How much of our lifespan is written in our genes, and how much is sitting on our plates? A new analysis suggests that while genetics matter, everyday dietary choices may matter more. The message: ...

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 ...

I recently underwent genetic testing to see if I had any mutations that could be associated with an increased cancer risk. When I received my genetic testing kit in the mail, I quickly opened the ...

How big of a role do our genes play in our lifespan? Quite a bit more than previously thought, a new study suggests.

The Y chromosome is inherited only through the paternal line. Sons receive their Y chromosome exclusively from their father.

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 ...

Gregor Mendel described his experiments with pea plants and proved that genes are transmitted in discrete units, with certain ...

Modern research shows height is shaped by both nature and nurture. Genes establish a framework, while the environment determines expression. Neither factor works in isolation. Accepting this ...

Medically reviewed by Kiarra King, MD Endometriosis can run in families, but it is not inherited from a single gene. Having a close relative with endometriosis increases your risk of developing the ...

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 ...

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 ...
