Background:
Ethylmalonic encephalopathy is a rare inborn error of metabolism characterized by neurodevelopmental delay / regression, recurrent petechiae, orthostatic acrocyanosis, and chronic diarrhea.
Case Characteristics:
4-year-old boy with developmental regression, chronic diarrhea, petechial spots and acrocyanosis. MRI brain showed T2W/FLAIR hyperintensities in bilateral caudate and putamen. Abnormal acyl-carnitine profile and metabolites on urinary GC-MS analysis suggested the diagnosis.
Intervention:
Sequencing of ETHE1 gene revealed mutations: c.488G>A and c.375+5G>T (novel).
Message:
EE is clinically-recognizable disorder with typical clinical features.
