Iminoglycinuria

Iminoglycinuria is an autosomal recessive or digenic disorder caused by mutation in one of the neutral amino acid transporter genes (SLC36A2, SLC6A20, SLC6A19). The symptoms inlcude urinary excretion of proline, hydroxyplroline nad glycin.

Epidemiology

The prevalence is 1 in 15,000.
