Array CGH ratio plot depicts ~10. 6 Mb at Xq27. 3- q28. Deletion region is highlighted in red. The deletion resulted in hemizygosity for >100 genes including FMR1 and iduronate 2-sulfatase (IDS). BAC probes (CTD-3109C8 to CTD-2341N11) targeting multiple loci were used. Array was performed using Clarisure CGH by Quest Diagnostics.
