Three studies identify unintended consequences of gene editing in human embryos, including large deletions and reshuffling of DNA.

In a genome-wide association study, variants in both the ABO blood group locus and a cluster of genes on human chromosome 3 are more common among COVID-19 patients with respiratory failure than in the general population.

Eight amino acids are identical to part of the human epithelial sodium channel, leading researchers to suspect the virus might interfere with the channel’s function.

Once considered an unimportant curiosity, Z-DNA is now recognized to provide an on-the-fly mechanism to regulate how an RNA transcript is edited.

When the nucleic acid spirals to the left, it takes on a zig-zag shape known as Z-DNA that appears to regulate RNA editing.

Wing development in females is environmentally controlled, but in males, an insertion on the sex chromosome appears to dictate whether the insects grow wings, according to a study.

A modeling study counters initial interpretations that the cluster began with someone who flew to Seattle in mid-January.

Two copies of the APOE4 variant, which confers a higher risk of dementia, doubles the risk of severe symptoms as a result of infection with SARS-CoV-2, according to a study.

A large twin study in Sweden finds genetics has a much larger influence on the odds of an autism diagnosis, and has remained consistent over time.
