Fatty acid composition of meat is becoming more important due to consumer demand for high quality and healthy foods. The present study evaluated the associations of five candidate genes (FABP4, FASN, NR1H3, GH and SCD) with fatty acid composition in Korean cattle (Hanwoo). The g.3691G > A single nucleotide polymorphism (SNP) in the FABP4 gene had significant effects on high myristic acid (C14:0; P < 0.01) and palmitic (C16:0; P < 0.05) in animals having the GG genotype, and high arachidonic acid (C20:4; P < 0.05) in the AA genotype of Hanwoo. The FASN SNP at position g.17924G > A was also significantly associated with myristic acid (P < 0.01). In case of the SCD gene, a significant effect was only observed in myristoleic acid (C14:1; P < 0.01). However, SNPs in GH and NR1H3 genes showed no effects on fatty acid composition. The results indicate that SNPs in three candidate genes, FABP4, FASN and SCD, may be influential in breeding design for fatty acid composition in Hanwoo.
