RT Journal Article SR Electronic T1 Genes for super-intelligence? JF Journal of Medical Genetics JO J Med Genet FD BMJ Publishing Group Ltd SP 410 OP 413 DO 10.1136/jmg.18.6.410 VO 18 IS 6 A1 J A Sofaer A1 A E Emery YR 1981 UL http://jmg.bmj.com/content/18/6/410.abstract AB The results of a postal questionnaire distributed to British members of Mensa failed to confirm an association of superior intelligence with torsion dystonia, retinoblastoma, or phenylketonuria, but were consistent with real associations between high IQ and infantile autism, gout, and myopia. Further confirmation of these findings in other populations might well indicate that genes producing these disorders have more or less direct effects on cerebral development and function.
