Gene hunt is on for mental disability : Nature News | Philosophy and Science of Mind and Brain |
It turns out that there’s a class of mental disability found in children that isn’t attributable to the common genetic abnormalities, and also don’t have an environmental component as with fetal alcohol syndrome for instance. It is the hope of the researchers that by sequencing the exomes (translated gene regions) of these children, and by comparing them with their parents’, the mutations that are most likely responsible for their intellectual disability will pop out. Perhaps they’ll find single gene mutations of interest, but I’m not too optimistic about that.
