in cardiac development and function.
