The hydrophobic surfactant proteins, SP-B and SP-C, serve important roles in surfactant function and metabolism. Both proteins are encoded by single genes, located on human chromosomes 2 and 8 respectively, which have been characterized and extensively studied. Mutations in the SP-B gene have been shown to cause severe lung disease, and polymorphisms in the SP-B gene may be associated with the development of RDS in premature infants. In contrast, mutations in the SP-C gene have not yet been identified or shown to cause lung disease, although given the apparent importance of SP-C in surfactant function, this remains a possibility.
