A patient with pleuroparenchymal fibroelastosis carrying a novel fibrillin-2 gene variant

Abstract

Pleuroparenchymal fibroelastosis is a recently recognized clinical entity characterized by interstitial pneumonia with proliferating elastin in the upper lung regions. Pleuroparenchymal fibroelastosis is categorized as idiopathic or reported depending on the coexistent initiating factors; however, congenital contractural arachnodactyly, which is caused by abnormal production of elastin based on a mutation in the fibrillin-2 gene, is rarely reported with lung lesion resembling pleuroparenchymal fibroelastosis. We present a case of pleuroparenchymal fibroelastosis in a patient with a novel mutation in the fibrillin-2 gene, which encodes the prenatal fibrillin-2 protein as a scaffold for elastin.
