Several studies have reported associations between κ-casein (κ-CN) genetic variants A and B and milk composition and properties (for review, see Ng-Kwai- Hang, 1998). For instance, genetic variant κ-CN B was associated with higher protein, casein and κ-CN contents. The objective of the present study was to demonstrate a differential expression of κ-CN genetic variants A and B at the mRNA level in mammary epithelial cells during lactation.
