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 ...

In “What We Inherit,” Sam Trejo and Daphne O. Martschenko examine the link between genetic myths and social genomics.

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 ...

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

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

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

Dear Readers: For most people, finding out that they have come into an inheritance is a positive experience. Not so when that inheritance is early onset familial Alzheimer's disease (eFAD). This type ...

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 ...

Neurofibromatosis type 2 is caused by a change in the NF2 gene located on chromosome 22. This gene encodes a protein known as merlin. Mutations in the NF2 gene disrupt the function of merlin, which is ...

Although schwannomatosis is a genetic condition, the inheritance patterns for this disorder are complex and much less clear than for both NF1 and NF2. Some cases of schwannomatosis are familial, with ...
