In 2002, Pendás et al. and Bergo et al., developed the first HGPS mouse model – Zmpste24-null (Zmpste24−/−) mice – which showed growth retardation, cardiomyopathy, muscular dystrophy, lipodystrophy and premature death (Bergo et al., 2002; Pendas et al., 2002). The gene discussed is ZMPSTE24; the disease is lipodystrophy.
