Some genes are beneficial and enhance longevity. For example, the gene that helps a person metabolize cholesterol would reduce a person's risk of heart disease. Some gene mutations are inherited.

Each gene tells a cell to make a specific molecule, but this isn't performed by the DNA itself. Instead, the information is relayed to cellular machinery by a molecule called messenger RNA.

Gene regulation refers to the mechanisms that act to induce or repress the expression of a gene. These include structural and chemical changes to the genetic material, binding of proteins to ...

New work by Columbia researchers has turned a textbook principle of genetics on its head and revealed why some people who carry disease-causing genes experience no symptoms. Every biology student ...

Variants were classified according to American College of Medical Genetics (ACMG) criteria (Richards et al., 2015). The SYNJ1 gene’s product is key in synaptic vesicle dynamics, with mutations known ...

Among them, SCN1A and MECP2 are responsible for most of the phenotypes associated with these ... Finally, in clinical work, it is highly desirable to perform ASD screening for children with epilepsy ...
