The study focused on so-called coding genetic variants, i.e. variants that are known to change the protein product of the gene. The results of the study, published in Nature on January 18, 2023, ...

Understanding the consequences of genotype for phenotype (which ranges from molecule-level effects to whole-organism traits) is at the core of genetic diagnostics in medicine. Many measures of the ...

A major mouse study found that some inherited traits are passed down through epigenetic changes that break the classic rules of genetics. Researchers discovered hundreds of cases where these chemical ...

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 ...

Parents pass their genes down to their kids, with a child inheriting about 50% of their genome from each parent. But there is another kind of genetic code known as the epigenome that can also be ...

From your eye color to your health risks, genetic inheritance plays a powerful role in who you are. Understanding dominant, recessive, and X-linked traits can help you make sense of family patterns ...

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 ...

Most people with ALS don’t have a family history of it. Still, some cases of ALS are linked to inheriting specific gene mutations. Even nonfamilial cases can be linked to sporadic gene mutations that ...

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 ...
