  1. CHM complete hydatidiform mole, PHM partial hydatidiform mole, NM nonmolar.
  2. aTwo cases with 68,XX (karyotyping and genotyping); three cases with 68,XY (genotyping).
  3. bOne case with 91,XXY (DNA ploidy analysis and genotyping).
  4. cAt least dispermic (genotyping cannot determine more than this [see Bynum et al. 2020, Ref. 33]).
