BACKGROUND:To improve our understanding of urea cycle disorders (UCDs) prospectively followed by two North American (NA) and European (EU) patient cohorts. AIMS:Description of the NA and EU patient samples and investigation of the prospects of combined and comparative analyses for individuals with UCDs. METHODS:Retrieval and comparison of the data from 1095 individuals (NA: 620, EU: 475) from two electronic databases. RESULTS:The proportion of females with ornithine transcarbamylase deficiency (fOTC-D), particularly those being asymptomatic (asfOTC-D), was higher in the NA than in the EU sample. Exclusion of asfOTC-D resulted in similar distributions in both samples. The mean age at first symptoms was higher in NA than in EU patients with late onset (LO), but similar for those with early (≤ 28 days) onset (EO) of symptoms. Also, the mean age at diagnosis and diagnostic delay for EO and LO patients were similar in the NA and EU cohorts. In most patients (including fOTC-D), diagnosis was made after the onset of symptoms (59.9%) or by high-risk family screening (24.7%), and less often by newborn screening (8.9%) and prenatal testing (3.7%). Analysis of clinical phenotypes revealed that EO patients presented with more symptoms than LO individuals, but that numbers of symptoms correlated with plasma ammonium concentrations in EO patients only. Liver transplantation was reported for 90 NA and 25 EU patients. CONCLUSIONS:Combined analysis of databases drawn from distinct populations opens the possibility to increase sample sizes for natural history questions, while comparative analysis utilizing differences in approach to treatment can evaluate therapeutic options and enhance long-term outcome studies.

Mucopolysaccharidosis VI (MPS VI) is a clinically heterogeneous and progressive disorder with multiorgan manifestations caused by deficient N-acetylgalactosamine-4-sulfatase activity. A cross-sectional Survey Study in individuals (n = 121) affected with MPS VI was conducted between 2001 and 2002 to establish demographics, urinary glycosaminoglycan (GAG) levels, and clinical progression of disease. We conducted a Resurvey Study (ClinicalTrials.gov: NCT01387854) to obtain 10-year follow-up data, including medical histories and clinical assessments (n = 59), and survival status over 12 years (n = 117). Patients received a mean (SD) of 6.8 (2.2) years of galsulfase ERT between baseline (Survey Study) and follow-up. ERT patients increased in height by 20.4 cm in the 4-7-year-old baseline age group and by 16.8 cm in the 8-12-year-old baseline age group. ERT patients 200 µg/mg baseline uGAG levels increased FVC by 48% in the

Pulmonary function is impaired in untreated mucopolysaccharidosis type VI (MPS VI). Pulmonary function was studied in patients during long-term enzyme replacement therapy (ERT) with recombinant human arylsulfatase B (rhASB; rhN-acetylgalactosamine 4-sulfatase). Pulmonary function tests prior to and for up to 240 weeks of weekly infusions of rhASB at 1 mg/kg were completed in 56 patients during Phase 1/2, Phase 2, Phase 3 and Phase 3 Extension trials of rhASB and the Survey Study. Forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1) and, in a subset of patients, maximum voluntary ventilation (MVV), were analyzed as absolute volume in liters. FEV1 and FVC showed little change from baseline during the first 24 weeks of ERT, but after 96 weeks, these parameters increased over baseline by 11% and 17%, respectively. This positive trend compared with baseline continued beyond 96 weeks of treatment. Improvements from baseline in pulmonary function occurred along with gains in height in the younger group (5.5% change) and in the older patient group (2.4% change) at 96 weeks. Changes in MVV occurred earlier within 24 weeks of treatment to approximately 15% over baseline. Model results based on data from all trials showed significant improvements in the rate of change in pulmonary function during 96 weeks on ERT, whereas little or no improvement was observed for the same time period prior to ERT. Thus, analysis of mean percent change data and longitudinal modeling both indicate that long-term ERT resulted in improvement in pulmonary function in MPS VI patients.

T helper cells ,CYTOTOXIC T cells ,LYSOSOMAL storage diseases ,LEUCOCYTES ,DERMATAN sulfate - Abstract
Mucopolysaccharidoses (MPSs) are rare inherited lysosomal storage diseases (LSDs) caused by deficient activity in one of the enzymes responsible for glycosaminoglycans lysosomal degradation. MPS II is caused by pathogenic mutations in the IDS gene, leading to deficient activity of the enzyme iduronate-2-sulfatase, which causes dermatan and heparan sulfate storage in the lysosomes. In MPS VI, there is dermatan sulfate lysosomal accumulation due to pathogenic mutations in the ARSB gene, leading to arylsulfatase B deficiency. Alterations in the immune system of MPS mouse models have already been described, but data concerning MPSs patients is still scarce. Herein, we study different leukocyte populations in MPS II and VI disease patients. MPS VI, but not MPS II patients, have a decrease percentage of natural killer (NK) cells and monocytes when compared with controls. No alterations were identified in the percentage of T, invariant NKT, and B cells in both groups of MPS disease patients. However, we discovered alterations in the naïve versus memory status of both helper and cytotoxic T cells in MPS VI disease patients compared to control group. Indeed, MPS VI disease patients have a higher frequency of naïve T cells and, consequently, lower memory T cell frequency than control subjects. Altogether, these results reveal MPS VI disease-specific alterations in some leukocyte populations, suggesting that the type of substrate accumulated and/or enzyme deficiency in the lysosome may have a particular effect on the normal cellular composition of the immune system.

Doenças Lisossomais de sobrecarga ,Lysosomal Storage Disorders ,Genética Humana ,Doenças Genéticas - Abstract
Lysosomal storage disorders (LSD) are a group of rare diseases caused mutations in genes that encode lysosomal enzymes, membrane proteins or transporters. This leads to an accumulation of undegraded substrates, which ultimately causes a broad range of highly debilitating clinical symptoms affecting multiple organs/systems, including the central nervous system. Yet, most therapies for LSD are limited to treating non-neurological signs. Thus, there is an urgent need for the development of new ones that can tackle the neuronal pathogenesis. Fortunately, the portfolio of innovative therapeutic approaches under development has been growing tremendously and the need for proper models grows alongside. To address this concern, we propose the development and characterization of innovative patient-derived cell models for early onset neurodegenerative LSD using dental pulp stem cells (DPSC) from deciduous “baby” teeth. DPSCs hold potential to give rise to a variety of cells including functionally active neurons. Nevertheless, to the best of our knowledge, this sort of technology hasn’t yet been applied to samples obtained from LSD patients. This will be a total innovation in the field and we believe it holds potential to set a new trend for investigating LSD as it relies on a non-invasive, cost effective approach that can be set as a routine in any lab with standard cell culture conditions. Here we present an update on this project, summarizing its rationale and current results, while giving an overview of the whole protocol and discussing its potential applications. Briefly, over the last months, we have successfully implemented the protocol for the establishment of control DPSC cultures in our lab and are currently working on the differentiation protocol, which will allow the formation of mixed neuronal and glial cultures. We are also actively working with patients’ associations and a team of expert pediatricians from the major reference centers for treatment of LSD to identify potential volunteers for baby teeth collection, having already approached several families, who are now actively involved in the project and willing to send us deciduous baby teeth, as soon as they fall.

Anabela Oliveira, Presidente CCTDLS Relatório anual ‘Tratamento de doenças lisossomais de sobrecarga’, referente às atividades desenvolvidas pela respetiva Comissão Coordenadora em 2020. As Doenças Lisossomais de Sobrecarga (DLS) constituem um grupo de patologias raras, progressivas, com elevada morbilidade, que engloba, atualmente, mais de 60 patologias, cuja apresentação clínica é extremamente variável, podendo ir desde doença neurológica grave até a casos menos graves. Em Portugal, a prevalência deste tipo de patologias em recém-nascidos é de 25 por cada 100.000 nados-vivos. Nos últimos anos, várias terapêuticas de substituição enzimática e de redução do substrato têm sido desenvolvidas possibilitando o tratamento dos doentes com algumas destas patologias, nomeadamente, a Doença de Gaucher, a Doença de Fabry, a Doença de Pompe, as Mucopolissacaridoses tipo I, II, IVA e VI, a Deficiência de lipase ácida lisossomal e a Doença de Niemann-Pick tipo C. Pelo Despacho n.º 2545/2013, foi criada a Comissão Coordenadora do Tratamento das Doenças Lisossomais de Sobrecarga (CCTDLS), que funciona junto do INSA, sendo atualmente constituída por profissionais designados pelo INSA, pelos Centros de Referência nesta área, pela Administração Central do Sistema de Saúde, pela Direção-Geral da Saúde e pela Autoridade Nacional do Medicamento e Produtos de Saúde (Infarmed).

Purpose. To describe retinal findings in a patient with mucopolysaccharidosis type I (MPS I) that underwent an early treatment with hematopoietic stem cell transplantation (HSCT) and enzyme replacement therapy (ERT). Case Report. We describe a case of a 12-year-old female with a biochemical and genetic diagnosis of MPS I. She underwent HSCT and ERT on the first year of life. The visual acuity was 5/10 in both eyes and she had bilateral grade 2 corneal haze. Spectral domain optical coherence tomography (SD-OCT) revealed thickening of the external limiting membrane (ELM) at the fovea. In the parafoveal and perifoveal regions, SD-OCT displayed a loss of the interdigitation, ellipsoid, and myoid zones and of the ELM accompanied by progressive thinning of the outer nuclear layer. Fundus infrared imaging revealed a hyperreflective ring centred on the fovea and hyporeflective areas in temporal parafoveal regions in both eyes. En face OCT imaging revealed two hyperreflective rings on the outer retinal level. Conclusion. This patient developed macular changes with foveal deposition of hyperreflective material and parafoveal thinning, despite early systemic treatment. Systemic therapies can provide an increase in life expectancy and stabilize visual acuity and corneal clouding, although their effect on retinal degeneration is unknown.

- Abstract
Recently, a disorder caused by the heterozygous de novo c.1267C>T (p.R423*) substitution in has been described. This causes mislocalization of the glucose-6-phosphate transporter to the Golgi leading to a congenital disorder of glycosylation type II (SLC37A4-CDG). Only one patient has been reported showing liver disease that improved with age and mild dysmorphism. Here we report the second patient with a type II CDG caused by the same heterozygous de novo c.1267C>T (p.R423*) mutation thereby confirming the pathogenicity of this variant and expanding the clinical picture with type 1 diabetes, severe scoliosis, and membranoproliferative glomerulonephritis. Additional clinical and biochemical data provide further insight into the mechanism and prognosis of SLC37A4-CDG.

Public involvement in the governance of epidemiological and public health studies can foster needs-driven research, enhance participants' recruitment, reduce attrition and improve the quality of and ethics in research and surveillance. However, it can also reinforce health inequalities if it fails to ensure public representation across socioeconomic gradients. This study aimed to assess patients' and carers' preferences for involvement in collective health data governance, and its associated factors, to strengthen the evidence base for policy development.

- Abstract
Mucopolysaccharidosis (MPS) disorders are a group of rare, progressive lysosomal storage diseases characterized by the accumulation of glycosaminoglycans (GAGs) and classified according to the deficient enzyme. Enzyme replacement therapy (ERT) of MPS VI has limited effects on ophthalmic, cardiovascular, and skeletal systems. Odiparcil is an orally available small molecule that results in the synthesis of odiparcil‐linked GAGs facilitating their excretion and reducing cellular and tissue GAG accumulation. Improve MPS treatment was a Phase 2a study of the safety, pharmacokinetics/pharmacodynamics, and efficacy of two doses of odiparcil in patients with MPS VI. The core study was a 26‐week, randomized, double‐blind, placebo‐controlled trial in patients receiving ERT and an open‐label, noncomparative, single‐dose cohort not receiving ERT. Patients aged ≥ 16 years receiving ERT were randomized to odiparcil 250 or 500 mg twice daily or placebo. Patients without ERT received odiparcil 500 mg twice daily. Of 20 patients enrolled, 13 (65.0%) completed the study. Odiparcil increased total urine GAGs (uGAGs), chondroitin sulfate, and dermatan sulfate concentrations. A linear increase in uGAG levels and odiparcil exposure occurred with increased odiparcil dose. Odiparcil demonstrated a good safety and tolerability profile. Individual analyses found more improvements in pain, corneal clouding, cardiac, vascular, and respiratory functions in the odiparcil groups vs placebo. This study confirmed the mechanism of action and established the safety of odiparcil with clinical beneficial effects after only a short treatment duration in an advanced stage of disease. Further assessment of odiparcil in younger patients is needed. [ABSTRACT FROM AUTHOR]

Lysosomal Storage Diseases ,Functional studies ,Genetic Diseases ,Niemann-Pick type C ,Doenças Genéticas - Abstract
Niemann-Pick type C (NP-C) is a neurodegenerative Inherited Metabolic Disease with a heterogeneous clinical presentation, due to mutations in either the NPC1 or NPC2 genes. We studied patients with clinical diagnosis of NP-C but presenting inconclusive results regarding biomarkers testing and molecular analysis. Using NGS- targeted DNA sequencing we have identified some novel putative mutations and subsequent cDNA analysis allowed us to stablish the functional effect of a silent mutation (previously reported as a polymorphism) in the NPC1 splicing process. We demonstrated that this mutation leads to exon skipping, frameshift and premature stop codon and identified it in two NP-C patients from two unrelated Portuguese families. This mutation most likelly leads to a very unstable transcript that was overlooked. Also, to better characterize the pathomechanisms related to specific disease-causing mutations in NP-C patients, we analysed gene expression profiles in cultured skin fibroblasts and compared them to control individuals using Massively Parallel RNA Single-Cell Sequencing (MARS-Seq). The most prominent hits from this transcriptomics analysis were validated by qRT-PCR. The MARS-Seq analysis showed that a number of genes were upregulated and a significant number of the highly enriched genes are related to the unfold protein response (UPR) and Endoplasmic Reticulum (ER) stress, in a specific patient, which deserves further studies. ER stress is a hallmark of many neurodegenerative diseases, including LSD and can be due to misfolded/unfolded proteins as result of a specific missense mutation. Our preliminary results suggest that UPR activation is variable among NP-C patients, and this is likely to depend on the mutation type. Several other factors may contribute to this though, which could explain the heterogeneous presentation of this pathology. Additionally, we have investigated the same patients studied in MARS-Seq at the protein and celular levels. Interestingly, and according to recently published work, we observed that, for the analyzed mutations a significant part of the mutated NPC1 protein was retained/ delayed in the ER. N/A

NP-C is a neurodegenerative Inherited Metabolic Disease with a heterogeneous clinical presentation, and due to mutations in either the NPC1 or NPC2 genes.We have studied a patient with clinical diagnosis of NP-C but presenting inconclusive results regarding molecular analysis.To better characterize this patient, we have performed NGS-based technologies (targeted DNA sequencing and single cell-RNA sequencing).For the molecular diagnosis we used a NGS gene panel followed by the analysis of cDNA.Latter, we used massively parallel single cell RNA-seq (MARS-Seq) to address gene profiling changes and characterize the pathomechanisms related to specific disease-causing mutations. Using our targeted NGS panel we identified two novel mutations in NPC1 gene.Next, through cDNA analysis of one of the patient parents we were able to understand the impact of the silent mutation.This mutation leads to exon skipping giving origin to an out-of-frame transcript and eliciting the nonsense-mediated decay pathway.Thus, we were not able to easily detect the mutant transcript which turned the molecular diagnosis more challenging. Apparently the presence of the other mutation (a missense mutation) impairs the NPC protein folding leading to its ER retention.The MARS-Seq analysis of this patient showed that a number of upregulated genes are related to the unfold protein response (UPR) and ER stress, which deserves further studies.
