  1. Observed mean FSIQ values of the total population (patients, siblings and controls) with standard deviation (SD) are given in 'carriers' versus the 'non-carriers' in which 'carriers' represent the carriers of the low-frequency allele. P-values are given for the comparison of FSIQ values between genotype groups (carriers and non-carriers) using ANOVA with GEE adjusting for age, gender, ethnicity, family membership, and educational level.
