Congenital pulmonary alveolar proteinosis is also known as pulmonary surfactant metabolism dysfunction (SMDP). It is caused by one of the three different genes associated with surfactant metabolism in type II epithelial cells and characterized by respiratory distress after birth. Congenital PAP is also associated with mutations in CSF2RA and CSF2RB genes, encoding alpha and beta chains of the GM-CSF receptor.

A similar but histopathologically distinct disorder of surfactant homeostasis can occur with mutations for the genes encoding surfactant proteins B or C [DS:H00217].
