A Canadian-led team has identified five genes associated to Type 2 diabetes, by scanning DNA from almost 7,000 individuals.
Dr. Polychronakos says the field is moving so quickly it will soon be possible to predict from birth the ailments to which a particluar person will become prone.
“You’d be able to take a drop of blood from a newborn and determine if they have genes associated with diabetes, or heart disease or Alzheimer’s or any of the common health problems,” said Dr. Polychronakos, acknowledging there would be difficult social and ethical issues associated with such gene profiling.
The researchers are now looking for other genes that increase the susceptibility to Type 2 diabetes, which will help improve diagnoses and treatment.

A Canadian-led team that can decipher an individual’s DNA in just minutes has uncovered several genes that make people susceptible to the most common form of diabetes — and brought researchers a step closer to the controversial possibility of “gene profiling.”
Scientists say they have mapped the most important genes that put people at risk of type 2 diabetes, offering hope that a test could be delivered.
