Researchers
in Kolkata have discovered what may be a hidden trigger for Down's syndrome,
which could prove crucial in the global fight against the debilitating genetic
disorder. Parents' exposure to arsenic increases the chance of foetus
developing the extra chromosome that causes this incurable disease, they say.
The study was carried out over the last year at Vivekananda Institute of
Medical Sciences (VIMS) in Kolkata by Madhusnata De, professor, VIMS,
Ramakrishna Mission Seva Pratishthan and her research team comprising Gargi
Podder, Amit Kumar Chakraborty and Priyanka Biswas.
