Chronic obstructive pulmonary disease (COPD) is a deadly and highly morbid disease. Genetic variations play a significant role in COPD risk and heterogeneity, with hundreds of genetic variants identified. Further research with larger studies, more ancestral diversity, and improved profiling methods is needed. Integrating genetic data with other omics data and comprehensive COPD phenotypes, as well as understanding the causal mechanisms of genetic risk variants, can inform novel approaches to COPD pathobiology and treatment strategies.
Chronic obstructive pulmonary disease (COPD) is a deadly and highly morbid disease. Susceptibility to and heterogeneity of COPD are incompletely explained by environmental factors such as cigarette smoking. Family-based and population-based studies have shown that a substantial proportion of COPD risk is related to genetic variation. Genetic association studies have identified hundreds of genetic variants that affect risk for COPD, decreased lung function, and other COPD-related traits. These genetic variants are associated with other pulmonary and non-pulmonary traits, demonstrate a genetic basis for at least part of COPD heterogeneity, have a substantial effect on COPD risk in aggregate, implicate early-life events in COPD pathogenesis, and often involve genes not previously suspected to have a role in COPD. Additional progress will require larger genetic studies with more ancestral diversity, improved profiling of rare variants, and better statistical methods. Through integration of genetic data with other omits data and comprehensive COPD phenotypes, as well as functional description of causal mechanisms for genetic risk variants, COPD genetics will continue to inform novel approaches to understanding the pathobiology of COPD and developing new strategies for management and treatment.
