Ethylmalonic encephalopathy is an inherited disorder that is usually evident at birth and affects several body systems, particularly the nervous system. Neurologic signs and symptoms include progressively delayed development, weak muscle tone (hypotonia), seizures, and abnormal movements. The body's network of blood vessels is also affected. Children with this disorder may experience rashes of tiny red spots (petechiae) caused by bleeding under the skin and blue discoloration in the hands and feet due to reduced oxygen in the blood (acrocyanosis). Chronic diarrhea is another common feature. Ethylmalonic encephalopathy is inherited in an autosomal recessive pattern and caused by mutations in the ETHE1 gene.[1]
