Hemispheric Module-Specific Influence of the X Chromosome on White Matter Connectivity: Evidence from Girls with Turner Syndrome.
Novel insights are provided into the functional pathways in the brain that are regulated by the X chromosome and a module-specific genetic contribution to WM connectivity in the human brain is highlighted.

The delightful letter by Turner and Partington' proposed that (1) genes associated with non-specific mental retardation determine human intelligence, (2) they are located primarily on the X
X-linked mental retardation
The calculated incidence of X-linked forms of mental retardation appeared to account for most of the male excess found in the survey and suggests that 1 in every 5 of the mentally retarded boys in the IQ range in this survey may be retarded on the basis of genes on the X chromosome.
Sources of human psychological differences: the Minnesota Study of Twins Reared Apart.
Evidence for the strong heritability of most psychological traits, sensibly construed, does not detract from the value or importance of parenting, education, and other propaedeutic interventions.
Non-specific X linked mental retardation.
A classification based on genetic localisation and a set of minimal clinical features that should be recorded in the hope of identifying possible specific phenotypes of non-specific X linked mental retardation are proposed.
Prevalence of fragile X syndrome.
The much-quoted prevalence figure of 1:1,000 males for fragile X syndrome is an overestimate in a mixed ethnic population. A reexamination of the individuals from whom those data were derived using
