Mitochondrial neurogastrointestinal encephalomyopathy (MNGIE) syndromes is a rarely seen multisystem disorder with autosomal recessive inheritance due to thymidine phosphorylase gene mutation. It is characterized by progressive external ophthalmoplegia and/or pitosis, progressive gastrointestinal dismotility and abdominal pain, postprandial emesis, cachexia, demyelinating peripheral neuropathy, symmetrical and distal weakness especially in lower extremities and diffuse leucoencephalopathy in cranial magnetic resonance. Endocarditis is the infectious and inflammatory disease of the endothelial surface of the heart. MNGIE syndrome is a condition in which immune system is suppressed and infection risk increased. Herein we summarized a previously not reported endocarditis case in a patient with MNGIE syndrome who was under follow up for three years. In MNGIE syndrome of acute dyspnea, infective endocarditis should be kept in mind and prompt evaluation for surgical treatment should be done.

Inherited deficiency of thymidine phosphorylase (TP), encoded by TYMP, leads to a rare disease with multiple mitochondrial DNA (mtDNA) abnormalities, mitochondrial neurogastrointestinal encephalomyopathy (MNGIE). However, the impact of TP deficiency on lysosomes remains unclear, which are important for mitochondrial quality control and nucleic acid metabolism. Muscle biopsy tissue and skin fibroblasts from MNGIE patients, patients with m.

TYMP gene, which codes for thymidine phosphorylase (TP) is also known as platelet-derived endothelial cell growth factor (PD-ECGF). TP plays crucial roles in nucleotide metabolism and angiogenesis. Mutations in the TYMP gene can lead to Mitochondrial Neurogastrointestinal Encephalopathy (MNGIE) syndrome, a rare genetic disorder.

Article Synopsis
  • - MNGIE (mitochondrial neurogastrointestinal encephalopathy syndrome) is a rare genetic disorder caused by a deficiency in thymidine phosphorylase, leading to serious issues like gastrointestinal problems, muscle weakness, and neurological symptoms.
  • - A case study highlights a 28-year-old man with MNGIE who underwent liver transplantation to improve his symptoms, but still faced ongoing gastrointestinal dysmotility and required nutritional support.
  • - After extensive rehabilitation, he received an intestine transplant 2.5 years post-liver transplant, and four years later, he is off nutritional support and gradually improving, marking a significant milestone in treating this condition.

Mitochondrial neurogastrointestinal encephalomyopathy (MNGIE) syndrome is an extremely rare multisystem disorder with autosomal recessive inheritance and impairs mitochondrial DNA replication, which causes myopathy and neurodegeneration. The classical symptoms of this syndrome are progressive gastrointestinal dysmotility and peripheral neuropathy. We are presenting a patient who had MNGIE syndrome and presented with anejaculation for the first time in the literature.
