Input: Question: Are the paraoxonase Leu-Met54 and Gln-Arg191 gene polymorphisms associated with the risk of coronary heart disease?
Answer: The present findings do not strengthen the hypothesis that the paraoxonase gene polymorphisms are independently associated with coronary heart disease indicating that these gene variations are of little usefulness as genetic markers of cardiovascular disease.
Output:
no
