Table 3. Increased phase delay in response to a brief pulse of light at CT 16 in Q175 mutants.

	WT	Q175 Het	Q175 Hom
	n = 8	n = 7	n = 8
Phase delay (min)
3 months	113±5	118±6	119±4
6 months	120±5	111±4	103±6
9 months	110±2	103±2	120±12
12 months	119±5	104±2	213±24*∧

Data were analyzed using one way ANOVA within an age group. * indicates that post hoc Bonferroni’s t-tests detected significant differences compared to WT, and ^∧ indicates significant differences were detected between Het and Hom groups.
