Abstract
We report on a rare case of hypoxanthine guanine phosphoribosyl transferase (HGPRT) deficiency that presented in the newborn period with acute renal failure (ARF). The clinical diagnosis was made on the basis of non-oliguric ARF and evidence of crystal nephropathy on renal biopsy. HGPRT deficiency was eventually confirmed by enzymatic and genetic testing, showing a novel point mutation, 293 A>G. Immediate treatment consisted of peritoneal dialysis with, initially, lactate- then bicarbonate-buffered 1.36% glucose solution together with oral administration of allopurinol. Follow-up after more than 4 years continued to show hyper-echogenic kidneys with almost normal renal glomerular function. There continues to be no neurobehavioural abnormalities.
