Hemoglobin D-Los Angeles [beta 121(GH4)Glu----Gln] in the Province of Liège, Belgium.

[Huntington's chorea. The Liège experience].

The hereditary choreas are studied in Liège since twenty-five years. The records of psychiatric hospitals (ruled by the belgian law on confinement, 1850-1873), the archives of the "Etat-Civil" (since 1806) and the parochial registers (XVIIIth century) were tapped. From hundreds of choreic records, unquestionable or dubious, genealogical trees, sometimes stretching along nine generations were built up.
