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 advanced test analyses a cow’s beta casein gene for the seven main variants known to occur in cattle: A1, A2, A3, B, C, I and H2.


Chromosome: 6

Gene: CSN2

Mode of Inheritance: Autosomal Co-Dominant

Organ: Endocrine System

Sub-organ: Mammary glands


Year published: 2013

Clinical Features

Cows will produce milk containing the a mixture of the beta casein variants they carry. For example, a cow genotyped as A2/A2 will produce pure A2 milk, and a cow genotyped as A1/A2 will produce A1 and A2 beta casein.
