Is HPRT-like Protein Present in Lesch-Nyhan Patients?
The gross structure of the HPRT gene by Southern blotting: 13 of the 15 had mutations that did not involve major gene rearrangements;
The concentration and molecular size of HPRT mRNA by Northern blotting: 12 had HPRT mRNA of apparently normal size and concentration; and (c) The concentration of HPRT protein by radioimmunoassay: 11 of the 15 patients had undetectable amounts of HPRT protein; the other four had 1.3, 50, 72 and 92% of normal.
