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 ...

Evolutionary genetics is the study of how genetic variation leads to evolutionary change. It includes topics such as the evolution of genome structure, the genetic basis of speciation and adaptation, ...

In a recent study published in Nature Genetics, researchers created a comprehensive atlas to elucidate the combined impacts of genetic inheritance and environmental exposures on the human immune ...

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 ...

Blood samples are often used to evaluate gene expression in people. But those samples only provide a snapshot of gene activity at one moment in time. This point has been emphasized by a recent paper ...

In Mendelian inheritance patterns, you receive one version of a gene, called an allele, from each parent. These alleles can be dominant or recessive. Non-Mendelian genetics don’t completely follow ...

A new study from the NIH’s All of Us program is shaking up long-held assumptions by revealing that genetic ancestry rarely aligns with racial labels — and that the interplay between biology and ...

Rett syndrome is a rare developmental disorder, most often due to a mutation in the MECP2 gene on the X chromosome, but it’s not usually inherited. Advances in genetics have launched a new era in ...
