D21S210: A highly polymorphic (GT)n marker closely linked to the β-amyloid protein precursor (APP) gene

摘要

We describe a highly polymorphic (GT)n repeat with 14 alleles that is closely linked to the amyloid precursor protein (APP) gene on human chromosome 21. This marker, D21S210, will be useful for studies of linkage of disorders such as Alzheimer disease to the APP gene.
