N is presented for medication usage. Other medications include neuroleptics, and other drugs known to affect neurological functioning. Chi square indicated no significant group differences in the number of individuals taking medications overall or within each class (all p’s>0.10). FMRP = Fragile X mental retardation protein. Full Scale IQ is based on the Wechsler Abbreviated Scale for Intelligence (age >/=17 years) or the Wechsler Intelligence Scale for Children (age <17 years). Vineland Adaptive Behavior composite standard scores are reported.
