Figure 1. Schematic of aquaporin-1 (AQP1) and solute carrier family 4, sodium bicarbonate transporter, member 10 (SLC4A10) genes. The locations of the genotyped tagging single nucleotide polymorphisms (SNPs) identified using HaploView software in the AQP1 and SLC4A10 genes are shown in relation to the exons that are depicted as vertical boxes or lines and the introns that are depicted as a horizontal line.
