- Abstract
Clinical, biochemical, and genetic features of a Spanish family with mitochondrial neurogastrointestinal encephalomyopathy are reported. The proband presented with severe gastrointestinal dysmotility and the affected sister had extraocular muscle weakness. In both affected individuals, biochemical defects of thymidine phosphorylase and a pathogenic G-to-A transition mutation at nucleotide 435 in the thymidine phosphorylase gene were identified. The first thymidine phosphorylase mutation identified in Spain showed phenotypic variability at onset.
