A set of ~50 targeted deficiencies created by exploiting hybrid element insertion (HEI) and resolution; designed to fill gaps in deletion coverage.
66F1-66F2;67B2-67B3
The mini-white marker from at least one insertion was retained on the deletion chromosome.
The distal breakpoint fell within the 66F1,2 doublet band, leaving a portion of distal 66F1,2 undeleted.
