title: The relationship of HLA to depression and manic depression. I. The Newfoundland follow-up.
abstract: This report constitutes the Newfoundland component of a large scale replication study to assess the relationship of HLA to affective disorders; the Ontario component will be published subsequently. In a collaborative study between the University of Toronto, Memorial University and the University of Rochester, first degree family members of Probands with major affective disorder in Newfoundland were assessed for the lifetime presence of psychiatric disorder; their blood was also typed for Human Leucocyte Antigens (HLA). Because of the high rate of refusal to participate, only 10 Newfoundland families could be assessed completely. While this number of families is too small to evaluate the role of HLA as a marker of susceptibility to affective disorder, the results will be added to those of the larger Ontario component. Some problems of conducting research in communities similar to those found in Newfoundland are briefly discussed in the context of characteristics of the Probands in the study group as compared with those of subjects who refused entry into the study.
