<div class="portlet_content ln">Acute reversible leukoencephalopathy with increased urinary alpha-ketoglutarate (ARLIAK) is an autosomal recessive disorder characterized by acute reversible neurologic deterioration in the context of a febrile illness. The disorder is associated with transient leukoencephalopathy on brain imaging concurrent with the acute episode, as well as persistently increased excretion of dicarboxylic acids, particularly alpha-ketoglutarate (summary by Dewulf et al., 2019). [from <a title="Online Mendelian Inheritance in Man" href="http://www.omim.org" class="defSource" target="_blank">OMIM</a>]</div>
