Alternative titles and symbols : Iminoglycinuria type II; Glycinuria with or without oxalate nephrolithiasis; Glycinuria with or without oxalate urolithiasis;
Description : 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).;
