Genomic DNA samples assayed by array CGH

Dosage per 15q11–q13 interval*
IDClassificationCEN-BP1BP1-BP2BP2-BP3BP3-BP4BP4-TEL
*Intervals are demarcated by the common PWS/AS breakpoints, see fig 1.
†Profile suggests a deletion. However, microsatellite analysis did not include markers in this region.
The dosage (number of copies) of the indicated interval is shown for the 25 individuals studied based on cytogenetic and microsatellite characterisation.
