(1) The study of the faulty gene in Type 1 Diabetes patients leading to finding it as a risk factor to people in the development of the disease.
(2) Tampering the gene content in mouse to study its sexual behavior by its organ in the nose.
(3) Identification of gene that causes the visual disorder, Glaucoma.
These reported gene studies in the dailies are quite interesting. But when will they be put into more practical use for improvement, development and cure?
