Insights
Primary hyperoxaluria type 1 is a genetic kidney disease. A common AGXT gene mutation was found in three Indian children, highlighting the need for targeted genetic screening.
Area of Science:
- Genetics
- Nephrology
- Biochemistry
Background:
- Primary hyperoxaluria type 1 (PH1) is an inherited metabolic disorder.
- It results from a deficiency in the AGXT gene, encoding alanine-glyoxylate aminotransferase.
- PH1 leads to oxalate overproduction and kidney damage.
Observation:
- Three Indian children with PH1 were studied.
- All presented with chronic kidney disease (CKD).
- A shared mutation in the AGXT gene was identified in all patients.
Findings:
- The study identified a common AGXT gene mutation in three Indian children with PH1.
- All affected children showed signs of CKD at diagnosis.
- Progression to end-stage renal disease (ESRD) was observed in these patients.
Implications:
- The findings suggest a specific AGXT mutation is prevalent in this Indian cohort.
- Targeted genetic screening for this mutation could aid early PH1 diagnosis.
- Early diagnosis and intervention may alter the course of kidney disease in PH1.
Abstract:
Primary hyperoxaluria is an autosomal recessive disorder caused by deficiency of alanine-glyoxylate aminotransferase, which is encoded by the AGXT gene. We report three Indian children with primary hyperoxaluria type1 having a common mutation in this gene. All patients had evidence of chronic kidney disease at the time of diagnosis, with subsequent progression to end-stage renal disease. The detection of an identical mutation in the AGXT gene suggests that specific genetic screening for this mutation may be useful when considering the diagnosis of primary hyperoxaluria type1.

Translation
Translation is the process of synthesizing proteins from the genetic information carried by messenger RNA (mRNA). Following transcription, it constitutes the final step in the expression of genes. This process is carried out by ribosomes, complexes of protein and specialized RNA molecules. Ribosomes, transfer RNA (tRNA), and other proteins produce a chain of amino acids—the polypeptide—as the end product of translation.
