Brief Summary:
Researchers are trying to determine the efficacy of a global metabolomic approach in testing for and diagnosing inborn errors of metabolism as opposed to traditional testing methods.

Condition or disease
Congenital Disorders of Glycosylation

Detailed Description:
Residual samples will be tested for a variety of biomarkers that may lead to better understanding of these disorders and help develop treatment options.

Primary Outcome Measures :
  1. Quantify N-linked glycan intermediates in plasma and urine [ Time Frame: length of study, up to 5 years ]
    Measure N-linked glycan intermediates in plasma and urine from PMM2-CDG patients.

  2. Develop quantitative biomarkers for PGM1-CDG patients to monitor the efficacy of galactose therapy. [ Time Frame: length of study, up to 5 years ]
    Measure the 41 plasma N-glycan levels in 9 PGM1-CDG patients before and after galactose therapy.

  3. Develop quantitative biomarkers for SLC35A2-CDG patients and monitor galactose therapy efficacy. [ Time Frame: length of study, up to 5 years ]
    Measure levels of plasma N-glycans from 10 SLC35A2-CDG patients before and after galactose therapy.

  4. Validate biomarker to diagnose and follow NGLY1 deficiency and monitor N-acetylglucosamine (GlcNAc) therapy response. [ Time Frame: length of study, up to 5 years ]
    Measure the level of Sia-Gal-GlcNAc-Asn biomarker excretion during GlCNAc therapy.

  5. Validate novel diagnostic biomarkers for ALG13-CDG [ Time Frame: length of study, up to 5 years ]
    Measure GlcNAc-β-Asn on glycoproteins in the cells from the already available fibroblast of 9 ALG13 patients.


Biospecimen Retention:   Samples With DNA
Stool, urine, DBS, fibroblasts, and blood can be retained for biomarker testing. DNA may be a part of this testing in the future.
