The last two genes of the previously described cluster, i.e., IBSP (Integrin Binding Sialoprotein) and MEPE (Matrix Extracellular Phosphoglycoprotein) genes, were identified as potential candidates for milk protein and milk fat percentage in Israeli Holstein [34] and for dystocia and stillbirth in Norwegian Red cattle [35], highlighting the region’s relevance also for fertility traits. Here, IBSP is linked to dystocia.
