The aim of the thesis is to characterise and model N-glycosylation in skin fibroblasts from patients with galactosaemia. The study identifies a disturbance in the synthesis and processing of dolichol-linked oligosaccharides. It is anticipated that the serum glycoproteins in untreated galactosaemia may contain N-glycans that are partly absent or truncated. / Thesis (M.D.)--University of Adelaide, Dept. of Paediatrics, 1997
