The MYF5 gene has been reported to be integral to muscle growth and development, and hence it has been considered as a candidate gene for meat selection programs in pig. To ascertain whether there was variation in the porcine MYF5 gene, we have developed a method of PCR-single-strand conformational polymorphism (PCR-SSCP) analysis. In this study, two coding regions of the MYF5 gene were investigated. Four unique SSCP patterns were detected in exon 1 and three patterns were identified in exon 3. Two SNPs detected in exon 1 led to a non-synonymous alanine/proline substitution. A nucleotide change in exon 3 did not affect the amino acid sequence. Five extended haplotypes were observed across the two regions. The variation detected in this study might underpin the development of gene markers for improved muscle growth in pig breeding.
