Abstract
Here we introduce the human induced pluripotent stem cell lines (hiPSCs), HIMRi004-A and HIMRi005-A from dermal fibroblasts of a 48-year-old female (HIMRi004-A) carrying missense mutation that translate to the first described filamin C isoform p.W2710X and from a 56-year-old female (HIMRi005-A) carrying a recently described mutation in the same domain p.Y2704X. Both lines are generated via lentiviral expression of OCT4, SOX2, KLF4 and c-MYC. The lines display a typical embryonic stem cell-like morphology, express pluripotency markers, retain a normal karyotype (46, XX) and have the differentiation capacity in all three germ layers. The two lines can be used to elucidate the pathomechanisms of FLNC myofibrillar myopathies and to develop novel therapeutic options.

Abstract
Here we introduce the human induced pluripotent stem cell lines (hiPSCs), HIMRi002-A and HIMRi003-A, generated from cultured dermal fibroblasts of 61-year-old (HIMRi002-A) and 38-year-old (HIMRi003-A) female patients, carrying a known heterozygous pathogenic variant (p.A46T) in the Caveolin 3 (CAV3) gene, via lentiviral expression of OCT4, SOX2, KLF4 and c-MYC. HIMRi002-A and HIMRi003-A display typical embryonic stem cell-like morphology, carry the p.A46T CAV3 gene mutation, express several pluripotent stem cell markers, retain normal karyotype (46, XX) and can differentiate in all three germ layers. We postulate that the HIMRi002-A and HIMRi003-A iPSC lines can be used for the characterization of CAV3-associated pathomechanisms and for developing new therapeutic options.

Abstract
Here we introduce the human induced pluripotent stem cell (hiPSC) line HIMRi001-A generated from cultured dermal fibroblasts of a 60-year-old male patient with a myofibrillar myopathy, carrying a heterozygous c.4984C > T [p.Q1662X] mutation in the filamin C (FLNC)-gene, via lentiviral expression of OCT4, SOX2, KLF4 and c-MYC. HIMRi001-A displays typical embryonic stem cell-like morphology, carries the c.4984C > T FLNC gene mutation, expressed several pluripotent stem cell makers, retained normal karyotype (46, XY) and holds the potential to differentiate in all three germ layers. We postulate that HIMRi001-A can be used for the elucidation of FLNC-associated pathomechanisms and for developing new therapeutic options.

Abstract
BACKGROUND Myotonic Dystrophies type 1 and type 2 are hereditary myopathies with dystrophic muscle degeneration in varying degrees. Differences in muscle diffusion between both diseases have not been evaluated yet. OBJECTIVE To evaluate the ability to of muscle diffusion tensor imaging (mDTI) and Dixon fat-quantification to distinguish between Myotonic dystrophy (DM) type 1 and type 2 and if both diseases show distinct muscle involvement patterns. METHODS We evaluated 6 thigh and 7 calf muscles (both legs) of 10 DM 1 and 13 DM 2 and 28 healthy controls (HC) with diffusion tensor imaging, T1w and mDixonquant sequences in a 3T MRI scanner. The quantitative mDTI-values axial diffusivity (λ1), mean diffusivity (MD), radial diffusivity (RD) and fractional anisotropy (FA) as well as fat-fraction were analysed. CTG-Triplett repeat-length of DM 1 patients was correlated to diffusion metrics and fat-fraction. RESULTS mDTI showed significant differences between DM 1 and DM 2 vs. healthy controls in diffusion parameters of the thigh (all p < 0.001) except for FA (p = 0.0521 / 0.8337). In calf muscles mDTI showed significant differences between DM 1 and DM 2 patients (all p < 0.0001) as well as between DM 1 patients and controls (all p = 0.0001). Thigh muscles had a significant higher fat-fraction in both groups vs. controls (p < 0.05). There was no correlation of CTG triplet length with mDTI values and fat-fraction. DISCUSSION mDTI reveals specific changes of the diffusion parameters and fat-fraction in muscles of DM 1 and DM 2 patients. Thus, the quantitative MRI methods presented in this study provide a powerful tool in differential diagnosis and follow-up of DM 1 and DM 2, however, the data must be validated in larger studies.

Abstract
UNLABELLED Desminopathy is a subtype of myofibrillar myopathy caused by desmin mutations and characterized by protein aggregates accumulating in muscle fibers. The aim of this study was to assess the protein composition of these aggregates. Aggregates and intact myofiber sections were obtained from skeletal muscle biopsies of five desminopathy patients by laser microdissection and analyzed by a label-free spectral count-based proteomic approach. We identified 397 proteins with 22 showing significantly higher spectral indices in aggregates (ratio >1.8, p<0.05). Fifteen of these proteins not previously reported as specific aggregate components provide new insights regarding pathomechanisms of desminopathy. Results of proteomic analysis were supported by immunolocalization studies and parallel reaction monitoring. Three mutant desmin variants were detected directly on the protein level as components of the aggregates, suggesting their direct involvement in aggregate-formation and demonstrating for the first time that proteomic analysis can be used for direct identification of a disease-causing mutation in myofibrillar myopathy. Comparison of the proteomic results in desminopathy with our previous analysis of aggregate composition in filaminopathy, another myofibrillar myopathy subtype, allows to determine subtype-specific proteomic profile that facilitates identification of the specific disorder. BIOLOGICAL SIGNIFICANCE Our proteomic analysis provides essential new insights in the composition of pathological protein aggregates in skeletal muscle fibers of desminopathy patients. The results contribute to a better understanding of pathomechanisms in myofibrillar myopathies and provide the basis for hypothesis-driven studies. The detection of specific proteomic profiles in different myofibrillar myopathy subtypes indicates that proteomic analysis may become a useful tool in differential diagnosis of protein aggregate myopathies.

Abstract
Metabolic myopathies include a broad group of diseases involving inherited enzyme defects in the various metabolic pathways and skeletal musculature. They show an extensive phenotypic variability of symptoms and different ages of manifestation. Symptoms often included intolerance to duress or permanent paresis. Some forms of metabolic myopathy, in particular mitochondriopathy, are associated with multsystemic organ participation. The diagnostics must be adjusted to individual cases and carried out in stages. Primary investigations should include blood parameters (e.g. creatine kinase measurement, muscle load tests and determination of the acylcarnitine spectrum) and a second step includes muscle biopsy for histological and enzyme investigations and special molecular genetic tests although the causative enzyme defect cannot be clarified in every case. On the other hand by means of a thorough investigation it is particularly important in patients with load intolerance to differentiate between other causes, in particular psychosomatic diseases. If this is not done there is a danger of classifying the symptoms of a metabolic myopathy as a somatoform disorder. Therapy is mostly symptom-oriented as Pompe disease is the only one which can be treated with enzyme replacement therapy.

Abstract
HISTORY AND ADMISSION FINDINGS An 83-year-old patient with Parkinson's disease was referred because of pain in the thoracolumbar spine, increasing kyphosis and gait disturbance. Clinically, the main anomaly was a marked hyperkyphosis of the spine during standing and sitting which regressed while recumbent. INVESTIGATIONS Radiologically, spondylosis, osteochondrosis, and facet joint arthrosis demonstrated marked degeneration of the spine (diffuse skeletal hyperostosis, DISH). But the postural disorder could not adequately be explained by these pathological changes. The sacroiliac joints were age-appropriate, syndesmophytes or ankylosis typically of AS were not detectable. DIAGNOSIS, TREATMENT AND COURSE A diagnosis of camptocormia in connection with the known Parkinson's disease was made together with the neurologist. Intensive physio- and balneotherapy, the administration of non-steroidal anti-inflammatory drugs (NSAIDs) and an intensification of the Parkinson medication led to a slight improvement of gait disturbance and pain, but not of the tendency to hyperkyphosis. CONCLUSION In the differential diagnosis of postural disorders in spinal diseases, especially in case of hyperkyphosis, camptocormia is of importance as a rare manifestation of different diseases, such as Parkinson's disease. The treatment of camptocormia is difficult and usually not satisfactory.

Abstract
UNLABELLED In patients with late-onset glycogen storage disease type II, one mutation, c.-32-13T>G, in the α-glucosidase (GAA) gene is identified frequently in European populations from different regions along with many rarer mutations. We have performed molecular genetic investigations in 18 German index patients with late-onset disease. The c.-32-13T>G, c.525delT (p.Glu176fsX45), and c.2481+102_2646+31del mutations were detected by PCR/restriction enzyme digest. Other mutations were detected by sequencing. All patients were compound heterozygous and 17 patients harboured the c.-32-13T>G mutation. Seven other previously described mutations (including the c.-32-13T>G) were identified, of which the p.C103G (c.307T>G) and the c.2481+102_2646+31del mutations were present each in three unrelated patients. Sequencing revealed five novel mutations. CONCLUSIONS Genetic testing was able to identify the genetic defects in all patients and screening of the c.-32-13T>G mutation identified 94% of the cases. This is important for quick and reliable diagnosis, especially in view of enzyme replacement. Among the rarer mutations, c.2481+102_2646+31del and p.C103G are rather frequent in Germany.

Abstract
OBJECTIVE To compare muscle imaging findings in different subtypes of myofibrillar myopathies (MFM) in order to identify characteristic patterns of muscle alterations that may be helpful to separate these genetic heterogeneous muscular disorders. METHODS Muscle imaging and clinical findings of 46 patients with MFM were evaluated (19 desminopathy, 12 myotilinopathy, 11 filaminopathy, 1 alphaB-crystallinopathy, and 3 ZASPopathy). The data were collected retrospectively in 43 patients and prospectively in 3 patients. RESULTS In patients with desminopathy, the semitendinosus was at least equally affected as the biceps femoris, and the peroneal muscles were never less involved than the tibialis anterior (sensitivity of these imaging criteria to detect desminopathy in our cohort 100%, specificity 95%). In most of the patients with myotilinopathy, the adductor magnus showed more alterations than the gracilis muscle, and the sartorius was at least equally affected as the semitendinosus (sensitivity 90%, specificity 93%). In filaminopathy, the biceps femoris and semitendinosus were at least equally affected as the sartorius muscle, and the medial gastrocnemius was more affected than the lateral gastrocnemius. The semimembranosus mostly showed more alterations than the adductor magnus (sensitivity 88%, specificity 96%). Early adult onset and cardiac involvement was most often associated with desminopathy. In patients with filaminopathy, muscle weakness typically beginning in the 5th decade of life was mostly pronounced proximally, while late adult onset (>50 years) with distal weakness was more often present in myotilinopathy. CONCLUSIONS Muscle imaging in combination with clinical data may be helpful for separation of distinct myofibrillar myopathy subtypes and in scheduling of genetic analysis.

Abstract
BACKGROUND Myopathies present with a broad diagnostic spectrum which may ultimately require muscle biopsy. MRI has been established as a non-invasive method in diagnosing adult myopathies; not only does MRI reveal characteristic findings which point in a diagnostic direction, but also aids in determining optimal biopsy sites and controlling therapeutic interventions. Muscle MRI is increasingly finding application to pediatric myopathies, especially dystrophies and myositides. The following paper serves to illustrate the use of MRI using exemplary clinical vignettes. PATIENTS/METHODS From 1999 until 2006, 180 children with myopathies of unknown aetiology, ages 10 months to 18 years, were examined with a standardised MRI protocol (axial T1-SE and T2-weighted TIRM sequences). The protocol included imaging of the lower extremities whereas sequences displaying the upper extremities were only acquired in selected patients. Furthermore, intravenous contrast agent was only administered in selected children. RESULTS All investigations could be performed without sedation due to an examination time of 12 to 15 minutes. The illustrated cases of limb-girdle muscular dystrophy, Duchenne's muscular dystrophy, dermatomyositis, pyomyositis, and chronic neurogenic disease with secondary myopathy all showed disease-characteristic MRI patterns which substantially helped to reach the ultimate diagnosis. CONCLUSIONS Muscle MRI is a non-invasive and effective instrument in helping to diagnose pediatric myopathies of unknown aetiology. It may facilitate muscle biopsy and serves to control therapeutical effects and disease course. Furthermore, muscle MRI may be applicated even to children of less than 4 years of age without sedation.

Abstract
HISTORY AND ADMISSION FINDINGS A 53-year-old male was admitted with an acute brainstem syndrome. He developed a severe fluctuating psychosis. Because of the worsening neurological symptoms he was admitted to our neurological clinic five months after onset of the disease. On admission he showed signs of a productive psychosis in addition to akinetic-rigid parkinsonism and cerebellar symptoms. INVESTIGATIONS Laboratory tests revealed a HBeAg-negative hepatitis B. The initial neuroradiolgical studies showed multiple supratentorial and periventricular ischemic and hemorrhagic lesions. MR-angiography and conventional cerebral angiography demonstrated multiple irregularities of the intracranial vessels and vascular occlusions, findings which were compatible with cerebral vasculitis. DIAGNOSIS, THERAPY AND COURSE The laboratory and neuroradiological studies indicated a hepatitis B-associated polyarteriitis nodosa and cerebral vasculitis. He was given oral immunsuppressive therapy (prednisolone 60 mg daily) and virostatic drug (lamivudine 100 mg daily). When the steroid dosis was reduced to 40 mg prednisolon a severe relapse of the encephalopathy occurred which was treated with the atypical antipsychotic drug risperidon, 3 mg daily, and intravenous methylprednisolone plus plasmaphereses. Later he was given prednisolone (60 mg daily) and lamivudine (100 mg daily) again which has so far stabilized the clinical course. CONCLUSION The main treatment of the rare hepatitis B-associated polyarteriitis nodosa with cerebral vasculitis consists of oral steroids in combination with antiviral drugs. Depending on the course of the disease an escalating steroid pulse administration and plasmaphereses should be considered.

Abstract
McArdle's disease is caused by genetic defects of the muscle-specific isozyme of glycogen phosphorylase, which block ATP formation from glycogen in skeletal muscle. Creatine supplementation and ketogenic diet have been tested as potential supplements for muscle energy metabolism which may improve muscle symptomatic. Outcome measures were clinical scores describing muscle symptomatic and parameters derived from 31P-MRS examinations on working muscle. In two placebo controlled cross-over studies low dose creatine showed beneficial effects on muscle symptoms and performance whereas high dose creatine distinctly worsened muscle symptomatic in patients. In both studies, however, the absence of an elevation in phosphocreatine indicated the absence of a creatine uptake by the muscle fibre. The effects of creatine on muscle symptomatic may be independent from energy metabolism in muscle. In a case study, ketogenic diet improved muscle symptomatic and performance. However, these effects again did not result in 31P-MRS visible changes in muscle energy metabolism.

Abstract
In 1965, an adult-onset, autosomal dominant disorder with a peculiar scapuloperoneal distribution of weakness and atrophy was described in a large, multi-generation kindred and named 'scapuloperoneal syndrome type Kaeser' (OMIM #181400). By genetic analysis of the original kindred, we discovered a heterozygous missense mutation of the desmin gene (R350P) cosegregating with the disorder. Moreover, we detected DES R350P in four unrelated German families allowing for genotype-phenotype correlations in a total of 15 patients carrying the same mutation. Large clinical variability was recognized, even within the same family, ranging from scapuloperoneal (n = 2, 12%), limb girdle (n = 10, 60%) and distal phenotypes (n = 3, 18%) with variable cardiac (n = 7, 41%) or respiratory involvement (n = 7, 41%). Facial weakness, dysphagia and gynaecomastia were frequent additional symptoms. Overall and within each family, affected men seemingly bear a higher risk of sudden, cardiac death as compared to affected women. Moreover, histological and immunohistochemical examination of muscle biopsy specimens revealed a wide spectrum of findings ranging from near normal or unspecific pathology to typical, myofibrillar changes with accumulation of desmin. This study reveals that the clinical and pathological variability generally observed in desminopathies may not be attributed to the nature of the DES mutation alone, but may be influenced by additional genetic and epigenetic factors such as gender. In addition, mutations of the desmin gene should be considered early in the diagnostic work-up of any adult-onset, dominant myopathy, even if specific myofibrillar pathology is absent.

Abstract
BACKGROUND McArdle disease, a common metabolic myopathy with autosomal recessive inheritance, is caused by a frequent R50X mutation and many rare mutations in the myophosphorylase gene. OBJECTIVES To identify spectrum and frequencies of myophosphorylase gene mutations in a large cohort of patients with McArdle disease, to discuss diagnostic implications, and to analyse genotype-phenotype relationship. METHODS Molecular genetic analysis of 56 index patients with muscle biopsy-proven myophosphorylase deficiency from Germany (n = 35), UK (n = 13), and several other countries (n = 8) was performed using direct sequencing. RESULTS Allele frequency of the R50X mutation was 58%, and 71% of the patients carried this mutation at least on one allele. We detected 26 other less common mutations, 13 of which are novel: G157V, R161C, Q337R, E384K, S450L, G486D, R570W, K575E, IVS6-2A>T, IVS10+1G>A, R650X, c.1354insC, c.1155_1156delGG. There was no genotype-phenotype correlation with respect to age of onset and severity. R270X was the most frequent mutation among the less common mutations reaching an allele frequency of 5% followed by R94W and G686R representing a frequency of 4% each. CONCLUSIONS The study further extends the genetic heterogeneity of myophosphorylase gene mutations showing no mutational hotspot and no genotype-phenotype correlation. Most novel missense mutations were located in secondary structures or active sites of the enzyme. Some of the less common mutations are recurrent with different frequencies within Europe. Ethnic origin and frequency of less common mutations must be considered to establish efficient strategies in molecular genetic testing. Performing molecular testing can avoid muscle biopsy.
