Mutational analysis of AGXT gene in Libyan children with primary hyperoxaluria type 1 at Tripoli Children Hospital.

Mutational analysis of AGXT gene in Libyan children with primary hyperoxaluria type 1 at Tripoli Children Hospital. Saudi J Kidney Dis Transpl. 2018 Jan-Feb;29(1):30-38 Authors: Rhuma NR, Fituri OA, Sabei LT Abstract Primary hyperoxaluria type 1 (PH1) is an inborn error of glyoxylate metabolism. It results from genetic mutation of the AGXT gene. The study objective was to verify the clinical and epidemiological patterns of PH1 in Libyan children at Tripoli Children Hospital confirmed by AGXT gene mutation. A descriptive case series study of 53 children with PH1 diagnosed between 1994 and 2015 was carried out in the Nephrology Unit at Tripoli Children Hospital. Diagnosis of PH1 was based on the clinical presentation (renal stones or nephrocalcinosis), positive family history of PH1, and high 24 h urinary oxalate. Sampling for AGXT gene mutation was collected from April 2012 to December. 2015. Among the 53 children included, males composed of 62.3% of patients. Their age at presentation ranged between two months and 20 years with a mean age of 55.4 ± 48 months. The parents of 81.1% of these patients had positive consanguinity. Forty (75.5%) patients were from South West (mountain area), and 16 (40%) of them were from Yefrin. The most common mutation found in this study was c.731T>C (p.lle244thr) seen in 32 (71%) of children, and interestingly, among these patients, 87.1% were homozygous in gene typing, 86.2% had positive history of...
