Abstract

Chronic pneumonitis of infancy (CPI) is a rare interstitial lung disease (ILD) that can be fatal in some cases. It occurs in infants who initially appear well and then develop respiratory symptoms with hypoxemia and diffuse interstitial infiltrates (1). Recently, the development of molecular genetic techniques has been rapidly increasing the understanding of the cause of CPI, and mutations in related genes encoding proteins such as surfactant protein (SP)-B, SP-C and ATP-binding cassette protein family A3 (ABCA3) have been identified as a representative cause (2).
