Occurrence comments
The mutant PI Mwurzburg is completely retained within synthetising cells and the molecular defect of transportation may be similar to that of the common PI Zallele.
This variant was identified at heterozygous status MwurzburgZ in a 19-year old man presenting with liver cytolysis.
It was also identified at heterozygous status M3Mwurzburg in a 58-year old man presenting with emphysema.
