Analysis of both determined AGXT2 SNPs with regard to plasma (in µmol/L) and urinary (in µmol/g creatinine) BAIB concentrations.

Median values (25–75% percentile) are shown. Both SNPs were significant for plasma and urinary BAIB in two-way ANOVA models using log-transformed data. The p values in the last rows and lower columns are based on nested ANOVA tests of log-transformed data (significant if pAGXT2, alanine-glyoxylate aminotransferase 2; BAIB, β-aminoisobutyrate; Hetero, heterozygous for minor allele; Homo, homozygous for minor allele; n.d., not determined; WT (wild-type), homozygous for major allele.
