I suggest you contact Dr Garone at Coumbia University in New York to discuss and arrange this testing---they also do the gene testing for TYMP mutations which are the cause of MNGIE----reference Garone C et al: Clincal & genetic spectrum of mitochondrial neurogastrointestinal encephalomyopathy.

best regards

Dr. Lynette Fairbanks at the Purine Research Laboratory,

St.Thomas' Hospital, London SE1 7EH measures TP enzyme activity in Leucocytes for MINGIE.

For the next patient we can do it in Maastricht MUMC+.
