- Abstract
- Congenital disorder of glycosylation (CDG) type Ia (PMM2 mutations) is the most common genetic disorder of protein N-glycosylation. The wide clinical spectrum with mild to severe impairment of neurological function and extensive allelic heterogeneity hamper phenotype-genotype comparison. We report on two male adult siblings with the PMM2 mutations c. 385G > A (p.V129M) and c. 422G > A (p.R141H) and partially different clinical phenotype. Patient 2 has a more severe degree of neurological and systemic involvement and a more pronounced decrease in levels of serum glycoproteins. MALDI-TOF mass spectrometry of serum transferrin and alpha-1-antitrypsin shows more pronounced glycosylation defects in the more severely affected patient. Glycoproteomic analysis may reveal differences in CDG-Ia patients with different disease severity and might endorse clinical characterization of CDG-Ia patients. (literal)
