Summary

This gene encodes the pulmonary-associated surfactant protein C (SPC), an extremely hydrophobic surfactant protein essential for lung function and homeostasis after birth. Pulmonary surfactant is a surface-active lipoprotein complex composed of 90% lipids and 10% proteins which include plasma proteins and apolipoproteins SPA, SPB, SPC and SPD. The surfactant is secreted by the alveolar cells of the lung and maintains the stability of pulmonary tissue by reducing the surface tension of fluids that coat the lung. Multiple mutations in this gene have been identified, which cause pulmonary surfactant metabolism dysfunction type 2, also called pulmonary alveolar proteinosis due to surfactant protein C deficiency, and are associated with interstitial lung disease in older infants, children, and adults. Alternatively spliced transcript variants encoding different protein isoforms have been identified.[provided by RefSeq, Feb 2010]

Forensic Context

A study in mice demonstrated that hyperoxia exposure significantly downregulated the SFTPC mRNA level, indicating a serious risk for pulmonary collapse and emphysema due to alveolar dysfunction [Shimada et al. DOI:10.1007/S00414-008-0226-6]. In human forensic science, the SFTPC was evaluated as a candidate mRNA marker for lung tissue identification within a multiplex assay designed to infer organ origin from crime scene samples, though it was not selected for the final validated panel [Lindenbergh et al. DOI:10.1007/s00414-013-0895-7]. In nonhuman primates, immunohistochemistry for the SFTPC was used as a type II pneumocyte marker to identify cell types expressing the cell cycle arrest protein p21 in radiation-induced lung injury [Thakur et al. DOI:10.1016/j.ijrobp.2021.03.058].
