Paris, France, Oct 15 (AFP/APP): A five-year-old girl with a rare neurodegenerative disease died in the US while taking part in a gene therapy trial run by French biotechnology company Lysogene, the firm said Thursday. The little girl was suffering from Sanfilippo syndrome or mucopolysaccharidosis type III, a rare genetic disease that alters brain development after birth and leads to premature death.
