11.   But as they get nearer to finding these genes, scientists are beginning to wonder what they have wrought.

12.   But finding disease genes is only a first step, White said.

13.   But it is becoming increasingly clear that going from finding the gene to devising a treatment is a long, rough road.

14.   By looking at many families on two separate continents, researchers can find the genes that contribute to asthma in a relatively large percentage of the population.

15.   Equally problematical are the implications of finding genes like the one for impulsiveness, Silver said.

16.   Eventually, researchers hope they will find the gene that turns those cancers on and off.

17.   Finding the genes and understanding their work in the body will allow scientists to develop medical treatments that attack disease at its root cause.

18.   Finding the gene for a disease is a bit like tracing a glitch in a car to a certain part.

19.   Finding the gene also has implications that extend beyond Stargardt disease.

20.   For example, Hegle recently found a gene that affects the distribution of abdominal fat in men.
