The human genome has been fully decoded for the first time, separating the genetic information inherited from each parent, according to a new international study. This achievement, reported in Cell Genomics and Cell, marks a significant milestone in personalized medicine, potentially allowing doctors to trace genetic variations and tailor treatments accordingly.

The study, led by researchers from Johns Hopkins University and the National Human Genome Research Institute (NHGRI), involved sequencing the DNA of a single surviving human individual, HG002, who is the result of a mother and father. Using this reference genome, the research team was able to identify and catalog 9 billion new genetic sequences, representing 15% of the total 60 billion genetic letters.

This new sequencing approach has the potential to uncover new insights into various genetic disorders, including rare diseases affecting children. The study also highlights the importance of reference genomes from other species, such as macaques and mice, in understanding evolutionary processes and potential applications in artificial intelligence for accurate diagnosis and personalized treatment plans.
