Lipoprotein Lipase/Apolipoprotein Cll Gene Polymorphism in Kurdish Patients With Severe Hypertriglyceridemia.

Background Polymorphisms in the  () and  genes have been linked to severe hypertriglyceridemia in several populations. This study investigated the frequency of Hind lllandAva ll polymorphism among Kurdish patients with severe hypertriglyceridemia. Methodology We investigated Hind llland -Ava ll gene polymorphism in a sample of Kurdish patients receiving treatment at Azadi Teaching Hospital in Duhok, Kurdistan Region, Iraq. We included a total of 100 subjects in this study, of which 64 had severe hypertriglyceridemia, and 36 had normotriglyceridemia. There were 56 males and 44 females. We used the polymerase chain reaction-restriction fragment length polymorphism technique to determine the polymorphism of the Hind lll and Ava ll genes. Results In those with severe hypertriglyceridemia, the most frequent alleles were H+H+ Hind lll polymorphism (42, 65.6%) followed by A1A1 Ava ll polymorphism (30, 46.9%), whereas these frequencies were 16 (44.4%) and 6 (16.7%) in those with normotriglyceridemia, respectively. The H+H+ genotype group had considerably higher triglyceride levels and lower high-density lipoprotein cholesterol levels compared with the H-H- genotype group. A similar pattern was observed when comparing the A1A1 and A2A2 genotype groups, with both patterns being statistically significant. Conclusions Our results showed a high frequency of H+H+ Hind III polymorphism in those with hypertriglyceridemia, which may be a hereditary indicator of vulnerability to this condition in the Kurdish population.
