Cow’s milk contains six main proteins that affect its nutritional value: Alpha-casein S1 and S2, beta-casein, kappa-casein, alpha-lactalbumin and beta-lactoglobulin. Various mutations to the genes responsible for forming these proteins can alter its nutritional properties, cheese-making potential, digestibility by human consumers, etc.
This specific test is for a mutation to the beta-lactoglobulin gene PAEP. Beta-lactoglobulin is an important component of milk whey. Increased milk yield and whey protein are associated with high levels of beta-lactoglobulin. The mutation analysed here is responsible for the B allele of beta-lactoglobulin.

Clinical Features
Cows will produce milk containing a mixture of the beta-lactoglobulin variants they carry. For example, a cow genotyped as B/B will produce pure beta-lactoglobulin B, and a cow genotyped as A/B will produce both beta-lactoglobulin A and B in its milk.
