Figure 8.

BALM morningness-eveningness scores are shown for DSPS cases and their controls. Alleles of rs2482705 (A) and Alleles of rs3828057 (B). BALM scores <28 indicate marked eveningness, e.g., DSPS. Scores ≥28 indicate the normal range or greater morningness. The means (blue circles) and 95% confidence intervals (red bars) are shown for homozygotes with the common alleles (left), heterozygotes (center), and for those uncommon homozygotes with the minor alleles (right). For both SNPs, those with 1 or 2 minor alleles (AG or AA) had BALM means outside the confidence limits for the homozygotes (GG) of the common allele, suggesting that minor alleles were associated with dominant protection from DSPS.
