## Description

This track shows 255 regions detected as putative copy number polymorphisms by BAC microarray analysis in a population of 55 individuals, 16 of which had previously characterized chromosome abnormalities.

## Methods

Hybridizations were all performed in duplicate incorporating a dye-reversal using proprietary 1 Mb GenomeChip V1.2 Human BAC Arrays consisting of 2,632 BAC clones (Spectral Genomics, Houston, TX). The false positive rate was estimated as ~1 clone per 5,264 tested.
