Genotype	WBC, ×109/L	PLT, ×1012/L	MPV, fL
Male
Add1+/+	6.6 ± 2.7 (18)	0.98 ± 0.25 (14)	5.8 ± 0.7 (18)
Add1−1	7.8 ± 2.4 (15)	1.19 ± 0.18 (12)*	5.4 ± 0.7 (15)
Female
Add1+/+	7.0 ± 2.6 (23)	0.96 ± 0.17 (12)	6.0 ± 0.6 (21)
Add1−1	7.8 ± 4.7 (10)	1.05 ± 0.16 (10)	5.3 ± 0.5 (10)†

All mice were 4 or more weeks of age. Number in parentheses is sample n. All values X plus or minus SD. Data shown exclude all mice showing any signs of hydrocephalus.

WBC indicates white blood cell count; PLT, platelet count; and MPV, mean platelet volume.

^*P < .05.

^†P < .01 verusus sex-matched control (+/+) mice.
