A case of a childhood onset developmental encephalopathy with a novel de novo truncating variant in the Membrane Protein Palmitoylated 5 (MPP5) gene

Membrane Protein Palmitoylated 5 (MPP5) is a highly conserved apical complex protein, essential for cell polarity. Defects in neuronal cell polarity are associated with neurologic disorders. Only three patients with heterozygous MPP5 de novo variants have been reported so far, with global developmental delay, behavioral changes and in only one case epileptic seizures.
