Disease IDSourceNameDescription
265120 OMIMPulmonary surfactant metabolism dysfunction 1 (SMDP1)A rare lung disorder due to impaired surfactant homeostasis. It is characterized by alveolar filling with floccular material that stains positive using the periodic acid-Schiff method and is derived from surfactant phospholipids and protein components. Excessive lipoproteins accumulation in the alveoli results in severe respiratory distress. The disease is caused by variants affecting the gene represented in this entry.
267450 OMIMRespiratory distress syndrome in premature infants (RDS)A lung disease affecting usually premature newborn infants. It is characterized by deficient gas exchange, diffuse atelectasis, high-permeability lung edema and fibrin-rich alveolar deposits called 'hyaline membranes'. Disease susceptibility may be associated with variants affecting the gene represented in this entry. A variation Ile to Thr at position 131 influences the association between specific alleles of SFTPA1 and respiratory distress syndrome in premature infants.
