It is important to denote the proband, so that the relationship to other individuals can be seen and patterns established. In most cases, the proband is the first affected family member who seeks medical attention for a genetic disorder.
Bulaj et al. (2000) examined the usefulness of genetic screening of relatives of probands with hemochromatosis. They studied 291 probands homozygous for mutations in the HFE gene who had presented to a clinic with signs or symptoms of hemochromatosis or who had elevated transferrin-saturation values.
