Capture Sequencing to Explore and Map Rare Casein Variants in Goats.

Genetic variations in the four casein genes , , , and have obtained substantial attention since they affect the milk protein yield, milk composition, cheese processing properties, and digestibility as well as tolerance in human nutrition. Furthermore, milk protein variants are used for breed characterization, biodiversity, and phylogenetic studies. The current study aimed at the identification of casein protein variants in five domestic goat breeds from Sudan (Nubian, Desert, Nilotic, Taggar, and Saanen) and three wild goat species [ (Bezoar ibex), (Nubian ibex), and (Alpine ibex)].
