title: Three CA/GT repeat polymorphisms from loci D21S414 and D21S1234 on human chromosome 21.
abstract: We report three new polymorphic CA repeat microsatellites (ABM-21, ABM-C37A, and ABM-C37B) in two different loci (D21S414 and D21S1234), located in bands q21 and q11.2 of human chromosome 21 (HC21) and that were isolated from a HC21 phage library (LA21NS01). Heterozygosities for ABM-21, ABM-C37A, and ABM-C37B were 0.74, 0.50, and 0.67 respectively. These three CA repeat markers should be useful in the construction of a high resolution genetic map of this region of HC21.
