Is the paraoxonase promoter polymorphism ( -107 ) T > C associated with carotid intima-media thickness in Sicilian hypercholesterolemic patients?
In conclusion, our data provided no evidence of a significant association between either PON1 promoter (-107)T>C or coding region, Q192R and L55M, polymorphisms and early carotid atherosclerosis in Sicilian hypercholesterolemic subjects.
Currently available evidence is limited to cross-sectional and retrospective analyses of patients with RBD. Although ascertainment biases and the retrospective nature of the available evidence limits quantitative analyses, the diagnosis of idiopathic RBD portends a risk of greater than 45% for future development of a clinically defined neurodegenerative disease. This finding has significant implications for clinical neurologic and sleep disorder practice and neurodegenerative disease research.
