Genome-Wide Association Study Reveals Multiple Loci Associated with Primary Tooth Development during Infancy

Figure 3

The combined impact of the delayed tooth eruption alleles in 5 identified loci at P<5×10−8 in the NFBC1966.

Subjects are classified by the number of delayed tooth eruption alleles. SNPs are chosen so that they had the strongest signal for number of teeth at each locus. Mean time of first tooth eruption is plotted in red and number of teeth by the age of one year in black. The bars represent the number of individuals for each count of ‘delayed tooth eruption’ alleles. The line through points is a linear regression fit.
