Whole brain monoamines in DD mutant mice

Treatment group	Dopamine	DOPAC	HVA	3MT
Control (n = 10)	63.4 ± 2.4	6.4 ± 0.9	13.8 ± 1.8	11.1 ± 1.6
DD mutants (n = 7)	1.6 ± 0.2^*	ND	1.1 ± 0.1	ND

Results depict average values ± SEM in ng/mg protein.

For dopamine, a 2-tailed t test revealed p < 0.0001. Average HVA values were also low in the DD mice, but a formal statistical comparison was not conducted because 2 of 7 mice had undetectable levels (<1 ng/mg protein). DOPAC and 3MT were not detectable in the DD mice.
