Polymorphisms in the regulatory region of the porcine MYLPF gene are related to meat quality traits in the Large White breed

The MYLPF gene encodes fast myosin regulatory light chain, and is a positional and functional candidate gene for meat quality. The aim of this study was to identify associations between SNPs in the promoter region of the porcine MYLPF gene and meat quality traits. A total of 22 SNPs were identified...

Description
Summary:The MYLPF gene encodes fast myosin regulatory light chain, and is a positional and functional candidate gene for meat quality. The aim of this study was to identify associations between SNPs in the promoter region of the porcine MYLPF gene and meat quality traits. A total of 22 SNPs were identified in a population of crossbred animals (n=86) and based on minor allele frequency and proximity to the transcription start site, five SNPs were genotyped in purebred; Large White (n=98), Duroc (n=99) and Pietrain (n=98) pigs. No associations were observed in the Pietrain breed, while the Duroc breed was almost monomorphic for all SNPs. In the Large White breed SNP g-1314A>G and linked SNPS g.-871T>G, g.-566T>C, g.-403C>G were associated with ultimate pH and driploss (P
