Two most common mutations including c.2179G>A(p.V727M) and c.1853T>C(p.I618T) were detected in majority of tested GNE myopathy cases. c.920T>G(p.F207C) and c.1664C>T(p.A555V) were next common variants detected. Total of 4 novel variants were identified including c.95T>C(p.M32T), c.490_491dupAT, c.920T>G(p.F307C) and c.1822C>A(p.P608T). Rajsthani people share this gene with the founder mutation of Roma.

  3. The differential proteome profile of HEK293 cells overexpressing pathologically relevant recombinant mutant GNE protein (D207V and V603L) was analyzed. Significant reduction in mRNA and protein levels of PrdxIV was observed in GNE mutant cell lines compared with vector control. The ER redox state was significantly affected due to reduced normal GNE enzyme activity.

  4. Thirty-five different mutations in the GNE gene were recorded in a cohort of GNE-myopathy patients from the Indian subcontinent. p.Val727Met is likely to be a founder mutation of Indian subcontinent.

  5. This study showed thatsSeven patients out of 20 were found to have disease-causing mutations in genes associated with inclusion body myopathy genes allowing for inclusion body myopathy in the differential diagnosis or associated with unexpected diagnosis.

  8. The results of this study widen the spectra of mutations to copy number variations encompassing 5'UTR, underscoring the pivotal role of the hGNE1 transcript in GNE myopathy.

  9. the complex crystal structure of the N-terminal epimerase part of human GNE shows a tetramer in which UDP binds to the active site and CMP-Neu5Ac binds to the dimer-dimer interface.

  10. This study confirms that c.2228T>C (p.M743T) is the most prevalent disease-causing variant in the non-Jewish Persian population, but other GNE variants can cause GNE myopathy in this population.

  3. GNE is strongly involved in cardiac tissue and skeletal muscle early survival and organization.

  4. Our findings suggest that GNE expression is induced when myofibers are damaged or regenerating, and that GNE plays a role in muscle regeneration.

  5. These data therefore suggest a role of GNE1 in basic supply of cells with sialic acids, whereas splice variants GNE2 and GNE3 may have a function in fine-tuning of the sialic acid pathway.

  6. sialic acid biosynthesis is involved in proliferation and expression of GNE

  7. inactivation of the UDP-GlcNAc 2-epimerase by gene targeting causes early embryonic lethality in mice, thereby emphasizing the fundamental role of this bifunctional enzyme and sialylation during development

  9. Mutations in the Gne enzyme, which encode the rate-limiting enzyme in sialic acid biosynthesis, are causative of distal myopathies with rimmed vacuoles or hereditary inclusion body myopathy.

GNE Protein Profile

Protein Summary

The protein encoded by this gene is a bifunctional enzyme that initiates and regulates the biosynthesis of N-acetylneuraminic acid (NeuAc), a precursor of sialic acids. It is a rate-limiting enzyme in the sialic acid biosynthetic pathway. Sialic acid modification of cell surface molecules is crucial for their function in many biologic processes, including cell adhesion and signal transduction. Differential sialylation of cell surface molecules is also implicated in the tumorigenicity and metastatic behavior of malignant cells. Mutations in this gene are associated with sialuria, autosomal recessive inclusion body myopathy, and Nonaka myopathy. Alternative splicing of this gene results in transcript variants encoding different isoforms.
