Isolation and characterisation of (AC)n microsatellite genetic markers from human chromosome 16.

A cosmid library of human chromosome 16 has been subcloned, and (AC)n microsatellite positive clones have been identified and sequenced. Oligonucleotide primers flanking the repeat were designed and synthesized for (AC)n microsatellites with n greater than 16. These microsatellite loci were then mapped by PCR using a somatic cell hybrid panel of human chromosome 16, and their heterozygosities and allele frequencies determined. Fourteen (AC)n microsatellites were mapped to discrete physical intervals of human chromosome 16 defined by a mouse/human hybrid panel. Nine of these have expected heterozygosities ranging between 0.60 and 0.79, four have expected heterozygosities between 0.02 and 0.49, and one detected three loci where the alleles could not be resolved.
