Brief Summary:
Researchers are trying to assess whether the use of simple sugars given as a daily dietary supplement can improve the health of children with congenital disorders of glycosylation (CDG).

Condition or disease
Congenital Disorder of Glycosylation

Detailed Description:
The goal of this study is to collect data from patients diagnosed with congenital disorders of glycosylation and taking a simple sugar supplement. The study team wants to expand the evidence on the beneficial effects of this treatment in clinical practice.

Primary Outcome Measures :
  1. Measuring effects of oral monosaccharide supplements through growth measurements [ Time Frame: length of study, up to 2 years ]
    To assess the effects of oral monosaccharide supplementation for each participant, changes in participant growth parameters, as well as blood sugar levels, coagulation parameters, liver function, and other measures of organ system function (as appropriate for the specific type of CDG) will be correlated with biomarkers derived from participant blood and urine samples obtained at key time points and then compared to standard normative ranges of data for each measure.

  2. Measuring effects of oral monosaccharide supplements through blood sugar levels [ Time Frame: length of study, up to 2 years ]
    To assess the effects of oral monosaccharide supplementation for each participant, changes in participant growth parameters, as well as blood sugar levels, coagulation parameters, liver function, and other measures of organ system function (as appropriate for the specific type of CDG) will be correlated with biomarkers derived from participant blood and urine samples obtained at key time points and then compared to standard normative ranges of data for each measure.

  3. Measuring effects of oral monosaccharide supplements through liver function results [ Time Frame: length of study, up to 2 years ]
    To assess the effects of oral monosaccharide supplementation for each participant, changes in participant growth parameters, as well as blood sugar levels, coagulation parameters, liver function, and other measures of organ system function (as appropriate for the specific type of CDG) will be correlated with biomarkers derived from participant blood and urine samples obtained at key time points and then compared to standard normative ranges of data for each measure.

  4. Measuring effects of oral monosaccharide supplements through coagulation results [ Time Frame: length of study, up to 2 years ]
    To assess the effects of oral monosaccharide supplementation for each participant, changes in participant growth parameters, as well as blood sugar levels, coagulation parameters, liver function, and other measures of organ system function (as appropriate for the specific type of CDG) will be correlated with biomarkers derived from participant blood and urine samples obtained at key time points and then compared to standard normative ranges of data for each measure.
