WebApr 7, 1998 · Phosphomannose isomerase was found to be deficient and the defect was present in leucocytes, fibroblasts, and liver tissue. Phosphomannose isomerase deficiency appears to be a novel glycosylation disorder, which is biochemically indistinguishable from CDG syndrome type I. However, the clinical presentation is entirely different. WebPROSITE methods (with tools and information) covered by this documentation: PMI_I_1, PS00965; Phosphomannose isomerase type I signature 1 (PATTERN) Consensus pattern: Y-x-D-x-N-H-K-P-E E is a zinc ligand; Sequences in UniProtKB/Swiss-Prot …
WebMay 17, 2009 · The most common form of CDG, called Type Ia (CDG-Ia), is caused by defects in PMM2 (Man-6-P to Man-1-P), the gene that encodes phosphomannomutase.
