BACKGROUND: The importance of apolipoprotein A-V (APOAV) gene variants in the determination of plasma triglyceride levels in humans has been proven in several population studies. OBJECTIVES: To investigate whether APOAV gene variants are associated with the different plasma cholesterol fractions. METHODS: The influence of APOAV polymorphisms (T-1131>C, Ser19>Trp and Val153>Met) on plasma cholesterol fractions was evaluated in 1191 men and 1368 women representatively selected from the Czech population. Low-density lipoprotein cholesterol, non-high-density lipoprotein (non-HDL) cholesterol and HDL cholesterol levels were analyzed. RESULTS: The T-1131>C variation in the APOAV gene was found to affect plasma non-HDL cholesterol, showing significantly higher levels in C-1131 carriers than in T/T-1131 homozygotes. This association was observed in both men (4.61+/-1.09 mmol/L in C-1131 carriers versus 4.47+/-1.07 mmol/L in T/T-1131 homozygotes; P<0.01) and women (4.46+/-1.22 mmol/L in C-1131 carriers versus 4.24+/-1.17 mmol/L in T/T-1131 homozygotes; P<0.01). Interestingly, when low-density lipoprotein cholesterol (obtained by the Friedewald formula) or HDL cholesterol levels were analyzed, no significant association was detected. CONCLUSION: The APOAV gene variant T-1131>C may play a role not just in the genetic determination of triglyceride levels but may also influence plasma levels of non-HDL cholesterol.

The important role of APOAV gene T-1131>C variant in determination of plasma triglyceride levels has been proved on many population studies. Recently, associations between C-1131 allele and higher mother's height as well as with longer fetal birth length were suggested. In 1,305 females, aged between 28 and 67 years and having at least one child, we have analyzed a putative association between T-1131>C APOAV variant (analyzed by PCR and restriction analysis) and body height. Mother's body height did not differ between T/T homozygotes (N = 1093, 162.5 +/- 6.5 cm) and C allele carriers (N = 212, 162.1 +/- 6.4 cm). Thus we have failed to confirm, that mothers with APOAV C-1131 allele are higher than T/T-1131 homozygotes.
