Gene sequencing revealed a mutation specific to humans that triggers a change in the splicing pattern of the neuropsin gene, creating a new splicing site and a longer protein. Introducing this mutation into chimpanzee DNA resulted in the creation of type II neuropsin. "Hence, the human-specific ...

These alterations account for one-quarter of all disease-causing mutations in humans. When the number of bases involved is not a multiple of three, the reading frame is changed, referred to as a frameshift mutation. Insertions or deletions in the coding region of a gene may alter the ...
Mutationsoccur when the number or order of bases in a gene is disrupted. Nucleotides can be deleted, doubled, rearranged, or replaced, each alteration having a particular effect. Mutation generally has little or no effect, but, when it does alter an organism, the change may be lethal or ca...
The researchers also report that a drug affecting a specific type of nerve function reduced the obsessive behavior in the animals, suggesting a potential way to treat repetitive behaviors in humans. The findings appear in the Feb. 24 issue of theJournal of Neuroscience. ...
This type of gene editing technology is already used every day in fields ranging from agriculture to drug development. The tools enable scientists to alter the DNA of living cells -- from plants, animals, and now, potentially, even humans -- more precisely than ever before. Think of it as...

A gene mutation is defined as changes in single DNA bases or small intragenic deletions and rearrangements that disrupt normal gene function. These mutations can include single base changes, insertions, deletions, or rearrangements within a gene, and are heritable effects typically measured in posttrea...
