Association of functional sequence variants of the gene with muscle collagen content in pigs.

This study examined the association between functional sequence variants (FSVs) of () genotypes and collagen content in a Landrace and Jeju native pig (JNP) crossbred population. Four muscles (, , , and ) were used for the analysis of meat collagen content, and the same animals were genotyped for the FSVs of the gene by using PCR-RFLP (polymerase chain reaction-restriction fragment length polymorphism). Three FSVs of genotypes were identified and had genotype frequencies of 0.358, 0.551, and 0.091 for , , and , respectively. animals for the FSVs of the genotypes showed higher collagen content in their ( < 0.001), ( < 0.001), ( < 0.001), and ( < 0.001) than homozygous animals. After the validation of this result in other independent populations, the FSVs of MYH3 genotypes can be a valuable genetic marker for improving collagen content in porcine muscles and can also be applied to increase the amount of collagen for biomedical purposes.
