However, their jumps can also make the genome less stable and create mutations that have been associated with neurodevelopmental disorders, autoimmune disease and cancer.","pubDate":"Tue, 20 Oct 2026 08:40:04 EDT","url":"https://phys.org/news/2026-10-genes-role-protein-complex.html"},"indexado":"2026-10-20T12:40:53.945Z"}}
