The lipoprotein lipase hindiii polymorphism and the susceptibility to hypertension

الملخص EN

Lipoprotein lipase (LPL) enzyme plays a central role in lipid metabolism.

The primary function of LPL enz yme is the hydrolysis of the core triglycerides of circulating chylomicron and very low density lipoprotein (VLDL).

It releases monoglycerides and free fatty acids, which are tak en up by skeletal muscle or adipose tissue.

The present work aimed to study the association of the common variant of LPL HindIII (H +) and hypertension.

HindIII (+) variant allele of LPL were determined by polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) assa y in 150 hypertensive patients and 150 normotensive as a control group.

Serum lipoproteins were also observed in both groups.

Allele frequencies were H + = 0.733 and H - = 0.267 for LPL HindIII in the hypertension group compared to H + = 0.683 and H - = 0.317 in the control group.

Individuals with homozygous (H + / +) ge notype were at higher risk of developing hypertension compared to the (H - / -) genotype (Odds Ratio OR = 2.13, 95 % Confidence Interval CI = 0.937-4.8).

Serum TG level were also higher in the individuals with (H + / +) genotype compared to the (H - / -) genet ype, while HDL showed negative correlation with the presence of (H + / +) genotype.

It can be concluded that the LPL HindIII (H) variant of LPL may influence the blood lipid metabolism and increase risk for hypertension.
