First-ever 'anti-ageing' gene discovered in US' Amish family
US-based researchers have claimed to discover the first genetic mutation that appears to protect against biological ageing in Indiana's Amish community. The mutation, in which the protective cap over chromosomes are 10% longer, significantly lowers incidence of diabetes. The team tested 177 Amish people and found the mutated gene in 43, who also had 10% longer lifespans than the others.
