- HLP type 1 defined as children or adolescents with LPL deficiency due to absent post-heparin LPL activity and/or mutated LPL or APOC2 alleles.
- Clinical, biochemical and genetic features of study subjects are shown in Table 2. For all HLP phenotypes, APOA5 S19W and -1131T>C genotype frequencies did not deviate significantly from expectations of the Hardy- Weinberg equilibrium.

Thus, the results indicate that both variants individually have comparably strong associations with HTG and HLP 2B, 3, 4 and 5. Furthermore, given the absence of significant linkage disequilibrium between APOA5 S19W and -1131T>C, the genotypes function effectively as independent determinants of HTG and the essentially independent information that each provides can be combined.

Abstract
Cette invention concerne un procédé permettant d'évaluer le risque d'une hypertriglycéridémie sévère chez un mammifère, lequel procédé consiste à déterminer dans un échantillon contenant des acides nucléiques prélevé sur le mammifère la présence d'au moins un polymorphisme dans le gène APOA5. L'identification d'un polymorphisme APOA5 indiquant un risque d'hypertriglycéridémie sévère.
