Results of haplotypes analyses using SHEsis software regarding the association of APOA1, ABCA1, and LCAT haplotypes and dyslipidemia showed that the A-C-A-C-A haplotype was significantly more frequent in the case group than in the control group, whereas the G-G-G-T-G haplotypes was less frequent in the case group than in the control group. This evidence concerns the gene LCAT and metabolic syndrome.
