Scientists have long known that the DNA code in genes is not the only way to pass genetic traits from parents to offspring. "Epigenetic" marks—chemical modifications to DNA that don't change the DNA ...

Research on Tourette’s indicates that the condition is strongly influenced by inherited genetic factors, with environmental factors also contributing to its development. Tourette syndrome is a ...

The blueprint of who we are begins with the genes passed down from our parents. While these inherited traits give us our eye color and height, they can also contain instructions that increase our risk ...

Researchers have identified inherited genetic variants that may predict the loss of one copy of a woman's two X chromosomes as she ages, a phenomenon known as mosaic loss of chromosome X, or mLOX.

Forty years ago, a postdoctoral researcher named James McGrath who would go on to spend more than three decades as a clinical geneticist and research scientist at Yale, made a discovery that advanced ...

The COVID-19 pandemic gave us tremendous perspective on how wildly symptoms and outcomes can vary between patients experiencing the same infection. How can two people infected by the same pathogen ...

From eye color to dimples, the traits that make us unique are rooted in the fascinating science of genetics. Our genes, inherited from both parents, interact in complex ways to determine our physical ...
