Studies suggest that APOA5 variants affect not only total TG concentrations but also the entire lipoprotein subclass distribution, shifting them toward atherogenic dyslipidemia in high-risk subjects.
In conclusion, polymorphisms in genes associated to the development of atherogenic dyslipidemia, especially variants in APOA5 gene (rs3135506 and rs662799), can influence the circulating CD4 T-cell levels in chronically HIV-infected patients.
We analyzed allelic variants of USF1 and APOA5 in families (n=516) ascertained for atherogenic dyslipidemia and in an autopsy series of middle-aged men (n=300) with precise quantitative measurements of atherosclerotic lesions.
