Kelley-Seegmiller syndrome due to a new variant of the hypoxanthine-guanine phosphoribosyltransferase (I136T) encoding gene (HPRT Marseille).
A patient with hyperuricaemia and gouty arthritis due to a new variant of hypoxanthine-guanine phosphoribosyltransferase is described. The mutation (I136T, HPRT Marseille) is in the phosphoribosylpyrophosphate-binding region of the gene and leads to almost total loss of enzyme activity in erythrocytes, with 5% in lymphocytes. Nevertheless, the patient showed no neurological abnormality.
