Geneticists explore disease control via nurture
The new field of genetics aims to combat diseases by modifying the "above the genome" or epigenome, which is a network of chemical markers that influence gene expression, rather than permanently altering the genes themselves. This approach allows for changing how genes are expressed in response to external factors such as stress, nutrition, and exposure to toxins. It opens up promising possibilities for treating or preventing diseases like hepatitis, asthma, and heart conditions. Epigenome editing is considered safer than CRISPR technology because it seeks to adjust the level of gene expression rather than deleting genes. It is expected to be used soon for treating chronic illnesses, with potential applications later in non-medical areas such as enhancing growth and intelligence, although ethical discussions are ongoing regarding its use outside of medical treatments.
