La adenina fosforribosiltransferasa, también conocida como APRT, es una enzima codificada La APRT posee el EC La APRT se encuentra funcionalmente relacionada con la hipoxantina-guanina fosforribosiltransferasa ( HPRT). (HGPRT) è un enzima codificato negli esseri umani dal gene HPRT1. L’HGPRT è una transferasi che catalizza la conversione dell’ipoxantina in inosina. pela deficiência na enzima hipoxantina- guanina fosforibosiltransferase. neurológicas em la deficiência de hipoxantina-guanina fosforribosiltransferasa.

Questa reazione trasferisce il gruppo 5-fosforibosile dal 5-fosforibosil 1-pirofosfato alla purina. There it is – results for the hypoxanthine test. With optimal care, few patients live beyond 40 years and most are confined to a wheelchair. Retrieved from ” https: Diagnostic methods Diagnosis is suspected when psychomotor delay occurs in a patient with elevated Ganina in blood and urine.

The cause of neurological and behavioral symptoms is hipoxwntina. At therapeutic concentrations febuxostat does not inhibit other enzymes involved in purine or pyrimidine metabolism, namely, guanine deaminase, hypoxanthine guanine phosphoribosyltransferase, orotate phosphoribosyltransferase, orotidine monophosphate decarboxylase or purine nucleoside phosphorylase.

The action site is in the kidney, specifically in the afferent glomerular artery, this in order that the reaction happens before passing through the filtration bowman’s capsule. It is believed that the uricase degrading the the uric acid, produced large quantities of peroxide oxidants and metabolites, causing the accumulation of these by the shortage of antioxidant enzymes.

The Allantoin and water will be filtered by the glomerulus while oxygen pass to portal circulation. Formation of peroxisome crystalloid core-like structures. In this case we will handle only two applications: Spasticity, hyperreflexia and extensor plantar reflex appear later. For all other comments, please send your remarks via contact us.


Dysarthria, dysphagia, and opisthotonus are frequent. This system decompose uric acida waste product of purine degradation into allantoin and peroxide involving an enzyme called uricase.

Antenatal diagnosis Prenatal diagnosis by amniocentesis or chorionic villus sampling is possible if the mutation has been identified in the family. There is no treatment for the neurological dysfunction.

Prenatal diagnosis by amniocentesis or chorionic villus sampling is possible if the mutation has been identified in the family. On theoretical grounds, therefore, it should be avoided in patients with rare hereditary deficiency of hypoxanthine-guanine phosphoribosyl-transferase HGPRT such as Lesch-Nyhan and Kelley-Seegmiller syndrome.
