There have been only two cases in which a healthy person was known to carry the LMNA mutation that causes progeria. These carriers were identified because they passed it on to their children.[12] One family from India has five children with progeria, though not the classical HGPS type.[44] This family was the subject of a 2005 Bodyshock documentary entitled The 80 Year Old Children. The Vandeweert family of Belgium has two children, Michiel and Amber, with classic HGPS.[45]
