The COVID-19 pandemic gave us tremendous perspective on how wildly symptoms and outcomes can vary between patients ...

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

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 Finnish population has provided investigators with a rare opportunity. Most Finns descend from a small, so-called founder population of individuals, and people have primarily reproduced with ...

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

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 research, published in Science, argues that the true genetic contribution to the variation in human lifespan has been ...

Genetics can play a role in a person's odds for Alzheimer's disease, and new research suggests differences in that risk are based on which parent had the illness. In a study of 4,400 people still ...

The genotype of an organism is inherited from its parents through the process of reproduction. During sexual reproduction, each parent contributes half of the genetic material to the offspring, ...

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 ...
