Mitochondrial neurogastrointestinal encephalomyopathy (MNGIE, MIM 603041) is an autosomal recessive multisystem disorder occurring due to mutations in a nuclear gene coding for the enzyme thymidine phosphorylase (TYMP). Clinical features of MNGIE include gastrointestinal dysmotility, cachexia, ptosis or ophthalmoparesis, peripheral neuropathy, diffuse leukoencephalopathy, and signs of mitochondrial dysfunction in tissues. We report the clinical and molecular findings in two brothers in whom novel TYMP gene mutations (c.215-13_215delinsGCGTGA; c. 1159 + 2T > A) were associated with different clinical presentations and outcomes.
