Turner's syndrome (TS) is a genetic disorder that arises from the complete or partial absence of the second sex chromosome. The T S behavioural phenotype has been
characterised by a specific neuropsychological profile of normal verbal skills, impaired visuo-spatial and/or visuo-perceptual abilities and difficulty with motor function. Recently there have been reports of deficits in executive functions. The current study investigated the role of executive and behavioural functioning in TS females aged 6-16 years.
