The N141I mutation in PSEN2: implications for the quintessential case of Alzheimer disease.

ABSTRACT:

Objective

To connect a new family with early-onset Alzheimer disease (EOAD) in Germany to the American Volga German pedigrees.

Design

Pedigree molecular genetic analysis.

Setting

University Medical Centers in Fulda and Giessen, Germany, and in Seattle, Washington.

Results

The families from Fulda, Germany, and the American Volga German families with EOAD share the same N141I PSEN2 mutation on an identical haplotypic background. This establishes that the N141I mutation occurred prior to emigration of the families from the Hesse region to Russia in the 1760s, and documents that relatives of the original immigrant families are presently living in Germany with the mutation and the disease.

Conclusion

A family with the N141I mutation in PSEN2 that presently li
