1 copy of the PI*Z allele, the most common cause of Alpha-1 Antitrypsin Deficiency; likely to be unaffected unless also carrying a PiS allele.

This has been associated with Wegener's Granulomatosis / Granulomatosis with Polyangiitis, a type of Vasculitis. [PMID 9279535] [PMID 7964431][PMID 8889441]

It has also been suggested in small studies that vasculitis may be more severe in patients positive for PiZ allele. [PMID 8889441]

A higher prevalence of the PiZ Allele has also been noted in some small studies of ANCA positive ulcerative colitis. [PMID 10579117]
