  • Title: Premature centromere division (PCD) identified in a hucul mare with reproductive difficulties.
    Author: Witarski W, Kij B, Nowak A, Bugno-Poniewierska M.
    Journal: Reprod Domest Anim; 2020 Feb; 55(2):248-251. PubMed ID: 31834942.
    Abstract:
    A hucul mare with reproductive abnormalities was examined during karyotype analysis. The karyotype was analysed based on evaluation of 860 metaphase plates in chromosome preparations. The use of fluorescence in situ hybridization (FISH) with an X chromosome painting probe showed premature X chromosome separation in 9.5% cases of examined chromosome spreads. In this report, we present the first identify premature centromere division (PCD) as a possible cause of abnormal X chromosome morphology in horses and as a probable cause of reproductive difficulties.
