Myelination disturbance in a patient with hyperuricemia and hyperserotoninemia combined with 18q deletion syndrome.

Abstract

We previously reported a male patient with an 18q21.3 deletion, hyperuricemia and typical symptoms of the Lesch-Nyhan syndrome who lacked hypoxanthine-guanine-phosphoribosyl-transferase (HGPRT) deficiency. The patient developed progressive peripheral neuropathy in additon to his profound mental retardation and self-injurious behavior. At the age of 23 years MR imaging revealed globally delayed myelination with relative sparing of the corpus callosum and frontal lobes. They were focal hyperintensities suggestive of gliosis. Multimodality evoked potentials found evidence of impaired central and peripheral conduction. Single photon emission computed tomographic (SPECT) imaging demonstrated left frontal hyperperfusion and under it a temporoparietal hypoperfusion.
