Abstract
In 1995, a surveillance system for prion diseases was set up in the
Basque Country, an autonomous region in northern Spain (2.1 million
inhabitants). In the period from January 1993 to December 2003, we
diagnosed 21 patients with familial prion diseases prospectively and
another 4 patients retrospectively. They represent 35% of all the cases
referred to the epidemiological registry. Two main possible explanations
for this unusual high incidence of familial prion diseases are proposed:
first, comprehensive case ascertainment by public health neurologists;
second, a probable cluster of the D178N mutation within families of
Basque origin related to a still unconfirmed common ancestor. Further
genetic and genealogical studies should resolve this issue.
