redundancy of the human genome

Posted by & filed under _.

Genome-sequencing studies indicate that all humans carry multiple genetic variants predicted to cause loss of function (LoF) of protein-coding genes. McArthur et al. estimated that human genomes contain ~100 genuine LoF variants with ~20 genes completely inactivated. They also described a method for using the differences found between LoF-tolerant and recessive disease genes to prioritize candidate genes found in clinical sequencing studies. This study suggests that the human genome is more redundant than previously thought.
