Genetic Disorder

Primary Hyperoxaluria

HIGH SEVERITY

A group of rare genetic disorders causing overproduction of oxalate, leading to calcium oxalate kidney stones, nephrocalcinosis, and end-stage renal disease. Three types with different enzyme deficiencies (AGXT, GRHPR, HOGA1).

Risk Factors

1Family history
2Genetic mutations
3Consanguinity
4Advanced paternal age
5Ethnic predisposition

Diagnostic Methods

  • 1Genetic testing
  • 2Clinical evaluation
  • 3Family history assessment
  • 4Specialized laboratory tests
  • 5Imaging studies
  • 6Biopsy (if applicable)

Prognosis

Without treatment, end-stage renal failure develops by age 15-20 in Type 1, later in Type 2. Dialysis is insufficient to remove oxalate. Combined liver-kidney transplant is curative for Type 1 and 2; isolated kidney transplant for Type 3. Pre-emptive liver transplant before renal failure may be considered. Lumasiran (RNAi therapy) significantly reduces oxalate production in Type 1. Intensive dialysis and pyridoxine (Type 1) may delay progression. Early diagnosis critical.

Prevention

  • Genetic counseling
  • Carrier screening
  • Prenatal diagnosis
  • Preimplantation genetic diagnosis
  • Family planning

Research Status

High fluid intake, urinary crystallization inhibitors. Pyridoxine for PH type 1 (some responsive). Lumasiran (RNAi therapy) reduces oxalate production. Combined liver-kidney transplant for ESRD. Early diagnosis critical.
