title: DNA sequence of the porcine alpha-lactalbumin 5' flanking region and single-base polymorphisms within this region.
abstract: The 5' flanking region of the alpha-lactalbumin (alpha-LA) gene was sequenced for the Duroc, Yorkshire and Meishan breeds of swine to identify potential sequence variants within this regulatory region of the porcine alpha-LA gene. The sequenced region of the gene encompasses 391bp5' of the translation start site to 11bp3' of the translation start site. Within this sequence of the porcine alpha-LA gene two single-base pair differences were detected. One variant occurs at position -178 and the other at position -235 from the translation start site. Each of the variations can be detected by a restriction fragment length polymorphism within a polymerase chain reaction amplified product. The polymorphisms at the -178 and -235 positions appear to be genetically linked in the animals that have been analysed.
