Males with XYY chromosomes are often taller than average and may have mild mental impairment. Turner syndrome is associated with short stature and typically affects females. Down syndrome is characterized by intellectual disability, but is not necessarily linked to height. XXY chromosomes are associated with Klinefelter syndrome, which can cause tall stature, but typically also results in more severe intellectual disability than what is described in the question prompt.
