Mutation update for GNE gene variants associated with GNE myopathy. [PDF]

Hum Mutat, 2014
The GNE gene encodes the rate-limiting, bifunctional enzyme of sialic acid biosynthesis, uridine diphosphate-N-acetylglucosamine 2-epimerase/N-acetylmannosamine kinase (GNE). Biallelic GNE mutations underlie GNE myopathy, an adult-onset progressive myopathy. GNE myopathy-associated GNE mutations are predominantly missense, resulting in reduced, but not

Development of Assays to Measure GNE Gene Potency and Gene Replacement in Skeletal Muscle. [PDF]

J Neuromuscul Dis, 2023
Background: GNE myopathy (GNEM) is a severe muscle disease caused by mutations in the UDP-GlcNAc-2-epimerase/ManNAc-6-kinase ( GNE ) gene, which encodes a bifunctional enzyme required for sialic acid (Sia) biosynthesis.

A case report: identification of a novel exon 1 deletion mutation in the GNE gene in a Chinese patient with GNE myopathy. [PDF]

Medicine (Baltimore), 2020
GNE myopathy is caused by mutations in the UDP-N-acetylglucosamine-2-epimerase/N-acetylmannosamine kinase(GNE) gene and is clinically characterized by progressive weakness and atrophy of the lower-limb muscles with quadriceps sparing. Nearly all GNE mutations that have been reported thus far in various ethnic populations around the world have been ...

Novel GNE Gene Variants Associated with Severe Congenital Thrombocytopenia and Platelet Sialylation Defect. [PDF]

Thromb Haemost, 2022
AbstractThe GNE gene encodes an enzyme that initiates and regulates the biosynthesis of N-acetylneuraminic acid, a precursor of sialic acids. GNE mutations are classically associated with Nonaka myopathy and sialuria, following an autosomal recessive and autosomal dominant inheritance pattern.

Preclinical assessment of GNEwt/bi-shRNA-GNEM743T lipoplex product development for GNE myopathy [PDF]

Future Science OA
Aims GNE myopathy is a heredity disease of unmet medical need associated with progressive skeletal muscle wasting, atrophy and weakness caused by mutations in the GNE gene. GNE plays a pivotal role in sialic acid production.

Defective autophagy in GNE myopathy is rescued by inhibition of noncanonical Akt–mTORC1 activation across multiple isogenic models [PDF]

Experimental and Molecular Medicine
GNE myopathy is a recessive autosomal disease caused by mutations in glucosamine (UDP-N-acetyl)-2-epimerase/N-acetylmannosamine kinase (GNE), characterized by impaired sialic acid biosynthesis and the formation of rimmed vacuoles.

Gne-Depletion in C2C12 Myoblasts Leads to Alterations in Glycosylation and Myopathogene Expression [PDF]

Cells
GNE myopathy is a rare genetic neuromuscular disorder caused by mutations in the GNE gene. The respective gene product, UDP-N-acetylglucosamine 2-epimerase/N-acetylmannosamine kinase (GNE), is a bifunctional enzyme that initiates endogenous sialic acid ...
