From: Comprehensive validation of array comparative genomic hybridization platforms: how much is enough?

Determination that the incorrect DNA was spotted on the array for the terminal subtelomeric clone on chromosome 20q. (A) Failure to detect the 20q subtelomere abnormality in sample 59. (B) GS-81-F12 does not deviate in a POC specimen with trisomy 20. (C) POC specimen with trisomy 12 demonstrating duplication of GS-81-F12 on chromosome 20q. POC, products of conception.
