- *One patient (WD8) had both a 0.7 Mb gain in 10q24 and UPD15
- **The diagnosis of UPD in patient WU5 was considered to be by QC array only
- #Affected siblings in three families with PCNVs that were detected by CMA, affected siblings in three families with PCNVs detected by the QC array, and affected siblings in nine families with SNVs from ES were counted as one family
- ##Does not include cases with autosomal recessive gene deletions or other PCNVs. The SNV detection rate for total ES cases was assumed to be the same as in ES with CMA
- ^Multiple diagnoses consisting both PCNV/UPD and SNV were detected in 37 unrelated ES patients including 19 patients with CMA
