Kolkata: In what could help predict one`s susceptibility to various ailments, a new technique to detect genetic variations associated with diseases, including cancer, has been proposed by scientists at the Indian Association for the Cultivation of Science (IACS) here.Some of these genetic variations termed SNPs (pronounced snips) are associated with cancer, certain infectious diseases like leprosy, AIDS, and many others."These genetic variations can give us an idea about how humans respond to pathogens (microorganismic infectious agents like virus, bacterium, prion or fungus that cause diseases), chemicals, drugs, vaccines and other agents," IACS`s associate professor in biological chemistry, Rupa Mukhopadhyay, said.Detection of these genetic variations can help predict one`s susceptibility to diseases. Identification of these abnormalities is often done by using DNA probe based biosensor technologies.DNA is the double stranded helically twisted molecule that serves as the hereditary unit of life.
