CISMeF acronym : HRH;
Type : Phenotype, molecular basis known;
Alternative titles and symbols : Gout, hprt-related; Hprt1 deficiency, partial; Hypoxanthine guanine phosphoribosyltransferase 1 deficiency, partial; Hprt deficiency, partial; Kelley-seegmiller syndrome;
Description : Virtually complete deficiency of HPRT residual activity is associated with the Lesch-Nyhan
syndrome (LNS; 300322), whereas partial deficiency (at least 8%) is associated with
the Kelley-Seegmiller syndrome. LNS is characterized by abnormal metabolic and neurologic
manifestations. In contrast, Kelley-Seegmiller syndrome is usually associated only
with the clinical manifestations of excessive purine production. Renal stones, uric
acid nephropathy, and renal obstruction are often the presenting symptoms of Kelley-Seegmiller
syndrome, but rarely of LNS. After puberty, the hyperuricemia in Kelley-Seegmiller
syndrome may cause gout (summary by Zoref-Shani et al., 2000).;
