Associations of the apolipoprotein A1/C3/A4/A5 gene cluster with triglyceride and HDL cholesterol levels in women with type 2 diabetes

Abstract

The apolipoprotein gene cluster (APOA1/C3/A4/A5) was recently associated with triglycerides (TG) and high-density lipoprotein cholesterol (HDL-C) in non-diabetic population. Little is known whether the variations in these genes affect lipid homeostasis in patients with type 2 diabetes. We examined the associations of 10 polymorphisms at APOA1/C3/A4/A5 gene cluster with blood lipids among 902 diabetic women. A linkage disequilibrium (LD) breakdown was observed between APOA5 and other genes. APOA5 S19W was associated with significantly higher fasting TG levels (P=0.001). Two common haplotypes encompassing four APOA5 polymorphisms (SNP1, SNP2, S19W, and SNP3) were associated with 35.6 mg/dL (haplotype 2212, APOA5*2, P=0.016) and 57.8 mg/dL (haplotype 1121, APOA5*3, P=0.0002) higher fasting TG levels compared with the most common (haplotype 1111, APOA5*1), respectively. Adjustment for age, BMI, and other covariates did not appreciably change such associations. In addition, APOC3 promoter polymorphism -455T/C showed significant associations with fasting TG levels (P=0.006), whereas APOA4 +347T/A showed significant associations with lower levels of HDL-C (P=0.017). Our results indicate that the variability in APOA1/C3/A4/A5 gene cluster may affect TG and HDL levels in women with type 2 diabetes.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • A meta p-value of 2.7×10−10 for rs3135506 reported by Willer et al. in 8,684 subjects, and a meta p-value of 2.4×10−15 for 3,248 subjects in association with triglycerides, represent supportive replication evidence.

    “Hence, a meta p-value of 2.7×10−10 for the same polymorphism reported by Willer et al. [99] in a sample of 8,684 subjects, and a meta p-value of 2.4×10−15 for a sample of 3,248 subjects in association with TG represent a supportive replication evidence.”

  • The minor allele of rs3135506 (minor allele frequency about 6% in whites) has been repeatedly associated with increased plasma triglyceride concentrations.

    “The minor allele of rs3135506 (minor allele frequency (MAF) of about 6% in whites) has been repeatedly associated with increased plasma TG concentrations [96–99].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
