Abstract
BackgroundMitochondrial neurogastrointestinal encephalopathy (MNGIE) disease is a rare multisystem disorder that mainly affects the digestive and nervous systems. Key features of the disease include cachexia, ptosis, external ophthalmoplegia, peripheral neuropathy and leucoencephalopathy. Symptoms most often begin by age 20 and overlap several other Metabolic and endocrine disorders making the diagnosis challenging. It has been determined that MNGIE is caused by mutations in the gene-encoding thymidine phosphorylase (TP; previously known as endothelial cell growth factor 1).CaseWe herein present the clinical, neuroimaging and molecular findings in a patient with MNGIE caused by a novel homozygous variant of TYMP gene c.1048C>T, which is predicted to result in a premature protein termination (p.Gln350*). TYMP is a gene on chromosome 22q13.33 that encodes TP.ConclusionThis case highlights the importance of good understanding and early recognition of a rare condition like MNGIE, so that the suffering from unnecessary interventional procedures can be avoided and better multidisciplinary care can be implemented for the symptomatic management of the patient.
