ZNF146 and Stillbirth: Genes RUN Domain Containing 3B (RUNDC3B; BTA 4), Quinoid Dihydropteridine Reductase (QDPR; BTA 6), Transmembrane Protein 182 (TMEM182; BTA 11), and Zinc Finger Protein (ZFP28; BTA 18) are the closest genes to the retained placenta signals with previous associations related to milk production, productive life, health and reproduction traits, including calving ease and stillbirth [8].
