Performance on the Wechsler Intelligence Scale for Children–IV

	Typically Developing (TD)		22q11.2DS Hemizygous MET		22q11.2DS Hemizygous VAL

Full-scale IQ	112.15	8.97	78.86^***	14.65	79.00^***	7.69	34.67	.001

Note—Both 22q11.2DS groups differed from the control group on full-scale IQ scores, verbal comprehension, perceptual reasoning, and processing speed index scores, although they did not statistically differ from each other. F statistics from one-way ANOVAs comparing three groups and p values from post hoc Bonferroni tests comparing each of the two 22q11.2DS groups and the TD group are presented.

p < .06 when compared with the TD group.
