Abstract
OBJECTIVE
The aim of our study was to investigate the relationship between the rs74434454 polymorphism of the CER1 gene and selected biochemical, densitometric and anthropometric markers in Slovak postmenopausal women of two ethnic groups: Roma and non-Roma.
SUBJECTS AND METHODS
The scientific study included 303 postmenopausal women of the non-Roma and Roma populations who were divided into two groups based on densitometric measurements: control group (CG) and osteoporotic group (OG). Genomic DNA was isolated from peripheral blood using a commercial NucleoSpin® Blood kit following a standard protocol. The TaqMan Real-Time PCR method was used for genotyping. Biochemical markers were measured with Cobas e411 and Cobas Integra400 plus analysers.
RESULTS
In the control group of postmenopausal Roma women, the occurrence of the risk genotype GG was not observed. In the group of Roma women with osteopenia and osteoporosis, the GG genotype occurred at a frequency of 3.03%. In the group of non-Roma women (between CG and OG) statistically significant differences were found in all monitored biochemical markers except CTx-I (p<0.66). In contrast, in the group of Roma women, statistical significance was only found in the osteoresorption marker CTx-I (p<0.007). In the population of Roma women, we did not find a statistically significant difference between the AA, AG and GG genotypes in any of the monitored markers.
CONCLUSIONS
The results provide the first and unique insight on the distribution of genotypes and alleles of the rs74434454 CER1 gene polymorphism and its relationship to markers of bone metabolism in two ethnically distinct groups.
