Genes for Cognitive Function: Developments on the X

Jozef Gécz1,2,4 and John Mulley1,3


Developments in human genome research enabled the first steps toward a
molecular understanding of cognitive function. That there are numerous
genes on the X chromosome affecting intelligence at the lower end of
the cognitive range is no longer in doubt. Naturally occurring
mutations have so far led to the identification of seven genes
accounting for a small proportion of familial nonspecific X-linked
mental retardation. These new data indicate that normal expression of
many more X-linked and autosomal genes contribute to cognitive
function. The emerging knowledge implicating genes in intracellular
signaling pathways provides the insight to identify as candidates
other X-linked and autosomal genes regulating the normal development
of cognitive function. Recent advances in unravelling the underlying
molecular complexity have been spectacular but represent only the
beginning, and new technologies will need to be introduced to complete
the picture.
