Returning genomic research findings reveals unrecognized disease risks

A new study published in The American Journal of Human Genetics found that 76.3% of participants who received actionable genomic results were unaware they carried increased risk variants, even though half met clinical criteria for genetic testing. Comprehensive sequencing revealed previously missed variants, emphasizing the need for mo...

Ancient DNA rewrites early Japanese history -- modern day populations have tripartite genetic origin

New study finds that modern Japanese populations have a tripartite genetic origin, with contributions from Jomon hunter-gatherers, Yayoi farmers, and Kofun peoples. The analysis reveals a complex history of population dynamics, including assimilation rather than replacement during the agricultural transition.

Scientists can now assemble entire genomes on their personal computers in minutes

Researchers at MIT and Institut Pasteur have created an efficient method for assembling entire genomes, including the human genome, in minutes using personal computers. This approach uses minimizer-space de Bruijn graphs to store only a small fraction of nucleotides while preserving overall genome structure, enabling faster processing ...

Study of East Africans illuminates new genetic factors underlying human faces

A new study has identified 20 genetic regions linked to face shape in East Africans, highlighting the importance of diverse populations in understanding human facial features. The findings also reveal that shared genetic factors contribute to similarities across populations, while population-specific variants drive differences.

Breakthrough in understanding genesis of fibroids

Researchers at the University of Helsinki have made a significant advance in fibroids research by identifying a new mechanism of tumorigenesis. Multiple tumors carried mutations in genes involved in histone trafficking, which affected gene expression levels and led to hereditary predisposition to the disease.

Cracking one more layer of genetic code will finally enable personalized medicine, researcher says

A McMaster University researcher suggests that understanding biochemical pathways controlling gene expression can unlock the secrets of 'missing heritability' in precision medicine. The study reveals how hidden variations in these pathways contribute to disease development, providing a new approach to personalized care.

Decoding humans' survival from coronaviruses

An international team analysed genomes of over 2,500 humans from 26 populations to understand human adaptation to historical coronavirus outbreaks. They found signs of adaptation in 42 different human genes encoding viral interacting proteins (VIPs), which primarily active in the lungs and interact with coronaviruses.

Viruses: Evolution on the outskirts

Studies on viral evolution reveal that beneficial mutations often occur at the expense of symptom severity, while genetic novelties can arise from noncoding DNA insertion. Additionally, viruses' codon usage is constrained by host machinery, with some exhibiting unique compositions, and their effects can persist after infection clearance.
