UDP-N-acetylglucosamine 2-epimerase/N-acetylmannosamine kinase
Thre protein product of the GNE gene is involved in sialic acid modification on the cell surface. Mutation cause autosomal recessive or dominant disorders either French type sialuria or Nonaka myopathy.
Interpretation
Three autosomal recessive disorders are caused by mutation of the GNE gene. Mutations located in the sugar kinase domain cause Nonaka myopathy, in epimerase or kinase domain or both inclusion body myopathy, and epimerase domain sialuria.
