Table 4. Overlap of GWAS signals for birth weight GWAS and childhood obesity GWAS.

GWAS P value threshold	Overlap OR	Number of overlap SNPs	N of overlap SNPs consistent risk allele	% SNPs with consistent risk allele	p-value of risk allele consistent
1.0E-03	1.55	36	33	91	3.52E-07
1.0E-02	1.77	1062	713	67	7.07E-29

P value threshold; GWAS p value threshold applied to both birth weight GWAS and childhood obesity GWAS. Consistent direction allele; the SNPs where the same allele association with higher birth weight and higher child obesity.
