PRTN3 and interstitial lung disease: Because the prevalence of ILD is higher in MPO-AAV compared with PR3-AAV [3], and the TERT and DSP SNVs were associated with susceptibility to MPO-AAV as described above, only MPO-AAV patients were examined for the association of these SNVs with the presence of ILD in a case-case study comparing MPO-AAV patients with ILD (MPO-AAV-ILD) and those without ILD (MPO-AAV-noILD) (Table 4).
