61.   The Tay-Sachs disease gene was identified years ago, Dr. Axelrod said, and people can be tested to see if they have it.

62.   These include therapies to treat cancer, asthma, certain wounds and aging, where certain genes have been identified as playing key roles in these conditions.

63.   This was how CuraGen identified a gene that works on the central nervous system and may play a role in depression or schizophrenia.

64.   Thus far, four genes have been identified, each with multiple mutations that may result in different aberrations of the condition.

65.   Two years ago, with funding from the project, the A-T gene was identified at Tel Aviv University in Israel.

66.   Unlike molecular biology, which can identify single genes, in quantitative genetics scientists use direct observation to examine traits that result from the interactions of many genes.

67.   White shrugs at recent news that researchers have identified a gene that influences fatness, raising hopes that there soon will be a miracle drug to make people thin.

68.   With the help of Kebodeaux and others who have Stargardt disease, a team of researchers from four institutions has identified the gene that causes the disorder.

69.   But now scientists are identifying the genes that control drug reactions and learning how they vary from person to person.

70.   Doctors have identified a gene that can turn off muscle cell growth.
