Partial hypoxanthine-guanine phosphoribosyltransferase deficiency due to a newly recognized mutation presenting with renal failure in a one-year-old boy.
We describe the case of a 1-year-old boy with partial hypoxanthine-guanine phosphoribosyltransferase (HPRT) deficiency. At his first visit to the hospital, he was diagnosed with hyperuricemia and irreversible renal failure. The misssense mutation Asp185Gly (554A>G) was identified in exon 8 of his HPRT gene, and this mutation was inherited from the mother.
