Analysis of the pathogenicity of novel GNE mutations and clinical, pathological, and genetic characteristics of GNE myopathy in Chinese population [PDF]
Background GNE myopathy is a rare autosomal recessive distal myopathy caused by mutations in UDP-N-acetylglucosamine 2-epimerase/N-acetylmannosamine kinase (GNE), a bifunctional enzyme critical for sialic acid biosynthesis. This study aimed to describe a

Novel Mutations in Titin Exon 363 With Different Phenotypes Including a Founder Mutation in Eastern Europe. [PDF]
In six patients from five families, we identified two novel exon 363 pathogenic variants causing recessive titinopathies. Patients with a recurrent Eastern European founder variant presented with juvenile distal titinopathy, while a Belgian family showed an early‐onset titinopathy with contractures.

Alpha-Synuclein as a Potential Biomarker for Inclusion Body Myositis in Blood and Muscle. [PDF]
We examined alpha‐synuclein in muscle and serum samples of patients with IBM and other neuromuscular disorders. With the use of immunohistochemistry, we identify alpha‐synuclein muscular reactivity as a complementary diagnostic marker. Serum alpha‐synuclein levels measured by ELISA were not generally altered in IBM but correlated with disease duration ...

A recurrent GNE variant causing GNE myopathy in unrelated patients from Pakistan: a case series [PDF]
Background GNE myopathy, also referred to as bifunctional UDP-N-acetylglucosamine 2-epimerase/N-acetylmannosamine kinase myopathy, is a progressive distal myopathy marked by rimmed vacuoles and linked to a variety of disease-causing genetic variants ...

SNUPN-Related Muscular Dystrophy: Novel Phenotypic, Pathological and Functional Protein Insights. [PDF]
ABSTRACT Objective SNUPN‐related muscular dystrophy or LGMDR29 is a new entity that covers from a congenital or childhood onset pure muscular dystrophy to more complex phenotypes combining neurodevelopmental features, cataracts, or spinocerebellar ataxia. So far, 12 different variants have been described.

Myotilin gene duplication causing late-onset myotilinopathy. [PDF]
Abstract Background myotilinopathy is a very rare inherited muscle disease that belongs to the group of myofibrillar myopathies. These diseases share a common alteration of the sarcomere organization at the level of the Z disk resulting in pathological protein aggregation, autophagic abnormalities, and ultimately muscle degeneration.

Distal Myopathy with Rimmed Vacuoles Confirmed by Whole Exome Sequencing
Distal myopathy with rimmed vacuoles (DMRV) or hereditary inclusion body myopathy 2 is an autosomal recessive muscular disorder characterized by early adult-onset weakness of distal muscles and rimmed vacuoles in muscle biopsy. Mutations in the UDP-N-acetylglucosamine 2-epimerase/N-ace-tylmannosamine kinase (GNE) gene are associated with the ...
