  • Title: The D9N, N291S and S447X variants in the lipoprotein lipase (LPL) gene are not associated with Type III hyperlipidemia.
    Author: Evans D, Beil FU.
    Journal: BMC Med Genet; 2007 Aug 29; 8():56. PubMed ID: 17727701.
    Abstract:
    BACKGROUND: Type III hyperlipidemia (Type III HLP) is associated with homozygosity for the epsilon2 allele of the APOE gene. However only about 10% of epsilon2 homozygotes develop Type III HLP and it is assumed that additional genetic and/or environmental factors are required for its development. Common variants in the LPL gene have been proposed as likely genetic co-factors. METHODS: The frequency of the LPL SNPs D9N, N291S and S447X in 100 patients with hyperlipidemia and APOE2/2 genotype has been determined and compared to that in healthy blood donors and patients with hyperlipidemia. RESULTS: There were no statistically significant difference in the frequencies of the variants between APOE2/2 patients and controls. CONCLUSION: It is unlikely that the D9N, N291S or S447X variants in the LPL gene play an important role in the development of Type III HLP.
