The CLN5 Disease
Mia-Lisa Schmiedt Mia-Lisa Schmiedt Mia-Lisa Schmiedt The CLN5 disease − RESEARCH protein maturation, RESEARCH The CLN5 disease − protein maturation, trafficking and pathology trafficking and pathology The CLN5 disease −protein maturation, trafficking and pathology and trafficking maturation, The CLN5 disease −protein Neuronal ceroid lipofuscinoses (NCLs) are a group of hereditary neurode- generative disorders primarily affecting children. Characteristics for NCLs are accumulation of autofluorescent storage material, neuronal degenera- tion, motor disturbances, progressive loss of vision and premature death. One member of the NCL family is the CLN5 disease, a late infantile variant phenotype form, caused by mutations in the CLN5 gene. CLN5 encodes a lysosomal protein of unidentified function. This thesis work contributes to the basic understanding of the molecular and cell biological mechanisms underlying CLN5 disease. Real-time PCR studies indicated that Cln5 gene expression increases gradually in the mouse brain with age and its expres- sion is highest in microglia. This thesis project further presents that the CLN5 protein is cleaved in the ER, trimmed and finally traffics to lysosomes. CLN5 constructs carrying different disease causing mutations revealed that trafficking is disturbed with varying severity depending on the particular mutation. Also, this work provides novel aspects about the early events in the pathogenesis of CLN5 disease, late infantile variant, links Cln5 to lipid metabolism and strengthens the recently reported -

We utilized an informatics-based approach to develop a transcriptional signature of β-cell GA stress using existing RNA sequencing and microarray datasets generated using human islets from donors with diabetes and islets where type 1(T1D) and type 2 diabetes (T2D) had been modeled ex vivo. To narrow our results to GA-specific genes, we applied a filter set of 1,030 genes accepted as GA associated. -

Infantile NCL (INCL), the most severe form of NCL, is caused by mutations in the Ppt1 gene, which encodes the lysosomal enzyme palmitoyl-protein thioesterase 1 (Ppt1). We generated mutations in the Ppt1 ortholog of Drosophila melanogaster in order to characterize phenotypes caused by Ppt1-deficiency in flies. -

Received: 6 July 2020; Accepted: 7 August 2020; Published: 27 August 2020 Abstract: GM2 gangliosidoses are a group of pathologies characterized by GM2 ganglioside accumulation into the lysosome due to mutations on the genes encoding for the β-hexosaminidases subunits or the GM2 activator protein. Three GM2 gangliosidoses have been described: Tay–Sachs disease, Sandhoff disease, and the AB variant. Central nervous system dysfunction is the main characteristic of GM2 gangliosidoses patients that include neurodevelopment alterations, neuroinflammation, and neuronal apoptosis. Currently, there is not approved therapy for GM2 gangliosidoses, but different therapeutic strategies have been studied including hematopoietic stem cell transplantation, enzyme replacement therapy, substrate reduction therapy, pharmacological chaperones, and gene therapy. -

Bioinformatics Classification of Mutations in Patients with Mucopolysaccharidosis IIIA
Metabolic Brain Disease (2019) 34:1577–1594 https://doi.org/10.1007/s11011-019-00465-6 ORIGINAL ARTICLE Bioinformatics classification of mutations in patients with Mucopolysaccharidosis IIIA Himani Tanwar1 & D. Thirumal Kumar1 & C. George Priya Doss1 & Hatem Zayed2 Received: 30 April 2019 /Accepted: 8 July 2019 /Published online: 5 August 2019 # The Author(s) 2019 Abstract Mucopolysaccharidosis (MPS) IIIA, also known as Sanfilippo syndrome type A, is a severe, progressive disease that affects the central nervous system (CNS). MPS IIIA is inherited in an autosomal recessive manner and is caused by a deficiency in the lysosomal enzyme sulfamidase, which is required for the degradation of heparan sulfate. The sulfamidase is produced by the N- sulphoglucosamine sulphohydrolase (SGSH) gene. In MPS IIIA patients, the excess of lysosomal storage of heparan sulfate often leads to mental retardation, hyperactive behavior, and connective tissue impairments, which occur due to various known missense mutations in the SGSH, leading to protein dysfunction. In this study, we focused on three mutations (R74C, S66W, and R245H) based on in silico pathogenic, conservation, and stability prediction tool studies. The three mutations were further subjected to molecular dynamic simulation (MDS) analysis using GROMACS simulation software to observe the structural changes they induced, and all the mutants exhibited maximum deviation patterns compared with the native protein. Conformational changes were observed in the mutants based on various geometrical parameters, such as conformational stability, fluctuation, and compactness, followed by hydrogen bonding, physicochemical properties, principal component analysis (PCA), and salt bridge analyses, which further validated the underlying cause of the protein instability. Additionally, secondary structure and surrounding amino acid analyses further confirmed the above results indicating the loss of protein function in the mutants compared with the native protein. -

The MPS's are caused by a deficiency of lysosomal enzymes required for the degradation of mucopolysaccharides or glycosaminoglycans (GAGs) within the lysosome [1]. When functioning normally, the lysosomal enzymes break down these GAGs, however when the enzyme is deficient, the GAGs build up in the lysosomes causing damage to the body's tissues. The MPS's share a chronic progressive course with multisystem involvement and characteristic physical features such as coarse facies, hypertelorism, and coarse hair. The MPS patients are also characterized by developmental regression, hepatosplenomegaly and characteristic laboratory and radiographic abnormalities. Clinical features of MPS III are similar to other MPS's and include hyperactivity, aggressiveness, and developmental delays in childhood. Mental abilities decline as the disease progresses. Involvement of other organ systems tends to be mild and dysmorphic features are more subtle than those observed in other type of mucopolysaccharidosis [1]. MPS III is caused by a deficiency of any of four lysosomal membrane enzymes, which leads to impaired degradation of heparan sulfate. The forms of MPS III are clinically indistinguishable each other and are caused by mutations in distinct genes. All four forms of MPS III result in buildup of the same GAG, heparin sulfate. -
