Association of a syndrome resembling Wegener's granulomatosis with low surface expression of HLA class-I molecules

Abstract

Background Granulomatous syndromes, such as Wegener's granulomatosis, are defined according to complex criteria, but the underlying cause is rarely identified. We present evidence for a new aetiology for chronic granulomatous lesions associated with a recessive genetic defect, which is linked to the human leucocyte antigen (HLA) locus.
