B) Allelic distribution comparing GG vs TT (x-axis) for the peak SNP of the Pex16 association (rs27364570), where the abundance of each LPC species (y-axis) showed significantly different levels depending on the allele. P-values for GWAS associations were calculated using FaST-LMM. Boxplots show mean (middle line), 25-75% quantiles (colored box) and 5-95% quantiles (vertical lines)
