ICD-11 code : 5C51.20;
Preferred Label : Primary hyperoxaluria type 1;
ICD-11 definition : Primary hyperoxaluria type 1 is a rare metabolic disorder due to a defect of the peroxysomal
hepatic enzyme L-alanine: glyoxylate aminotransferase (AGT). The infantile form is
characterized by chronic renal failure due to massive oxalate deposition. In other
patients, urolithiasis develops with infections, hematuria, renal colics or acute
renal failure due to complete obstruction. End-stage renal failure occurs before 15
years of age in half the cases and the resulting increase of circulating oxalate leads
to its deposition in tissues causing cardiac conduction defects, hypertension, distal
gangrene, and reduced joint mobility and pain.;
