Prioritization of Deleterious Variations in the Human Hypoxanthine-Guanine Phosphoribosyltransferase Gene
ABSTRACT Background and Objectives: Non-synonymous single nucleotide polymorphisms are typical genetic variations that may potentially affect the structure or function of expressed proteins, and therefore could be involved in complex disorders. A computational-based analysis has been done to evaluate the phenotypic effect of no...
متن کاملHuman hypoxanthine-guanine phosphoribosyltransferase.
A mutant form of human hypoxanthine-guanine phosphoribosyltransferase (HPRTToronto) was isolated from erythrocytes of a male patient with gout due to a partial deficiency of enzyme activity. The tryptic peptides of HPRTToronto were mapped by reverse-phase high pressure liquid chromatography in an attempt to define the precise abnormality in its primary structure. Sequence analysis of the single...
متن کاملHuman Hypoxanthine Phosphoribosyltransferase
Hypoxanthine phosphoribosyltransferase (inosine monophosphate: pyrophosphate phosphoribosyltransferase EC 2.4.2.8) has been purified SO-fold from an acid-treated lysate of human erythrocytes. The average particle weight of the enzyme was estimated by gel filtration at 60,000. Between the pH values of 7.1 and 9.1 no marked difference in the initial velocity of IMP synthesis was observed. Kinetic...
متن کاملFine structure of the human hypoxanthine phosphoribosyltransferase gene.
The human hypoxanthine phosphoribosyltransferase (HPRT) gene has been characterized by molecular cloning, mapping, and DNA sequencing techniques. The entire gene, which is about 44 kilobases in length, is composed of nine exon elements. The positions of the introns within the coding sequence are identical to those of the previously-characterized mouse HPRT gene, although there are significant d...
متن کاملHypoxanthine-Guanine Phosphoribosyltransferase Variant
A B S T R A C T We have previously described a 14-yrold boy with hyperuricemia, renal failure, and accelerated purine production resistant in vivo and in vitro to purine analogs. This patient demonstrated normal red cell hypoxanthine-guanine phosphoribosyltransferase (HPRT) heat stability, electrophoresis at high pH, and activity at standard substrate levels. In the present report an abnormal H...
