2.7.1.60 | malfunction |
enzyme mutations can cause sialuria and hereditary inclusion body myopathy. Sialuria patients have a heterozygous missense mutation affecting the allosteric site of GNE, leading to loss of feedback inhibition of GNE-epimerase activity by CMP-Neu5Ac, resulting in excessive sialic acid production. HIBM and its allelic Japanese disorder, distal myopathy with rimmed vacuoles, or DMRV, is an autosomal recessive neuromuscular disorder of adult onset, characterized byslowly progressive muscle weakness and atrophy |

heterozygous UDP-GlcNAc 2-epimerase and N-acetylmannosamine kinase domain mutations in the GNE gene result in a less severe GNE myopathy phenotype compared to homozygous N-acetylmannosamine kinase domain mutations, screening study of mutant individuals, genotypes of the GNE myopathy patient population and phenotypes, overview |

2.7.1.60 | malfunction |
non-allosteric GNE gene mutations cause the muscular disorder GNE myopathy, i.e. hereditary inclusion body myopathy. Complete Gne knockout is embryonically lethal. Transgenic mice expressing the human GNE cDNA with the D176V mutation, common among Japanese patients, in a mouse background with a disrupted mouse Gne gene recapitulates the adult onset features of human GNE myopathy with hyposialylation in serum and different organs. M712T mouse mutants die within 72 h of birth from severe glomerular disease. Mouse isozyme mutant phenotypes, overview |

2.7.1.60 | malfunction |
silencing of GNE sensitizes pancreatic cancer cells to anoikis, an apoptosis program activated on loss of matrix anchorage. A loss of GNE enzyme activity in cells renders them anoikis-susceptible after transfection with the tumor suppressor p16. ManNAc incubation reduces anoikis susceptibility, phenotype, overview. Enzyme up-regulation occurs predominantly in pancreatic cancer but also in other malignancies |
