Description : Surfactant protein C (SPC) deficiency is a rare autosomal dominant disease associated
with progressive respiratory insufficiency and lung disease with a variable clinical
course. The pathophysiology of the disorder is postulated to involve intracellular
accumulation of a structurally defective SPC protein (Thomas et al., 2002). For a
general phenotypic description and a discussion of genetic heterogeneity of pulmonary
surfactant metabolism dysfunction, see SMDP1 (265120).;
Inheritance : Autosomal dominant;
Molecular basis : Caused by mutation in the surfactant pulmonary-associated protein C gene (SFTPC, 178620.0001);
