Although limb-girdle muscular dystrophies (LGMD) can cause permanent disability, to date there are no studies that examined quality of life (QoL) in these patients. Our aim was to evaluate QoL in patients with LGMD, and to identify the most significant predictors of QoL. The study comprised 46 patients with diagnosis of limb-girdle muscular weakness. QoL in patients was evaluated using two scales-SF-36 questionnaire and the Individualized Neuromuscular Quality of Life questionnaire (INQoL). Following scales were also applied: Epworth Sleepiness Scale (ESS), Hamilton Scale for Depression (HamD), and Krupp's Fatigue Severity Scale (FSS)...

Recently, a new type of limb-girdle muscular dystrophy (LGMD type 2Z) has been identified due to a missense mutation in POGLUT1 (protein O-glucosyltransferase-Rumi), an enzyme capable of adding glucose to a distinct serine residue of epidermal growth factor-like repeats containing a C-X-S-X-(P/A)-C consensus sequence such as Notch receptors. Affected patients demonstrate reduced Notch signaling, decreased muscle stem cell pool and hypoglycosylation of α-dystroglycan, leading to LGMD phenotype. Here we report the generation and characterization of an iPSC line (CSCRMi001-A) from a LGMD-2Z patient with missense mutation in POGLUT1 which can be used for in vitro disease modeling...

BACKGROUND: Limb-girdle muscular dystrophy (LGMD) is the most common adult-onset class of muscular dystrophies in India, but a majority of suspected LGMDs in India remain unclassified to the genetic subtype level. The next-generation sequencing (NGS)-based approaches have allowed molecular characterization and subtype diagnosis in a majority of these patients in India. MATERIALS AND METHODS: (I) To select probable dysferlinopathy (LGMD2B) cases from other LGMD subtypes using two screening methods (i) to determine the status of dysferlin protein expression in blood (peripheral blood mononuclear cell) by monocyte assay (ii) using a predictive algorithm called automated LGMD diagnostic assistant (ALDA) to obtain possible LGMD subtypes based on clinical symptoms...

Autosomal recessive limb-girdle muscular dystrophies (LGMD type 2) are a group of clinically and genetically heterogeneous diseases with the main characteristics of weakness and wasting of the pelvic and shoulder girdle muscles. Among them are sarcoglycanopathies caused by mutations in at least four genes named SGCA, SGCB, SGCG and SGCD. Here we report a consanguineous Iranian family with two children affected with LGMD type 2E. Mutation analysis revealed a novel homozygous exon 2 deletion of SGCB gene in the patients with the parents being heterozygous for this deletion...

Limb-girdle muscular dystrophy (LGMD) 2i results from mutations in fukutin-related protein and aberrant α-dystroglycan glycosylation. Although this significantly compromises muscle function and ambulation, the comprehensive characteristics of contractile dysfunction are unknown. We therefore quantified the in situ contractile properties of the medial gastrocnemius in young adult P448L mice, an affected muscle and novel model of LGMD2i, respectively. Maximal twitch force, tetanic force and power normalized to physiological cross-sectional area were significantly smaller in P448L mice, compared to sex-matched wild-type mice...

Limb-girdle muscular dystrophy 2S (LGMD2S) is an autosomal recessive condition due to mutations in the TRAPPC11 gene. It is recently described with only 9 prior reported individuals. In addition to the muscular dystrophy, some affected individuals have small head size, global developmental delay, seizures, cataracts, and liver problems. Siblings with an uncharacterized LGMD were assessed; whole-exome screening revealed compound heterozygous mutations in the TRAPPC11 gene. Their presentation helps confirm the emerging phenotype for LGMD2S...

Limb-girdle muscular dystrophy types 2D and 2F (LGMD 2D and 2F) are autosomal recessive disorders caused by mutations in the alpha- and delta sarcoglycan genes, respectively, leading to severe muscle weakness and degeneration. The cause of the disease has been well characterized and a number of animal models are available for pre-clinical studies to test potential therapeutic interventions. To facilitate transition from drug discovery to clinical trials, standardized procedures and natural disease history data were collected for these mouse models...

A 41-year-old man presented with gradually progressing proximal-dominant lower limb atrophy and weakness. His brother, mother and maternal aunt had the same symptoms. A physical examination and muscle imaging (CT and ultrasound) showed selective muscle involvement of the bilateral paraspinal, gluteus and posterior groups of lower limb muscles. Based on the characteristic muscle involvement pattern, the clinical findings and the muscle biopsy results, we made a straightforward diagnosis of limb-girdle muscular dystrophy (LGMD) due to a DNAJB6 Phe93Leu mutation based on a targeted gene analysis...

Mutations in the gene encoding the giant skeletal muscle protein titin are associated with a variety of muscle disorders, including recessive congenital myopathies ±cardiomyopathy, limb girdle muscular dystrophy (LGMD) and late onset dominant distal myopathy. Heterozygous truncating mutations have also been linked to dilated cardiomyopathy. The phenotypic spectrum of titinopathies is emerging and expanding, as next generation sequencing techniques make this large gene amenable to sequencing. We undertook whole exome sequencing in four individuals with LGMD...

BACKGROUND: Limb-girdle muscular dystrophies (LGMDs) are a heterogeneous group of inherited autosomal myopathies that preferentially affect voluntary muscles of the shoulders and hips. LGMD has been clinically described in several breeds of dogs, but the responsible mutations are unknown. The clinical presentation in dogs is characterized by marked muscle weakness and atrophy in the shoulder and hips during puppyhood. METHODS: Following clinical evaluation, the identification of the dystrophic histological phenotype on muscle histology, and demonstration of the absence of sarcoglycan-sarcospan complex by immunostaining, whole exome sequencing was performed on five Boston terriers: one affected dog and its three family members and one unrelated affected dog...

Telethoninopathy is one of the rarest forms of Limb-girdle muscular dystrophy (LGMD). So far, only a small number of LGMD type 2 G (LGMD2G) patients have been described, mostly patients from Brazil. Here we present a 35-year-old female patient of Turkish ethnicity with LGMD2G due to a novel homozygous frame-shift mutation c.90_91del (p.Ser31Hisfs*11) in the telethonin gene, probably leading to truncated protein or nonsense mediated decay. Myalgia and walking on tiptoes were the first symptoms starting in early childhood, around age 22 proximal, later distal leg muscles became affected...

Mutations in GMPPB gene have been reported in patients with early-onset disease ranging from severe congenital muscular dystrophies to limb-girdle muscular dystrophy (LGMD) with mental retardation. More recently mutations in GMPPB have been identified with congenital myasthenic syndromes as well as milder phenotypes. We report two unrelated cases with LGMD that underwent clinical, histopathological and genetic studies. In both cases, we found identical compound heterozygous GMPPB mutations c.79G>C p.D27H and c...
