Neurological Phenotypes of IRF2BPL Gene Variants: A Report of Four Novel Variants.

IRF2BPL gene variants have recently been associated to developmental disability and epilepsy in children and movement disorders in adults. So far, only few cases have been reported; here we present four novel cases identified by exome sequencing, while investigating developmental delay, adult-onset cerebellar ataxia or regression.

Spinal cord occupation ratio (SCOR) and its application in the diagnosis of cervical spinal cord compression in Mucopolysaccharidoses

Abstract Introduction Mucopolysaccharidoses (MPS) can lead to cervical spinal cord compression (SCC). Diagnostic scores for SCC in MPS use the obliteration of the passage of cerebrospinal fluid in the anterior and posterior spinal cord in the sagittal section of magnetic resonance imaging (MRI). The spinal cord occupation ratio (SCOR) published, by Nouri et al (2018), establishes the spinal cord filling index for the spinal cord, identifying disproportionate spinal cord occupation in the canal. When evaluating congenital canal stenosis, the risk of spinal cord injury has been considered increased when the SCOR is ≥70% in the median sagittal plane or ≥ 80% in the axial plane. Although these values ​​have not been validated for MPS populations, they could be useful. Objective To verify the SCOR in MPS patients with diagnosis of cervical SCC comparing the SCOR with other markers proposed in the existing MPS SCC scores, such as the extent of gliosis, clinical impact and the SCC assessment as represented by the obliteration of CSF flow. Methods We reviewed imaging tests of the cervical spine from MPS patients with previously confirmed SCC, using the SCOR measure in the median sagittal plane, evaluation of the presence and extent of spinal gliosis on MRI, evaluation of the clinical impact using a clinical score and evaluation of the images for the obliteration of cerebral spinal fluid (CSF) flow. Results Thirty-one MRI of 24 different patients were included. The average SCOR was 87.1%. This was lower (81.6%) in patients without gliosis, when compared to those with focal (90.5%) and extensive (97%) gliosis. The only patient with gliosis associated with a lacunar lesion, resulting from an acute compressive injury, had a 68% SCOR, due to the atrophic spinal cord injury. As expected, SCOR was higher in patients with total or partial CSF obliteration, but one among the 3 patients without CSF flow obliteration, with a 76% SCOR, had already developed focal gliosis and mild clinical abnormalities. Patients with more extensive gliosis had higher clinical scores. Four patients had more than one imaging scan evaluated. SCOR upward trend showed an annual average increase of 3.8%. Discussion & Conclusions The use of SCOR allows the diagnosis of cervical spinal canal stenosis in an objective way. It is possible that the cut-off values used by Nouri et al in patients with congenital stenosis could be useful to diagnose cervical stenosis in MPS patients, preceding the finding of CSF flow obstruction, presence of gliosis or clinical abnormalities. Furthermore, the use of SCOR may assist in the longitudinal evaluation of disease progression. Better follow-up and timely diagnosis allows for scheduling of surgery at the best clinical moment, minimizing complications.

Síndrome de Cornelia de Lange: análise de uma série de 33 pacientes em um centro de referência / Cornelia de Lange syndrome: analysis of a series of 33 patients in an excellence center

Introdução: A Síndrome de Cornelia de Lange (CdLS) (OMIM: 122470) é uma doença genética rara com quadro clínico e fenótipo variáveis, compreendendo um grupo de doenças denominado coesinopatias. Entre suas principais características: deficiência intelectual (DI), baixa estatura, doença do refluxo gastroesofágico (DRGE), hipertricose, dismorfismos faciais e anomalias em membros superiores. O diagnóstico pode ser dificultado nos quadros atenuados. O objetivo do estudo foi determinar os principais achados clínicos e moleculares em uma série de pacientes com o diagnóstico clínico de CdLS.Métodos: Foram avaliados 33 pacientes com diagnóstico clínico e/ou molecular de CdLS (18 sexo feminino e 15 masculino) com idades entre 1 mês e 43 anos. Aplicou-se um escore clínico visando a categorização dos pacientes baseado em Kline et al. (2018). Esta ferramenta utiliza sinais clínicos para determinar as formas clássicas (n: 23), não clássicas (n: 6) e os casos que, apesar de não se enquadrarem nestas categoriais, também deveriam ser testados molecularmente para a síndrome (n: 4).Resultados: Atraso do desenvolvimento/DI, distúrbios de comportamento, déficit de crescimento e DRGE foram as comorbidades mais prevalentes. Entre as dismorfias: sinofris, micrognatia, narinas antevertidas e comissura labial desviada para baixo. Os achados moleculares nos pacientes submetidos ao sequenciamento completo do exoma revelaram 6 variantes em NIPBL (46%), 2 variantes em SMC1A (15%), 1 variante em SMC3, 1 variante em HDAC8, 1 variante em AHDC1 e 2 resultados negativos.Conclusões: Os dados obtidos revelaram uma grande heterogeneidade de apresentação da síndrome. A utilização de escores clínicos podem auxiliar no diagnóstico de CdLS.

Introduction: Cornelia de Lange syndrome (CdLS) (OMIM: 122470) is a rare genetic disease with variable clinical presentation and phenotype, part of a group of disorders termed cohesinopathies. Intellectual disability, growth retardation, gastroesophageal reflux disease, hypertrichosis, facial dysmorphisms, and anomalies of the upper limbs are the most common clinical characteristics. Diagnosis may be difficult, especially in attenuated presentations. The aim of this study was to determine the main clinical and molecular findings in a series of patients with clinical diagnosis of CdLS.Methods: Thirty-three patients with typical clinical and/or molecular diagnosis of CdLS (18 female and 15 male) aged between 1 month and 43 years were evaluated. A clinical score was applied to categorize patients. This tool uses clinical signs to determine the classic (n: 23) and nonclassic (n: 6) forms, in addition to a category to suggest which cases should be molecularly tested for the syndrome (n: 4).Results: Developmental delay/intellectual disability, behavioral disorders, growth retardation, and gastroesophageal reflux disease were the most prevalent comorbidities. Dysmorphic features included synophrys micrognathia, anteverted nostrils, and labial commissure turning downwards. Molecular findings in those who underwent whole exome sequencing revealed 6 variants in NIPBL (46%), 2 variants in SMC1A (15%), 1 variant in SMC3, 1 variant in HDAC8, 1 variant in AHDC1, and 2 negative results.Conclusions: The data revealed a great heterogeneity in the presentation of the syndrome. The use of clinical scores can help in the diagnosis of CdLS.

Genotype-phenotype studies in a large cohort of Brazilian patients with Hunter syndrome.

Mucopolysaccharidosis type II (MPS II) is an X-linked inherited disease caused by pathogenic variants in the IDS gene, leading to deficiency of the lysosomal enzyme iduronate-2-sulfatase and consequent widespread storage of glycosaminoglycans, leading to several clinical consequences, with progressive manifestations which most times includes cognitive decline. MPS II has wide allelic and clinical heterogeneity and a complex genotype-phenotype correlation. We evaluated data from 501 Brazilian patients diagnosed with MPS II from 1982 to 2020. We genotyped 280 of these patients (55.9%), which were assigned to 206 different families. Point mutations were present in 70% of our patients, being missense variants the most frequent. We correlated the IDS pathogenic variants identified with the phenotype (neuronophatic or non-neuronopathic). Except for two half-brothers, there was no discordance in the genotype-phenotype correlation among family members, nor among MPS II patients from different families with the same single base-pair substitution variant. Mothers were carriers in 82.0% of the cases. This comprehensive study of the molecular profile of the MPS II cases in Brazil sheds light on the genotype-phenotype correlation and helps the better understanding of the disease and the prediction of its clinical course, enabling the provision of a more refined genetic counseling to the affected families.

Mucopolysaccharidosis VII in Brazil: natural history and clinical findings.

BACKGROUND: Mucopolysaccharidosis type VII (MPS VII), also known as Sly syndrome, caused by deficiency of the lysosomal enzyme ß-glucuronidase, is an ultra-rare disorder with scarce epidemiological data and few publications about natural history and clinical spectrum. METHODS: We conducted a case series report which included retrospective data from all MPS VII patients diagnosed through the "MPS Brazil Network" who were known to be alive in 2020 in Brazil (N = 13). Clinical data were obtained from a review of the medical records and descriptive statistics and variables were summarized using counts and percentages of the total population. RESULTS: The majority of the patients were from the Northeast region of Brazil. Among the signs and symptoms that raised the clinical suspicion of MPS, coarse face was the most frequent; 58% of the patients had a history of non-immune hydrops fetalis. All the subjects presented short neck and trunk. The majority presented typical phenotypical signs of MPS disorders. They all presented neurodevelopmental delay and cognitive impairment. About half of this cohort had knees deformities. Dysostosis multiplex was identified in almost all patients and cardiomyopathy was less frequent than observed in other types of MPSs. The mean age at diagnosis was 5 years, ranging from 1 to 14 years. Almost all patients (12/13) were homozygous for the c.526C>T (p.Leu176Phe) mutation. A novel variant of the GUSB gene was found, the c.875T>C (p.Leu292Pro), in a compound heterozygous with the c.526C>T (p.Leu176Phe) variant. CONCLUSIONS: This case series is the biggest data collection of MPS VII patients alive in Latin America. The overall clinical picture of the MPS VII patients is very similar to other MPS disorders, including a spectrum of severity and delayed diagnosis.

Enzyme replacement therapy interruption in mucopolysaccharidosis type IVA patients and its impact in different clinical outcomes.

Mucopolysaccharidosis type IVA (MPS IVA) is an autosomal recessive lysosomal storage disorder caused by mutations in the GALNS gene, which leads to deficient activity of N-acetylglucosamine-6-sulfate sulfatase. MPS IVA patients usually present skeletal dysplasia, coarse features, short stature, airway obstruction, cervical spinal cord compression, dental abnormalities, and cardiac valvular alterations. Enzyme replacement therapy (ERT) with elosulfase alfa is the only disease-specific treatment available for MPS IVA patients and has been shown to improve important clinical and biochemical parameters; however, little is known about the effects of ERT interruption on these patients. In this article, we report the impact of different periods of treatment interruption on clinical outcomes of 18 MPS IVA patients. All MPS IVA patients included in this case series were treated and followed up in Latin American centers and had been receiving elosulfase alfa intravenously for at least 8 months before ERT was interrupted. Different clinical parameters and assessments were evaluated at variable timepoints following therapy interruption. Altogether, our report indicates that some beneficial ERT effects in MPS IVA patients may last after different periods of treatment interruption, as cardiac and respiratory function improvements. However, worsening of important disease parameters after ERT interruption, such as the increase in uGAGs, pain, joint and skeletal aspects, and surgery indications suggests that treatment discontinuation should be avoided in order to maintain the disease as stable as possible, aiming to optimize these patients' life expectancy and quality of life.

SARS-CoV-2 pandemic in the Brazilian community of rare diseases: A patient reported survey.

The COVID-19 pandemic has led to a reorganization of health systems to prioritize the fight against the virus. The adoption of social distancing interfered with the flow of existing policies, and may thus negatively affect the most vulnerable groups, such as the rare disease community. Aimming at characterizing the perception of the impact of COVID-19 on the health care of the Brazilian rare disease community, an online questionnaire addressed to patients with rare diseases and their caregivers was disseminated in the Brazilian territory between June 1st to July 5th, 2020. The questions dealt with the sanitary measures adopted; access to medical services; and mental suffering during the pandemic. The survey was answered by 1,466 participants (<18 yo = 53.3%) representing 192 rare diseases. Regarding physical distancing, 1,372 (93.6%) participants did not leave their residence, or did so only when essential; 1,321 (90.1%) always wore masks when leaving home. 1,042 (71.1%) and 995 (67.9%) participants, respectively, referred medical genetics appointments and rehabilitation therapies were postponed/canceled. Telemedicine was experienced by 1,026 (70%), and 68.3% agreed this is a good strategy for health care. Patients with Inborn Errors of Metabolism (IEM, n = 624, 42.5%) appear to have more access to information and ability to overcome difficulties, and feel less threatened, lonely and depressed than the non-IEM group (p < .05). There was an increment of the rare disease patients' vulnerability in the pandemic scenario. The cooperation of patients/caregivers along with adaptation of the health system is crucial and may be so even post-pandemic.

Clinical Characterization of Mucolipidoses II and III: A Multicenter Study.

Mucolipidoses (MLs) II and III are rare lysosomal diseases caused by deficiency of GlcNAc-1-phosphotransferase, and clinical manifestations are multisystemic. Clinical and demographic data from 1983 to 2013 were obtained retrospectively. Twenty-seven patients were included (ML II = 15, ML III α/beta = 9, ML III gamma = 3). The median age at diagnosis was 2.7 years. The predominant clinical presentations were skeletal symptoms. The ML II patients showed physical and cognitive impairment, while the ML III α/beta patients have more somatic abnormalities and usually were delayed in early development as compared with ML III gamma patients. This is the most comprehensive study exploring characteristics of Brazilian patients with MLs II and III.

Otolaryngologists and the Early Diagnosis of Mucopolysaccharidoses: A Cross-Sectional Study.

Mucopolysaccharidoses (MPS) are a group of inborn errors of metabolism with an aggressive and usually fatal course. Therefore, early treatment is essential because the involvement of head and neck structures is almost always present in MPS. Our study aimed to retrospectively assess-via a chart review and a survey of caregivers-the history of ear, nose and throat (ENT) symptoms, the number of otolaryngology visits prior to diagnosis, and whether otolaryngologists diagnosed the disease in a cohort of MPS patients followed at an academic medical center. Twenty-three patients were evaluated. Age at diagnosis ranged from 0.2 to 33.0 years (median, 3.2 years). Prior to being diagnosed with MPS, 20/23 (87%) patients presented with at least one episode of otalgia, airway disorder, sleep disturbance, speech delay or suspected hearing loss. One patient had an adenotonsillectomy with paracentesis of tympanic membranes. Ten of the 23 patients (43%) were seen by an otolaryngologist before the diagnosis of MPS, none of which had the disease suspected during these visits. Notwithstanding limitations, our results suggest that increased awareness of MPS among otolaryngologists may allow for earlier diagnosis and better management of these patients.

Rare diseases and the associative dialogue: resignifications for moral experiences. / Adoecimentos raros e o diálogo associativo: ressignificações para experiências morais.

This paper aims to discuss the experience of relatives of children and adolescents with rare diseases as a moral experience. Moral experience is characterized by suffering that is socially interpreted as a catastrophic event, mobilizing resources for signification and meaning that allow the reconstruction of identity, the appreciation of itineraries from a rare diagnosis, as well as the search for peers. Thus, the construction of relationships of recognition, alterity, and belonging is fundamental. From a symbolic interactionist perspective, the results show two significant cores: (1) shock as a surprise in the face of an unexpected diagnosis, leading to the search for peers and promotion of social recognition; (2) the cost involved with the course of a rare disease that implies a care work and the acquisition of associative capital as a possibility of strengthening and building the social capital of health care.

Neste artigo, buscamos discutir a experiência de familiares de crianças e adolescentes com doenças raras como uma experiência moral. A experiência moral se caracteriza pelo sofrimento que é lido, coletivamente, como acontecimento catastrófico, mobilizando recursos para significação e sentido que possibilitem reconstruções identitárias, valoração de novas trajetórias a partir de um diagnóstico raro, assim como a busca de pares. Nesse sentido, é fundamental a construção de relações de reconhecimento, alteridade e pertencimento. A partir de uma perspectiva interacionista simbólica, os resultados mostram dois núcleos: (1) o susto como surpresa diante do diagnóstico inesperado, levando a busca de pares e promoção do reconhecimento social; (2) o custo envolvido com a trajetória de uma doença rara que implica um trabalho de care e a aquisição de capital associativo como possibilidade de fortalecimento e construção de capital social de cuidado à saúde.

[Complex care, high cost, and loss of income: frequent issues for families of children and adolescents with rare health conditions]. / Cuidado complexo, custo elevado e perda de renda: o que não é raro para as famílias de crianças e adolescentes com condições de saúde raras.

Estimates point to more than seven thousand rare diseases already identified, representing 6 to 10% of all diseases. In Brazil, a rare disease is defined as one that affects up to 65 persons per 100,000. The quantification of costs for the families of patients with such conditions and their impact on income provides information capable of supporting public policies for these youngsters. The study aimed to estimate the cost and loss of earnings, viewed from the perspective of families of children and adolescents with cystic fibrosis, mucopolysaccharidosis, and osteogenesis imperfecta. The study included 99 families of patients treated at a national referral hospital for rare diseases in Rio de Janeiro, based on the principal caregiver's report. The descriptive data analysis showed that the median direct nonmedical cost for families was BRL 2,156.56 (USD 570) for cystic fibrosis, BRL 1,060.00 (USD 280) for mucopolysaccharidosis, and BRL 1,908.00 (USD 505) for osteogenesis imperfecta. Loss of earnings exceeded 100% for all three diseases. A total of 54% of families fail to receive any social benefits. The estimate of coping costs indicated that 69% of the families had incurred loans and that 22.5% had sold household assets to cope with the treatment costs. Catastrophic expenditures were observed in families dealing with the three diseases. The results unveil costs that are rarely estimated, and not only in the field of rare diseases. The findings point to a major burden on the families' income. It is important to incorporate such studies in the discussion of financing, the incorporation of new technologies, and the supply of health services.

Recommendations for Assessment and Management of Health-Related Quality of Life in Patients with Mucopolysaccharidoses in Latin America

Abstract Mucopolysaccharidoses (MPS) constitute a heterogeneous group of rare genetic disorders caused by enzymatic deficiencies that lead to the accumulation of glycosaminoglycans (GAGs). Clinical observations suggest a health-related impairment in quality of life in patients with MPS. Professionals with extensive experience in the care of patients with inborn errors of metabolism, such as MPS, held a meeting in April 2017 to discuss and propose recommendations for the evaluation and management of quality of life in MPS patients in Latin America. In the light of this scenario, the present work summarizes the content of the discussions and presents the recommendations produced at the meeting. The panel had suggested the use of the following tools for the assessment of health-related quality of life (HRQoL): Children's Health Assessment Questionnaire (CHAQ) for children and patients unable to express their feelings, Health Assessments Questionnaire (HAQ) and EuroQol 5 Domains (EQ-5D) scales for adult patients. Based on the scores verified in these scales, the panel proposes interventions that aim reducing the impairment of the quality of life in patients with MPS disorders.

[Treatment networks and associations of patients with rare diseases]. / Redes de tratamento e as associações de pacientes com doenças raras.

Patients' associations are an example of biosocial groups, since their formation is motivated by common biological characteristics, such as rare diseases, and they are sometimes included in social movements in health. Even though the National Policy on Comprehensive Care for Persons with Rare Diseases was enacted in 2014, patients still struggle to ensure access to and treatment by the Unified Health System. The way in which associations of patients with rare diseases gain access to treatment via social networks, is investigated. This research is part of a study about the use of social media by associations of patients with rare diseases, which employs netnography - ethnography applied to the web - as the data-gathering method. Data sources were pages of the associations on Facebook in Brazil. It was seen that the activities of the associations are multi-faceted, ranging from patient and family guidance about treatment and quality of life, to active participation in the elaboration and implementation of public policies. The discourses suggest that the focus of patients' associations is, in the majority of cases, the access to drugs rather than the effective enactment of the national policy geared towards rare diseases.

As associações de pacientes são um exemplo de grupos biossociais, já que sua constituição é motivada por questões biológicas comuns, tais como as doenças raras, e estão, por vezes, inscritas no movimento social em saúde. Apesar da Política Nacional de Atenção Integral às Pessoas com Doenças Raras ter sido promulgada em 2014, os pacientes ainda têm dificuldade em garantir acesso a tratamento pelo Sistema Único de Saúde. Investigamos como as associações de pacientes com doenças raras tecem, através das redes sociais virtuais, o acesso a tratamento. Esta pesquisa é parte de um estudo sobre o uso das mídias sociais pelas associações de pacientes com doenças raras, e emprega como método a netnografia. As fontes da pesquisa foram páginas de associações de pacientes com doenças raras no Brasil presentes no Facebook. Observamos que a atuação das associações de pacientes é plural, indo desde a orientação de pacientes e familiares sobre questões relacionadas a tratamento e qualidade de vida, até a participação ativa na elaboração e implementação de políticas públicas. Os discursos sugerem que o foco destas associações é, na maior parte dos casos, o acesso a medicamentos, em detrimento da implantação efetiva da Política Nacional de Atenção Integral às Pessoas com Doenças Raras.
