OGM structural variation (SV) algorithm provided the structure and breakpoint information for 17 SVs and revealed six deletions, six tandem direct duplications, one inverted duplication, one paired duplication flanking a cryptic inversion and three balanced chromosomal rearrangements (one likely benign and two with breakpoints disrupting OMIM Morbid gene associated with dominant inheritance disorders). The diagnostic yields of OGM in the cystic hygroma group and multisystem malformation group were both significantly higher than those in other groups (35.7% vs. 10.3%, adjusted
