Discovery of SNP in exon 14 of the ADD1 gene and its association with fatness traits in four meat-type duck populations (Brief Report)

Fatness traits are important economically traits in meat producing animals including duck (WU et al. 2008a, b). In human, the α-Adducin (ADD1) gene polymorphism was associated with blood pressure and other subsequent negative effects related to obesity, cardiovascular and renal failure. In fact, there was some relationship between obesity and hypertension. Thus the ADD1 gene is a candidate gene for fatness traits and the study aims to invest the relationship between the polymorphism of the ADD1 gene and fatness and growth traits.
