Researchers are studying large families affected by psoriasis to find out how it is passed from parents to their children and what might trigger the condition.

We studied nuclear families in which at least one member had non-insulin dependent diabetes and in which both parents and their children were available for study.

Researchers studied families with a history of the disease, and found that mutations in the gene were associated with appearance of the syndrome.

Scientists, studying families and twins, have long known that genes help determine weight.

To tease out these differences, researchers must study large families afflicted with cancer.

We are therefore led to study families of Fuchsian systems, and allow the matrices A to depend on the positions of the poles.

The next step would be to study several families with the perfect pitch trait to see if the same gene is at work in them.

We cannot rule out genetic heterogeneity for these genes and suggest studying more families.

Strong evidence of genetic association with increased risk for AA was found by studying families with two or more affected members.
