A novel missense mutation of bovine lipase maturation factor 1 (LMF1) gene and its association with growth traits

Lipase maturation factor 1 (LMF1) gene is a novel candidate gene in severe hypertriglyceridemia. To detect the polymorphism in LMF1 gene in 804 Chinese cattle, we firstly described the polymerase chain reaction-single-strand conformation polymorphism (PCR-SSCP), DNA sequence and PCR-RFLP methods for detecting mutations of LMF1 gene, which affected growth and development in animal. The results...
