31.   The researchers suggest the mutant gene reponsible for this premature deterioration may be a key to human aging diseases.

32.   Their powers come from a mutant gene, not the planet Krypton.

33.   These inserted mutant genes disrupt the normal growth-control mechanisms in the cell, causing the cell to escape its built-in restraints on chaotic, cancerous growth.

34.   They add that studies should be undertaken to determine if patients with the mutation should be treated differently from those without the mutant gene.

35.   They are now studying the mutant gene for clues to the nature of the protein it causes to be produced.

36.   Those with a double dose of the mutant gene also fail to produce a protein that helps relay chemical messages between cells.

37.   Until recently, there has been little scientific guidance for women agonizing over whether to have their breasts or ovaries removed because they carry a mutant gene.

38.   A mutant gene in one elephant herdcould easily decimate the entire population of an isolated forest.

39.   Adults who have certain mutant genes are far less likely to develop a form of leukemia than those with normal genes, according to a study released Monday.

40.   Adults who have certain mutant genes are far less likely to develop a form of leukemia than those with normal genes, according to new research published today.
