Association of rs2710102–rs759178–rs17236239–rs2538976 haplotypes with a quantitative measure of early communicative behavior

Haplotype*	Frequency†	P value	Factor‡
TTAA	0.48	0.0488	2
CGGG	0.35	0.0627	1
CGAG	0.15	0.0014	2

^*Alleles are given with respect to the forward strand of chromosome 7.

^†Frequency of haplotype within the Raine sample.

^‡Analysis in R assessed two factors: 1 = comparison between harboring two copies and one copy of the haplotype; 2 = comparison between harboring two copies and no copies of the haplotype. This column indicates which factor yielded the most significant result, as reported in the preceding column.
