The aim of the study was to evaluate a quantitative PCR (qPCR) protocol established by Boehm et al. (2004) in the clinical routine of subtelomeric testing. Results: 296 patients with MR and a normal karyotype (500-550 bands) were screened for subtelomeric imbalances by using qPCR combined with SYBR green detection. In total, 17 patients (5.8%) with 20 subtelomeric imbalances were identified. Six of the aberrations (2%) were classified as causative for the symptoms, because they occurred either de novo in the patients (5 cases) or the aberration were be detected in the patient and an equally affected parent (1 case). The extent of the deletions ranged from 1.8 to approximately 10 Mb, duplications were 1.8 to approximately 5 Mb in size. In 6 patients, the copy number variations (CNVs) were rated as benign polymorphisms, and the clinical relevance of these CNVs remains unclear in 5 patients (1.7%). Therefore, the overall frequency of clinically relevant imbalances ranges between 2% and 3.7% in our cohort."],["dc.identifier.doi","10.1186/1755-8166-2-10"],["dc.identifier.isi","000208460900009"],["dc.identifier.pmid","19284615"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/5765"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/17987"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Biomed Central Ltd"],["dc.relation.issn","1755-8166"],["dc.rights","CC BY 2.0"],["dc.rights.uri","https://creativecommons.org/licenses/by/2.0"],["dc.title","Identification of subtelomeric genomic imbalances and breakpoint mapping with quantitative PCR in 296 individuals with congenital defects and/or mental retardation"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]Details DOI PMID PMC WOS2021Journal Article Research Paper [["dc.bibliographiccitation.artnumber","64"],["dc.bibliographiccitation.issue","1"],["dc.bibliographiccitation.journal","Orphanet Journal of Rare Diseases"],["dc.bibliographiccitation.volume","16"],["dc.contributor.author","Reinert, Marie-Christine"],["dc.contributor.author","Pacheu-Grau, David"],["dc.contributor.author","Catarino, Claudia B."],["dc.contributor.author","Klopstock, Thomas"],["dc.contributor.author","Ohlenbusch, Andreas"],["dc.contributor.author","Schittkowski, Michael Peter"],["dc.contributor.author","Wilichowski, Ekkehard"],["dc.contributor.author","Rehling, Peter"],["dc.contributor.author","Brockmann, Knut"],["dc.date.accessioned","2021-04-14T08:28:08Z"],["dc.date.available","2021-04-14T08:28:08Z"],["dc.date.issued","2021"],["dc.date.updated","2022-07-29T12:17:42Z"],["dc.description.abstract","Background Leber hereditary optic neuropathy (LHON) is the most common mitochondrial disorder and characterized by acute or subacute painless visual loss. Environmental factors reported to trigger visual loss in LHON mutation carriers include smoking, heavy intake of alcohol, raised intraocular pressure, and some drugs, including several carbonic anhydrase inhibitors. The antiepileptic drug sulthiame (STM) is effective especially in focal seizures, particularly in benign epilepsy of childhood with centrotemporal spikes, and widely used in pediatric epileptology. STM is a sulfonamide derivate and an inhibitor of mammalian carbonic anhydrase isoforms I–XIV. Results We describe two unrelated patients, an 8-year-old girl and an 11-year-old boy, with cryptogenic focal epilepsy, who suffered binocular (subject #1) or monocular (subject #2) visual loss in close temporal connection with starting antiepileptic pharmacotherapy with STM. In both subjects, visual loss was due to LHON. We used real-time respirometry in fibroblasts derived from LHON patients carrying the same mitochondrial mutations as our two subjects to investigate the effect of STM on oxidative phosphorylation. Oxygen consumption rate in fibroblasts from a healthy control was not impaired by STM compared with a vehicle control. In contrast, fibroblasts carrying the m.14484T>C or the m.3460G>A LHON mutation displayed a drastic reduction of the respiration rate when treated with STM compared to vehicle control. Conclusions Our observations point to a causal relationship between STM treatment and onset or worsening of visual failure in two subjects with LHON rather than pure coincidence. We conclude that antiepileptic medication with STM may pose a risk for visual loss in LHON mutation carriers and should be avoided in these patients."],["dc.description.sponsorship","Open-Access-Publikationsfonds 2021"],["dc.identifier.citation","Orphanet Journal of Rare Diseases. 2021 Feb 04;16(1):64"],["dc.identifier.doi","10.1186/s13023-021-01690-y"],["dc.identifier.pmid","33541401"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/17726"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/82509"],["dc.identifier.url","https://mbexc.uni-goettingen.de/literature/publications/219"],["dc.identifier.url","https://sfb1286.uni-goettingen.de/literature/publications/102"],["dc.language.iso","en"],["dc.notes.intern","DOI Import GROB-399"],["dc.notes.intern","Merged from goescholar"],["dc.relation","EXC 2067: Multiscale Bioimaging"],["dc.relation","SFB 1286: Quantitative Synaptologie"],["dc.relation","SFB 1286 | A06: Mitochondrienfunktion und -umsatz in Synapsen"],["dc.relation.eissn","1750-1172"],["dc.relation.workinggroup","RG Rehling (Mitochondrial Protein Biogenesis)"],["dc.rights","CC BY 4.0"],["dc.rights.holder","The Author(s)"],["dc.rights.uri","https://creativecommons.org/licenses/by/4.0"],["dc.subject","Sulthiame"],["dc.subject","Carbonic anhydrase inhibitor"],["dc.subject","Adverse effects"],["dc.subject","Leber hereditary optic neuropathy"],["dc.subject","LHON"],["dc.subject","Oxygen consumption rate"],["dc.title","Sulthiame impairs mitochondrial function in vitro and may trigger onset of visual loss in Leber hereditary optic neuropathy"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.subtype","original_ja"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]Details DOI PMID PMC2020Journal Article Research Paper [["dc.bibliographiccitation.firstpage","341"],["dc.bibliographiccitation.issue","2"],["dc.bibliographiccitation.journal","Genetics in Medicine"],["dc.bibliographiccitation.lastpage","351"],["dc.bibliographiccitation.volume","23"],["dc.contributor.author","Schröder, Simone"],["dc.contributor.author","Li, Yun"],["dc.contributor.author","Yigit, Gökhan"],["dc.contributor.author","Altmüller, Janine"],["dc.contributor.author","Bader, Ingrid"],["dc.contributor.author","Bevot, Andrea"],["dc.contributor.author","Biskup, Saskia"],["dc.contributor.author","Dreha-Kulaczewski, Steffi"],["dc.contributor.author","Christoph Korenke, G."],["dc.contributor.author","Kottke, Raimund"],["dc.contributor.author","Mayr, Johannes A."],["dc.contributor.author","Preisel, Martin"],["dc.contributor.author","Toelle, Sandra P."],["dc.contributor.author","Wente-Schulz, Sarah"],["dc.contributor.author","Wortmann, Saskia B."],["dc.contributor.author","Hahn, Heidi"],["dc.contributor.author","Boltshauser, Eugen"],["dc.contributor.author","Uhmann, Anja"],["dc.contributor.author","Wollnik, Bernd"],["dc.contributor.author","Brockmann, Knut"],["dc.date.accessioned","2021-04-14T08:31:50Z"],["dc.date.available","2021-04-14T08:31:50Z"],["dc.date.issued","2020"],["dc.description.abstract","Purpose\r\n\r\nThis study aimed to delineate the genetic basis of congenital ocular motor apraxia (COMA) in patients not otherwise classifiable.\r\nMethods\r\n\r\nWe compiled clinical and neuroimaging data of individuals from six unrelated families with distinct clinical features of COMA who do not share common diagnostic characteristics of Joubert syndrome or other known genetic conditions associated with COMA.

Almost all cases of AHC are sporadic but AHC concordance in monozygotic twins and dominant transmission in a family with a milder phenotype have been reported. Thus, we aimed to identify de-novo mutations associated with this disease. Methods We recruited patients with clinically characterised AHC from paediatric neurology departments in Germany and with the aid of a parental support group between Sept, 2004, and May 18, 2012. We used whole-exome sequencing of three proband-parent trios to identify a disease-associated gene and then tested whether mutations in the gene were also present in the remaining patients and their healthy parents. We analysed genotypes and characterised their associations with the phenotypic spectrum of the disease. Findings We studied 15 female and nine male patients with AHC who were aged 8-35 years. ATP1A3 emerged as the disease-associated gene in AHC. Whole-exome sequencing showed three heterozygous de-novo missense mutations. Sequencing of the 21 remaining affected individuals identified disease-associated mutations in ATP1A3 in all patients, including six de-novo missense mutations and one de-novo splice-site mutation. Because ATP1A3 is also the gene associated with rapid-onset dystonia-parkinsonism (DYT12, OMIM 128235) we compared the genotypes and phenotypes of patients with AHC in our cohort with those of patients with rapid-onset dystonia-parkinsonism reported in the scientific literature. We noted overlapping clinical features, such as abrupt onset of dystonic episodes often triggered by emotional stress, a rostrocaudal (face to arm to leg) gradient of involvement, and signs of brainstem dysfunction, as well as clearly differentiating clinical characteristics, such as episodic hemiplegia and quadriplegia. Interpretation Mutation analysis of the ATP1A3 gene in patients who met clinical criteria for AHC allows for definite genetic diagnosis and sound genetic counselling. AHC and rapid-onset dystonia-parkinsonism are allelic diseases related to mutations in ATP1A3 and form a phenotypical continuum of a dystonic movement disorder."],["dc.identifier.doi","10.1016/S1474-4422(12)70182-5"],["dc.identifier.gro","3142472"],["dc.identifier.isi","000307911700011"],["dc.identifier.pmid","22850527"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/11305"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/8662"],["dc.notes.intern","WoS Import 2017-03-10 / Funder: Eva Luise and Horst Kohler Foundation for Humans with Rare Diseases"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","final"],["dc.notes.submitter","PUB_WoS_Import"],["dc.publisher","Elsevier Science Inc"],["dc.relation.eissn","1474-4465"],["dc.relation.issn","1474-4422"],["dc.rights","Goescholar"],["dc.rights.uri","https://goescholar.uni-goettingen.de/licenses"],["dc.title","Heterozygous de-novo mutations in ATP1A3 in patients with alternating hemiplegia of childhood: a whole-exome sequencing gene-identification study"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.subtype","original"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]Details DOI PMID PMC WOS2014Journal Article [["dc.bibliographiccitation.artnumber","74"],["dc.bibliographiccitation.journal","Molecular Cytogenetics"],["dc.bibliographiccitation.volume","7"],["dc.contributor.author","Schwaibold, Eva Maria Christina"],["dc.contributor.author","Smogavec, Mateja"],["dc.contributor.author","Hobbiebrunken, Elke"],["dc.contributor.author","Winter, Lorenz"],["dc.contributor.author","Zoll, Barbara"],["dc.contributor.author","Burfeind, Peter"],["dc.contributor.author","Brockmann, Knut"],["dc.contributor.author","Pauli, Silke"],["dc.date.accessioned","2018-11-07T09:33:25Z"],["dc.date.available","2018-11-07T09:33:25Z"],["dc.date.issued","2014"],["dc.description.abstract","Background: Kleefstra syndrome is characterized by intellectual disability, muscular hypotonia in childhood and typical facial features.

At least one regulatory, missense, or leaky splice site mutation resulting in expression of ATM with low level kinase activity was identified in subjects with variant A‐T. Studies on the pathogenicity of the germline splicing ATM variant c.1066‐6T\\u0026gt;G have provided conflicting results. Using whole‐exome sequencing, we identified two splice site ATM variants, c.1066‐6T\\u0026gt;G; [p.?], and c.2250G\\u0026gt;A, [p.Ile709_Lys750del], in a compound heterozygous state in a 27‐year‐old woman who had been diagnosed as having congenital ocular motor apraxia type Cogan in her childhood. Reappraisal of her clinical phenotype revealed consistency with variant A‐T. Functional analyses showed reduced expression of ATM protein and residual activity of the ATM kinase at a level consistent with variant A‐T.

TBC1D24 mutations, identified through various sequencing methods, can be found online (http://lovd.nl/TBC1D24).Results:Forty-eight patients were included (28 men, 20 women, average age 21 years) from 30 independent families. Eighteen patients (38%) had myoclonic epilepsies. The other patients carried diagnoses of focal (25%), multifocal (2%), generalized (4%), and unclassified epilepsy (6%), and early-onset epileptic encephalopathy (25%). Most patients had drug-resistant epilepsy. We detail EEG, neuroimaging, developmental, and cognitive features, treatment responsiveness, and physical examination. In silico evaluation revealed 7 different highly conserved motifs, with the most common pathogenic mutation located in the first. Neuronal outgrowth assays showed that some TBC1D24 mutations, associated with the most severe TBC1D24-associated disorders, are not necessarily the most disruptive to this gene function.Conclusions:TBC1D24-related epilepsy syndromes show marked phenotypic pleiotropy, with multisystem involvement and severity spectrum ranging from isolated deafness (not studied here), benign myoclonic epilepsy restricted to childhood with complete seizure control and normal intellect, to early-onset epileptic encephalopathy with severe developmental delay and early death. There is no distinct correlation with mutation type or location yet, but patterns are emerging. Given the phenotypic breadth observed, TBC1D24 mutation screening is indicated in a wide variety of epilepsies.
