PSMA6 and sarcoidosis: The relationship between NTM PD and other rare conditions has been less well characterized, but we note here that for several rare comorbid conditions with a prevalence of < 2% in our population, strong associations with NTM PD were observed, including coccidiomycosis (RP = 27), alpha-1 anti-trypsin deficiency (RP = 12), sarcoidosis (RP = 10), lung malignancy (RP = 7), and inflammatory bowel disease (RP = 3).
