Abstract

By familial aggregation is meant the occurrence of a disorder at a higher frequency in the relatives of affected individuals than in the general population. This aggregation may be due to genetic, cultural or environmental factors. Assessing whether diseases cluster in families, and searching for the explanation when they do so, are the main questions genetic epidemiologists address.
