Genetic and environmental factors can have an impact on lung and respiratory disorders which are associated with severe symptoms and have high mortality rates. Many respiratory diseases are significantly influenced by genetic or epigenetic factors. Gene therapy offers a powerful approach providing therapeutic treatment for lung diseases. Clustered regularly interspaced short palindromic repeats (CRISPR) and CRISPR-associated protein 9 (CRISPR/Cas9) are promising gene modifying tool that can edit the genome. The utilization of CRISPR/Cas9 systems in the investigation of respiratory disorders has resulted in advancements such as the rectification of deleterious mutations in patient-derived cells and the alteration of genes in multiple mammalian lung disease models. New avenues of treatment for lung disorders have been opened up by advances in CRISPR/Cas9 research. In this chapter, we discuss the known genes and mutations that cause several common respiratory disorders such as COPD, asthma, IPF, and ARDS. We further review the current research using CRISPR/Cas9 in numerous respiratory disorders and possible therapeutic treatments.

The groundbreaking CRISPR-Cas gene editing method permits exact genetic code alteration. The "CRISPR" DNA protects bacteria from viruses. CRISPR-Cas utilizes a guide RNA to steer the Cas enzyme to the genome's gene editing target. After attaching to a sequence, Cas enzymes cleave DNA to insert, delete, or modify genes. The influence of CRISPR-Cas technology on molecular biology and genetics is profound. It allows for gene function research, animal disease models, and patient genetic therapy. Gene editing has transformed biotechnology, agriculture, and customized medicine. CRISPR-Cas could revolutionize genetics and medicine. CRISPR-Cas may accurately correct genetic flaws that underlie rare diseases, improving their therapy. Gene mutations make CRISPR-Cas gene editing a viable cure for uncommon diseases. We can use CRISPR-Cas to correct genetic abnormalities at the molecular level. This strategy offers hope for remedies and disease understanding. CRISPR-Cas genome editing may enable more targeted and effective treatments for rare medical illnesses with few therapy options. By developing base- and prime-editing CRISPR technology, CRISPR-Cas allows for accurate and efficient genome editing and advanced DNA modification.
