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 ...

Mice show that DNA methylation tags can defy Mendel’s inheritance rules by appearing in offspring even when neither parent ...

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 ...

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 ...

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 ...

A new study suggests that the long-standing Mendelian view of genetics has some blind spots.

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, ...

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 ...

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 ...

Scientific studies to date suggest that autism tends to run in families, and that it develops due to genetic and environmental factors. Recently a team of researchers from Oak Ridge National ...
