Figure 1. Schematic genomic structure of BMP4 and coordinates of 13 genotyped SNPs.

Figure 1

Three variants (NM_001202.3, NM_130850.2 and NM_130851.2) of the human BMP4 gene are shown in the figure with 4 exons each aligned from left to right. Filled gray and black boxes represent the untranslated and translated exons respectively. All three variants encode an identical protein through translation of exons 3 and 4. Scale on top of the figure shows position of the gene and coordinates for the 13 genotyped SNPs basing on GRCh build 37.3. Minor allele frequency for one SNP (rs2855527) was less than 1% in both Asian and Maryland founders and was excluded from association analysis.
