The acyl-CoA dehydrogenase, C-2 to C-3 short chain (ACADS) gene is known to be related with fat metabolism, especially coverts the fat to the energy sources in cattle. In human, the mutations in this gene cause SCAD deficiency, which is one of the fatty acid metabolism disorders. The ACADS gene is located on bovine chromosome 17. The objective of this study was to identify SNPs in Hanwoo ACADS gene and identify the relationships with economic traits. In this study, two SNPs, T1570G SNP in exon 2 and G13917A SNP in exon 4, were observed. Moreover, in the coding region, 2 missense mutations, T (Cys) ${ ightarrow}$ G (Trp) mutation at 1570 bp and G (Arg) ${ ightarrow}$ A (Gln) mutation at 13917 bp, were observed. These mutations were subjected to the PCR-RFLP for typing 198 Hanwoo animals. The observed genotype frequency for T1570G was 0.135 (TT), 0.860 (TG) and 0.005 (GG), respectively. Also, 0.900 (GG) and 0.100 (GA) were observed for the G13917A mutation. The association of these SNPs with four economic traits, CW (Carcass Weight), BF (Backfat Thickness), LMA (Longissimus Muscle Area), MS (Marbling Score), were also observed. The results indicated that no significant results were observed in all four traits (P>0.05). This might indicate that further studies are ultimately needed to use the SNPs in ACADS gene in lager populations for effectively used for the marker assisted selection.
