1.   A genetic anomaly significantly boosts the risk of heart disease in blacks but not in whites, a new study shows.

2.   Dr. Quing Wang, also of Baylor, is one of the discoverers of the genetic anomaly.

3.   For decades, biologists thought that perfect pitch was a genetic anomaly, passed on from generation to generation.

4.   Happily, they were able to rule out larger genetic anomalies, but of the clubfoot they were certain.

5.   Such homogeneity is greatly prized by researchers, because it means that genetic anomalies can be more easily identified in studies of the origin of diseases.

6.   Why, just that week I had been working on an article about genetic anomalies.
