<i>AGXT2</i> SNPs and biochemical measures.

Median values (25–75% percentile) are shown. The Kruskal-Wallis test was used for statistical analysis. * Plasma concentrations of methylarginines, BAIB and L-arginine were determined for 395 volunteers. †Serum concentrations of creatinine were determined for 390 volunteers. ‡Cockgroft-Gault formula was used for calculation of creatinine clearance. ADMA, asymmetric dimethylarginine; AGXT2, alanine-glyoxylate aminotransferase 2; BAIB, β-aminoisobutyrate; Hetero, heterozygous for minor allele; Homo, homozygous for minor allele; SDMA, symmetric dimethylarginine; WT (wild-type), homozygous for major allele.
