Single Gene Can Boost IQ By Six Points 199
ananyo (2519492) writes "People are living longer, which is good. But old age often brings a decline in mental faculties and many researchers are looking for ways to slow or halt such decline. One group doing so is led by Dena Dubal of the University of California, San Francisco, and Lennart Mucke of the Gladstone Institutes, also in San Francisco. Dr Dubal and Dr Mucke have been studying the role in aging of klotho, a protein encoded by a gene called KL. A particular version of this gene, KL-VS, promotes longevity. One way it does so is by reducing age-related heart disease. Dr Dubal and Dr Mucke wondered if it might have similar powers over age-related cognitive decline. What they found was startling. KL-VS did not curb decline, but it did boost cognitive faculties regardless of a person's age by the equivalent of about six IQ points. If this result, just published in Cell Reports, is confirmed, KL-VS will be the most important genetic agent of non-pathological variation in intelligence yet discovered."

That is part of what they did. They looked at a group of 718 people, about 20% with the gene. Those with the gene scored, on average, 6 points higher. But they went further. They also inserted the gene into otherwise genetically identical mice, and the mice with the gene did significantly better on a range of cognitive tests.

(1) Intelligence is 80% heritable
Neat. I think you're talking about this stuff. [wikipedia.org] It says researchers have put the heritability of IQ between 0.5 and 0.8. However, Turkheimer (2003) found that for children of low socioeconomic status heritability of IQ falls almost to zero. CITATION, BITCH. [sagepub.com]
See the link to heritability [wikipedia.org]:
Heritability measures the fraction of phenotype variability that can be attributed to genetic variation. This is not the same as saying that this fraction of an individual phenotype is caused by genetics. In addition, heritability can change without any genetic change occurring (e.g. when the environment starts contributing to more variation). A case in point, consider that both genes and environment have the potential to influence intelligence. Heritability could increase if genetic variation increases, causing individuals to show more phenotypic variation (e.g. to show different levels of intelligence). On the other hand, heritability might also increase if the environmental variation decreases, causing individuals to show less phenotypic variation (e.g. to show more similar levels of intelligence). Heritability is increasing because genetics are contributing more variation or because non-genetic factors are contributing less variation; what matters is the relative contribution.
Key point: Heritability goes up and down depending on the environment. The environmental variation is completely dominant for the poor. Go figure, it sucks being poor and it's hard to go get your life on track.
