Elsewhere in this issue, Kelley and associates (1) have summarized present knowledge of one recently recognized subtype of primary gout, a variety attributable to a marked deficiency of activity of hypoxanthine-guanine phosphoribosyltransferase (PRT). This particular type of gout, which characteristically presents before age 30, is marked by hyperuricemia greater than 9 mg/100 ml, urinary uric acid excretion values above 1,000 mg/day, and in some subjects by neurological abnormalities, megaloblastic marrow changes, or both. The diagnosis is established by assay of PRT activity of erythrocytes.
A total absence of demonstrable activity of this enzyme has been associated with a pediatric syndrome
