Background: Fatty acid desaturase 1 (FADS1) gene controls the fatty acid metabolism pathway in the human body (Sergeant et al., 2012). Single nucleotide polymorphism (SNP) in FADS1 gene and percentage of polyunsaturated fatty acids inserum lipids was associated (Klingel et al., 2018). Genetically predisposition to higher plasma arachidonic and stearic acid levels were associated with incidence oflarge-artery stroke and venous thromboembolism (Yuan et al., 2019).
Methods: Samples obtained in the COPAT project (Childhood Obesity Prevalence And Treatment) were used. Genomic DNA was extracted from peripheral blood leucocytes in whole blood samples. For genotype analysis TaqPath (LC480, Roche) was used. Sample of 754 adolescents (376 girls and 378 boys) from the Czech Republic was examinated in this project. Association of SNPs with fatty acid composition was conducted using the SIMCA-P12 (Umetrics, Umea, Sweden).
Results: The relationship of the risk allele (rs174537) with 12 fatty acids was significant. In SNP (rs 174537) has been relationship between risk allele and two fatty acids (20:4 n-6; 18:3 n-6) in all three lipid classes.
Conclusion: Single nucleotide polymorphisms (rs174537) in FADS1 gene had a significant negative relationship with two fatty acids, (20:4 n-6 and 18:3 n-6), in all three lipid classes.
Conflict of Interest: None Disclosed.
