The disorder can cause occult alveolar hemorrhage. High-resolution CT imaging of the chest shows patchy centrilobular ground-glass opacities, septal lines, and lymph node enlargement (summary by Eyries et al., 2014).&#13; For a discussion of genetic heterogeneity of pulmonary venoocclusive disease, see PVOD1 (265450).</div>

Individuals with LDS are predisposed to widespread and aggressive arterial aneurysms and pregnancy-related complications including uterine rupture and death. Individuals with LDS can show a strong predisposition for allergic/inflammatory disease including asthma, eczema, and reactions to food or environmental allergens. There is also an increased incidence of gastrointestinal inflammation including eosinophilic esophagitis and gastritis or inflammatory bowel disease. Wide variation in the distribution and severity of clinical features can be seen in individuals with LDS, even among affected individuals within a family who have the same pathogenic variant.</div>
