LDLR and cardiovascular disorder: As we reported earlier, the low incidence of cardiovascular disease in these patients and the high-risk factor of oxidatively modified LDL (oxLDL) [16] with – in this study – the low level of HDL, high levels of CRP and reduction of LDL receptor expression, lead to the conclusion that in this group of "healthy old" DS subjects, classical biochemical risk factors for atherosclerosis have been detected but risks, probably, are considerably lower.
