Patients may present with dyspnea, cough and respiratory failure or acute heart block and subsequent sudden cardiac death, depending on the affected organ. The disease mainly affects patients on dialysis or patients having undergone renal transplantation. UMLS:C4749793 MONDO:0017217 GARD:0021071 MEDGEN:1664968 Orphanet:280068
