Hyperglycinuria- MedGen UID:
- 107456
- •Concept ID:
- C0543541
- •
- Disease or Syndrome
The imino acids, proline and hydroxyproline, share a renal tubular reabsorptive mechanism with glycine. Iminoglycinuria (IG; 242600), a benign inborn error of amino acid transport, is also a normal finding in neonates and infants under 6 months of age (Chesney, 2001). Early studies of families with iminoglycinuria suggested genetic complexity, with homozygotes developing IG and heterozygotes manifesting only hyperglycinuria (HG) (summary by Broer et al., 2008).
A phenotype of combined glucosuria and glycinuria has been described (see 138070).
