There were no significant correlations of risk factors (smoking, coronary artery disease, elevated cholesterol, diabetes, obesity, hypertension and family history of genetic disorders) or clinical characteristics with Lp-PLA2 serum levels or tissue Lp-PLA2 grade ≥1 (Tables 1 and 2) or with C. pneumoniae infection as defined by qRT-PCR or IHC as described previously [18], [19] (Tables 3 and 4). Here, PLA2G7 is linked to obesity due to melanocortin 4 receptor deficiency.
