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 ...

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 ...

For more than a century, Mendelian genetics has shaped how we think about inheritance: one gene, one trait. It is a model that still echoes through textbooks—and one that is increasingly reaching its ...

“From Brown to Evergreen: How Eye Colors Evolved” Your eyes may seem ordinary when you catch your reflection each morn ...

How much of our lifespan is written in our genes, and how much is sitting on our plates? A new analysis suggests that while ...

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.

The same pathogen can often elicit very different responses from different people. Scientists sought to understand more about ...

Hypermobile Ehlers–Danlos syndrome (hEDS) is one of the most common heritable connective tissue disorders. Early estimates have reported that this genetic disorder affects at least one in 5,000 ...
