A new gene defect has been identified which may predispose people to leukaemia - a condition that could leave many in need of assisted living.
Research published in journal Nature Genetics discovered mutations on the GATA2 gene which predispose individuals to acute myeloid leukaemia and myelodysplasia.
This gene typically functions as a master control during the transition of primitive blood-forming cells into white blood cells.
An international group of scientists collaborated with research on certain families in Australia, Canada and the United States.
They started by studying four families with several cases of acute myeloid leukaemia - a type of blood cancer - which occurred from the teens to the early 40s.
Researchers noted that the inherited error could be more common than they had previously believed.
Meanwhile, research published in the Journal of the National Cancer Institute revealed that the combination of two genes can elevate the risk of lung cancer, particularly in light smokers.
