Attenuated variants of Lesch-Nyhan disease
Lesch-Nyhan disease is a neurogenetic disorder caused by deficiency of the enzyme hypoxanthine-guanine phosphoribosyltransferase. The classic form of the disease is described by a characteristic syndrome that includes overproduction of uric acid, severe generalized dystonia, cognitive disability and self-injurious behaviour. In addition to the classic disease, variant forms of the disease occur...
متن کاملA Cross-Sectional Study of Regional Brain Volume Abnormalities in Lesch-Nyhan Disease and its Variants
Background—Lesch-Nyhan disease (LND) is a rare, X-linked, neurodevelopmental metabolic disorder that results from a near-complete lack of hypoxanthine phosphoribosyl-transferase enzyme activity. LND is characterized by hyperuricemia, motor neurological abnormalities, recurrent self-injury, and cognitive impairment, but its neural substrates remain poorly understood. Methods—In this cross-sectio...
متن کاملProton MR spectroscopy in Lesch-Nyhan disease.
In vivo proton spectra for four patients with Lesch-Nyhan disease and four control subjects matched for age and sex were acquired from voxels (1.5 x 1.5 x 1.5 cm3) placed in the prefrontal cortex and striatum. The patients with Lesch-Nyhan disease had decreased metabolites, especially N-acetylaspartate and glutamate/glutamine, only in the prefrontal cortex as compared with the control group. Th...
متن کاملDopamine function in Lesch-Nyhan disease.
Lesch-Nyhan disease is a disorder of purine metabolism resulting from mutations in the gene for hypoxanthine guanine phosphoribosyl transferase on the X chromosome. It is characterized by hyperuricemia and all of its consequences, as in gout; but in addition, patients have impressive disease of the central nervous system. This includes spasticity, involuntary movements, and retardation of motor...
متن کاملSelf-injury in Lesch-Nyhan disease.
UNLABELLED Parents of 40 patients with Lesch-Nyhan disease completed a questionnaire detailing developmental history, life course, management, medication, factors influencing variability and topography of self-injury. Several conclusions were reached. Characteristics: Biting was the predominant form, perhaps only because of the difficulty of preventing it. There was considerable variability in ...
