Abstract:
Objective To analyze the clinical features and genetic background of mitochondrial neurogastrointestinal encephalomyopathy(MNGIE). Methods The clinical data of an adult patient with MNGIE wereretrospectively reviewed. Meanwhile, the mitochondrial disease-related gene of the patient and his families weredetected by target area capture sequencing with NimbleGen solid phase chip. Results This patient presented with progressive pseudo-gastrointestinal obstruction, leukoencephalopathy, cachexia, peripheral neuropathy, extraocularmuscle weakness, and multiple metabolic disorders. A homozygous mutation(TYMP gene c.217G >A) was identified. The patient's parents and sister were heterozygous for this novel mutation. Conclusion A novel TYMP gene mutation that caused MNGIE in a Chinese adult patient was confirmed by gene detection.
