iminoglycinuria
[ĭ-me″no-gli″sin-u´re-ah] a benign hereditary disorder of renal tubular reabsorption of
glycine,
proline, and
hydroxyproline, marked by excessive levels of all three substances in the urine.

i·mi·no·gly·ci·nu·ri·a
(i-mē'nō-glī'si-nyū'rē-ă), [MIM*242600] A benign inborn error of amino acid transport in renal tubule and intestine; glycine, proline, and hydroxyproline are excreted in the urine; probably autosomal recessive inheritance; genetic heterogeneity is suggested.

iminoglycinuria
A disorder (OMIM:242600) of renal tubular reabsorption of glycine and imino acids (proline and hydroxyproline), marked by excessive levels of all three substances in the urine.
Molecular pathology
Caused by defects of:
• SLC6A19, which encodes a protein that actively transports neutral amino acids, especially leucine, across the apical membrane of intestinal and renal epithelial cells;
• SLC6A20, which encodes a transporter that mediates the uptake of imino acids (e.g., L-proline) and glycine;
• SLC36A2, which encodes a pH-dependent proton-coupled amino acid transporter that primarily transports small amino acids (e.g., glycine, alanine and proline).Segen's Medical Dictionary. © 2012 Farlex, Inc. All rights reserved.
iminoglycinuria
Familial iminoglycinuria Molecular medicine A benign AR condition characterized by defective tubular resorption and urinary spilling of proline, hydroxyproline and glycine; iminoglycinuria is a normal physiologic event that occurs in neonates, whose renal transport mechanisms are immature; iminoglycinuria may also occur in Fanconi syndrome and hyperprolinemia.
