Regulatory activity of RE1 for the 3 major human haplotypes in vitro. A, Genome browser view from the human RE1 region (ie, chr3:55,605,229-55,607,027; GRCh37), depicting the location and characteristics of the single nucleotide polymorphisms (SNPs) within RE1 and the 3 major haplotypes. Provided r2 and D-prime are in relationship to the lead SNP rs56219800. B, Luciferase activity were measured in HL1 cells transfected with constructs for RE1 haplotype 1 (n=4), haplotype 2 (n=8), and haplotype 3 (n=4). Values were normalized to the activity of empty pGL4-SCP1-luc. *P=2.6×10−5, **P=2.6×10−6 (1-way ANOVA). C, TBX20 motif sequence as identified by HOMER motif analysis showing rs79492708 abolishes a TBX20-binding site.
