Scientists at the Indian Institute of Science (IISc) have discovered a new gene that plays a dominant role in causing microcephaly, a brain disorder that leads to tiny brain and life-long reduced mental faculty, particularly in India.
The finding by the IISc scientists may help develop a regular clinical screening tool to detect this severe disorder at the foetal stage itself. Reputed US scientific journal, American Journal of Human Genetics, has reported the discovery of the gene, named STIL, last week.
Four genes were so far known to cause this disease, which is hereditary. The IISc team located a fifth gene, which plays a key role behind this disorder in India.
