Apolipoprotein E and atherosclerosis in Greenland Inuit

Atherosclerosis
D A BoudreauE Jul

Abstract

Arterial, liver, and serum specimens were collected from Greenland Inuit at autopsy and apolipoprotein E genotyping was done on 42 females (mean age = 61.3 years) and 56 males (mean age = 56.8 years). Estimates of the allele frequencies of the apo E, derived from the observed frequencies of the six common apolipoprotein E genotypes, are E2: 0.015+/-0.009; E3: 0.776+/-0.030; and E4: 0.209+/-0.029. No significant difference was found between these frequencies and those previously reported for Greenland Inuit, Canadian Inuit, or Alaska natives; however, differences were observed in comparison with frequencies reported for Japan, Norway, Sweden, USA-Blacks and USA-Whites. Anthropometric data (body mass index, panniculus adiposus thickness), blood analyte levels (total serum cholesterol, HDL-cholesterol, LDL + VLDL-cholesterol, and glycohemoglobin), and prevalence and extent of atherosclerotic lesions in the aorta and coronary arteries were analyzed for any associations with apolipoprotein E genotype. The occurrence of apolipoprotein E2 alleles are very rare and the E4 alleles are slightly more frequent in the Greenland Inuit population as compared to other populations. No significant association between apolipoprotein E genotypes a...Continue Reading

ApoE Phenotypes

Apolipoprotein E (APOE) is a protein involved in fat metabolism and associated with the pathogenesis of Alzheimer's disease and cardiovascular disease. Here is the latest research on APOE phenotypes.

ApoE, Lipids & Cholesterol

Serum cholesterol, triglycerides, apolipoprotein B (APOB)-containing lipoproteins (very low-density lipoprotein (VLDL), immediate-density lipoprotein (IDL), and low-density lipoprotein (LDL), lipoprotein A (LPA)) and the total cholesterol/high-density lipoprotein (HDL) cholesterol ratio are all connected in diseases. Here is the latest research.
