Abstract

Carbamoyl phosphate synthase 1 (CPS1) is a key gene in the first step of urea cycle. A functional single nucleotide polymorphism C/A has been reported to be associated with high levels of homocysteine. Increase in the homocysteine levels result to increase in hypertension most especially among the aged. This study, thus investigated the association of CPS1 (rs1047891) with primary hypertension with reference to a global simulated data.

A total of 100 participants, 50 normotensives were matched with 50 hypertensives within 18-80 years of age in Ibadan, South-west Nigeria were studied. A total of 2000 simulated global data set was used having 382 as normotensives and 1618 as hypertensives. Blood samples of participants from Ibadan were taken and other clinical parameters such as age, sex weight, height, systolic blood pressure and diastolic blood pressure were determined. The participants were genotyped for one SNP variant (rs1047891) using polymerase chain reaction and enzymatic restriction. Statistical analysis was performed using Haploview 4.2, Plink and SPSS ® 20.0 software for windows and p-value set at p<0.05.

The minor allele frequency of rs1047891 of CPS1 gene was similar to that in the hapmap database among the Yoruba population. The distribution of rs1047891 of CPS1 gene and n4_3, n4_4, m4_0 and qr2_4 of the simulated global data set genotypes was consistent with the Hardy-Weinberg equilibrium (P>0.05). There was no statistically significant association (p>0.05) between the polymorphism of CPS1 gene and SNPs in the simulated global data set with hypertension.
