BTN2A1 and metabolic syndrome: There were some limitations to the present study: i) given that the results of the present study were not replicated, validation of our findings will require their replication with other independent subject panels or ethnic groups; ii) it is possible that rs6929846 of BTN2A1 is in linkage disequilibrium with other polymorphisms in the same gene or in nearby genes that are actually responsible for the development of dyslipidemia or CKD; and iii) the functional relevance of rs6929846 of BTN2A1 to the pathogenesis of dyslipidemia or CKD has not been determined.
