Apo B3 Hvr Polymorphism in Healthy Population: Relationships to Serum Lipid Levels
MetadataShow full item record
We have analyzed allele frequency distribution at the hypervariable locus 3 to the apolipoprotein B gene in a healthy population sample (241 women and 246 men) from the Belgrade area. The bimodal distribution of sixteen different hypervariable region (HVR) alleles and the heterozygosity index (average 0.76) in both samples are similar to ones reported for other Caucasian populations. However, we found the hypervariable element containing 34 repeats-HVE34 allele to be the most common one in both female and male samples, and that there was a lower frequency of the HVE GT 36 alleles. For further analysis of 3HVR allele frequency and its possible association with serum lipid levels, all HVR alleles were grouped into five main types (HVE LT 32, HVE32, HVE34, HVE36, and HVE GT 36), and the samples were divided into lipid quartiles. We found that (1) apo B gene 3HVR polymorphism is associated with variation of normal lipid levels in males, (2) HVE32 alleles are associated with decreased serum... levels of total cholesterol, LDL cholesterol, and triglycerides, and (3) HVR genotypes containing HVE34 and HVE36 alleles are associated with elevated serum levels of total cholesterol, low density lipoprotein (LDL) cholesterol, and triglycerides.
