TPP2 mutation associated with sterile brain inflammation mimicking MS

2018

ObjectiveTo ascertain the genetic cause of a consanguineous family from Syria suffering from a sterile brain inflammation mimicking a mild nonprogressive form of MS.MethodsWe used homozygosity mapping and next-generation sequencing to detect the disease-causing gene in the affected siblings. In addition, we performed RNA and protein expression studies, enzymatic activity assays, immunohistochemistry, and targeted sequencing of further MS cases from Austria, Germany, Canada and Jordan.ResultsIn this study, we describe the identification of a homozygous missense mutation (c.82T>G, p.Cys28Gly) in the tripeptidyl peptidase II (TPP2) gene in all 3 affected siblings of the family. Sequencing o…

TNFA promoter polymorphisms and narcolepsy

2003

Narcolepsy is a debilitating sleep disorder that affects up to 0.05% of individuals in Caucasian populations. It is highly associated with the HLA-DR2 group antigen or the HLA-DRB1*1501-DQB1*0602 haplotype, respectively. However, the HLA association by itself cannot sufficiently explain the increased risk to family members, as HLA-DR2 is quite common in the general population and most people harboring the respective genotype do not develop any symptoms of narcolepsy. Situated in the HLA class II region, the TNFA gene is translated into the pro-inflammatory cytokine TNF-alpha. TNFA promoter polymorphisms have been linked to several inflammatory and autoimmune diseases. We analyzed three SNP …

Multiple sclerosis severity score: Using disability and disease duration to rate disease severity

2005

Background: There is no consensus method for determining progression of disability in patients with multiple sclerosis (MS) when each patient has had only a single assessment in the course of the disease. Methods: Using data from two large longitudinal databases, the authors tested whether cross-sectional disability assessments are representative of disease severity as a whole. An algorithm, the Multiple Sclerosis Severity Score (MSSS), which relates scores on the Expanded Disability Status Scale (EDSS) to the distribution of disability in patients with comparable disease durations, was devised and then applied to a collection of 9,892 patients from 11 countries to create the Global MSSS. I…

Increased Frequency of Migraine in Narcoleptic Patients: A Confirmatory Study

2003

Previously we have reported an increased prevalence of migraine in narcoleptic patients. Because of the theoretical and clinical implications of this finding we recruited an independent new study sample of 100 patients with proven narcolepsy and conducted a structured 26-item interview based on the international diagnostic criteria for headache disorders, the Kiel Headache Questionnaire. Narcolepsy symptoms were measured by means of the Stanford Centre for Narcolepsy Sleep Inventory. Migraine prevalence was twofold to fourfold increased in the narcoleptic patients and amounted to 44.4% in women and 28.3% in men. The onset of narcolepsy symptoms was 12.3 ± 11.4 years before the onset of mig…

Transcriptional profiles from patients with dystrophinopathies and limb girdle muscular dystrophies as determined by qRT-PCR.

2003

Mutations in genes coding for the dystrophin-glycoprotein complex (DGC) cause inherited muscular dystrophies (MD), including Morbus Duchenne (DMD) and M. Becker (BMB) as well as limb-girdle muscular dystrophies (LGMD). New insights into the pathophysiology of the dystrophic muscle, the identification of compensatory mechanisms and additional proteins interacting with dystrophin are essential for developing new treatments. In order to define molecular mechanisms induced by lack of dystrophin and the subsequent counter-regulatory transcriptional response of degenerating muscle fibres, we have investigated the mRNA expression of 19 functionally linked genes in biopsies of patients with MD by m…
