Fighting the Cause of Alzheimer’s and GNE Myopathy

Autophagy in GNE Myopathy

Muscle diseases represent specific muscle pathology. The characteristic features as hallmarks of diseases have been historically used to diagnose the patients. The “Rimmed vacuole (RV)” (Figures 1) is one of such characteristic features in certain groups of the diseases. This structure consists of the space (vacuole) and purple granules (rim) within myofibers, while the space is sometimes occup...

Cell stress molecules in the skeletal muscle of GNE myopathy

BACKGROUND Mutations of the UDP-N-acetylglucosamine-2-epimerase/N-acetylmannosamine-kinase (GNE)-gene are causally related to GNE myopathy. Yet, underlying pathomechanisms of muscle fibre damage have remained elusive. In sporadic inclusion body myositis (sIBM), the pro-inflammatory cell-stress mediators αB-crystallin and inducible nitric oxide synthase (iNOS) are crucial markers of the disease ...

GNE Myopathy: Two Clusters with History and Several Founder Mutations

GNE myopathy (previous names: HIBM, DMRV, IBM2) is a unique distal myopathy with quadriceps sparing. This recessively inherited myopathy has been diagnosed in various regions of the world with more than 150 disease-causing mutations already identified. Several of those are proven or suspected to be founder mutations in certain regional clusters and are described in this review. The review also ...

Does Fungal Infection Cause Alzheimers?

Phenotypic stratification and genotype–phenotype correlation in a heterogeneous, international cohort of GNE myopathy patients: First report from the GNE myopathy Disease Monitoring Program, registry portion

GNE myopathy is a rare distal myopathy, caused by mutations in the GNE gene, affecting sialic acid synthesis. Clinical presentation varies from asymptomatic early stage patients to severely debilitating forms. This first report describes clinical presentations and severity of the disease, using data of 150 patients collected via the on-line, patient-reported registry component of the GNE Myopat...
