Abstract

A deficiency of the enzyme hypoxanthine-guanine phosphoribosyltransferase (HPRT; EC 2.4.2.8) is associated with a spectrum of disease that ranges from gouty arthritis (OMIM 300323) to the more severe Lesch-Nyhan syndrome (OMIM 300322). To date, all cases of HPRT deficiency have shown a mutation within the HPRT cDNA. In the present study of an individual with gout due to HPRT deficiency, we found a normal HPRT cDNA sequence. This is the first study to provide an example of HPRT deficiency which appears to be due to a defect in the regulation of the gene.
