rs5174

rs5174 encodes a variant of the LRP8 gene, encoding the low density lipoprotein receptor-related 8 protein (or the apolipoprotein e receptor). The variant affects the protein, changing an arginine to a glutamine; depending on the publication, it can be referred to by terms like R952Q or Arg952Gln. In three Caucasian populations combined, the odds ratio for coronary artery disease or myocardial infarction (and thus heart disease) is 1.31 (adjusted p=0.0003). Note that this association was only seen in populations with familial and premature disease, as a study of 1,231 patients with primarily late-onset, sporadic heart disease did not show any correlation with this SNP. rs5174 (or its equivalent, rs5177) was analyzed in 1,210 patients with familial MI and 1,015 controls from the German MI Family study, in 1,926 familial CAD (1,377 with MI) patients and 2,938 controls from the Wellcome Trust Case Control Consortium (WTCCC) MI/CAD cohort, in 346 CAD patients and 351 controls from the AtheroGene study and in 295 men with incident CAD and 301 controls from the Prospective Epidemiological Study of MI study; no evidence was found for association in any of the populations studied.
