Effect of long-term exposure to lower low-density lipoprotein cholesterol beginning early in life on the risk of coronary heart disease: a Mendelian randomization analysis. J Am Coll Cardiol. 2012; 60(25):2631-9.)
|
Combination studies with Mendelian randomization in meta-analysis (association of 9 SNPs in six different genes) to obtain the most accurate estimate of long-term effect of exposure to low concentrations of LDL-c, and its relationship with risk of CAD and the comparison with effect of lowered LDL-c by use of statins |
CAD risk reduction between 6-28% was observed in 9 SNPs evaluated. The variation of significance for LDL-c values were from - 16.68 to - 2.63 mg/dL. A log-linear variation between exposure to reduced LDL-c and the risk of CAD was verified. Among the 312,321 participants with different SNPs, a risk reduction of 54.5% (OR: 0.45) was found for each mmol/L or 38.7 mg/dL reduction in LDL-c. For 83,873 participants - score LDL-c in 6 SNPs, risk reduction was 53.2% for CAD. On the other hand, in 26 trials that included 169,138 participants treated with statins, risk reduction for CAD was 24% (OR: 0.44) for each 3 mmol/L or 116 mg/dL reduction in LDL-c |
9 polymorphisms were consistently associated with reduced risk of CAD as measured per unit of LDL-c reduction Protective effect is independent of the mechanism of LDL-c reduction What matters is not the reduction method, but the magnitude and duration of exposure to low concentrations of LDL-c A weighted LDL-c genetic score including 13 polymorphisms was associated with 2.13-fold increased risk of MI for each SD (34.1 mg/dL) increase in LDL-c |

|
Assessment of cardiovascular outcomes such as myocardial infarction in populations with genetically high HDL, through Mendelian randomization of SNPs |
Meta-analysis data of 7 cohorts with 19,840 patients of 15 locirelated to high HDL-c plasma levels, 6 associated with reduction of MI but presenting pleiotropic effects of reduction in triglycerides and LDL-c. The remaining SNPs have no association with reduction in MI, and SNP rs16988929 on chromosome 20q13 showed increased risk of MI. In the 20 studies (13 case-control and six cohort studies) with a total of 116,320,000 participants, there was no association between LIPG Asn396Ser and IM risk reduction |
The genetic variant LIPG Asn 396Ser, which raises HDL, did not reduce MI The Score which combined 14 variants related to HDL were not associated with AMI only The data challenge the relation between the increase in HDL and lower risk of AMI The AIM-HIGH trial, which added niacin on statin therapy, showed no lower risk of cardiovascular events, either |

|
Information about metabolic effects derived from the response of the gene involved with different subclasses of lipoproteins of hepatic lipase |
Carriers of the ESR1 PvuII or IVS1-1505 variants had lower plasma TG concentrations and higher plasma HDL-c, alfa1 and pre alfa-1 HDL, apo A-I and alfa-1 levels after hormone therapy than wild-type carriers. Carriers of the N291S and D9N variants in the lipoprotein lipase gene had higher levels of lipoproteins and lower levels of alfa-2 HDL |
Variations in gene lociare involved in the lipid metabolism, as well as subpopulations of TG-rich and HDL lipoproteins. SNPs in ESR1, CETP and LPL had significant effects on baseline plasma levels of these populations. Polymorphisms in genes involved in lipid metabolism do not explain much of the lipid variability and lipoproteic subfractions response to hormone therapy |

|
The effects of G-250A polymorphism in the activity of the hepatic lipase, serum lipid profile, and insulin sensitivity |
The A-250A genotype was associated with high levels of LDL-c (p=0.03 for the 3 genotypes). In the group with monounsaturated fatty acids diet, patients with A-250A genotype showed strong decrease in LDL-c compared to other genotypes (p = 0.007). The -250A allele was associated with low activity of hepatic lipase (p<0.001). The diet did not affect the activity levels of hepatic lipase among the 3 groups |
The A-250A genotype of the hepatic lipase gene was associated with high plasma levels of LDL-c. Nonetheless, those patients who used diets rich in monounsaturated fatty acids showed reductions in serum levels of LDL-c especially in patients with genotype A-250A |

The frequency of homozygous genotypes for the ABCG5 1950>G polymorphism was higher for patients with hypercholesterolemia compared to controls (42 versus 10%, p<0.001). Hypercholesterolemic individuals carrying the GG genotype for 251A > G had higher levels of HDL-c compared to all other genotypes (p=0.02) |
The data show an association between ABCG5 1950 > G polymorphism and hypercholesterolemia. The small size of the sample was a limitation |

|
Predisposing factors for phenotypic characteristics of high total cholesterol (T-Cho) and their association with two variants of APOB48R |
Significant correlation between genotypic variations of A419P and total cholesterol levels was observed. Among the homozygous carriers of the G allele (n=265), heterozygous carriers of the G allele (n=78), and homozygous carriers of the C allele (n=9), total cholesterol levels indicated a co-dominant effect of the C allele of increase in total cholesterol (r=0.15, p=0.007). A similar effect was observed for c.934-960/Del (r=0.13, p=0.015) |

|
Hormone replacement therapy and the progression of atherosclerosis over a follow-up period of 5 years |
A significant association between HRT and genotypes of hepatic lipase was found for increased atherosclerosis severity score (ASC) (p=0.046). In patients with T allele, ASC progression was significantly faster in the control group compared with the HRT (p=0.0006) group, while the CC genotype showed no significant differences |
The results suggest that the beneficial effect of HRT on the progression of atherosclerosis was restricted to women carriers of the T allele |

When compared to homozygotes for the major allele of one of the SNPs, those with a single copy of the minor allele had 22% less reduction in total cholesterol (p =0.01), with an absolute difference of 9.2 mg/dL (95CI 3.8 - 14.6 mg/dL), and 19% less reduction in LDL-c (p=0,005), with an absolute difference of 6.4 mg/dL (95CI 2.2-10.6 g/dL) |
