Polymorphism in the gene FABP3 and its association with indicators of meat quality in pigs

Abstract

The objective of this study was to analyze the variability of the FABP3 gene (heart fatty acid-binding protein) in the population of pig Czech large white breed and to analyze the association with parameters of meat quality. FABP3 belongs to multigene family of FABPs (fatty acid binding proteins affecting the transport of long chain fatty acids). Analyzed polymorphism was at position X98558:g.1321 G > C in the 5’ UTR region. The relative frequencies of genotypes were: HH = 0.87and Hh = 0.13. Genotype hh was not detected in the population. The frequencies of alleles were as follows: H = 0.93 and h = 0.07. There were statistically significant associations between genotypes and values of stearic acid and linoleic acid. Highly statistically significant difference was observed with palmitic acid.
