Variants above gene maps were identified in HTG patients and variants below gene maps were identified in controls. Rare variants are coloured according to their identification in control subjects or previous identification in subjects of unknown clinical status (black), exclusivity to HTG patients or controls (blue), or proven biological dysfunction or truncation (red). Nomenclature refers to functional protein sequences. Only exons 26 and 29 were resequenced in APOB. Gene maps are roughly to scale, although differ in scale between genes. GWAS, genome-wide association study; HTG, hypertriglyceridemia; TG, triglyceride.
