The combined findings indicate a diandric triploid conception, and the presence of 3 distinct alleles at 1 locus (VWA) in the setting of at least 1 locus establishing diandry (CSF1PO) indicates a dispermic (heterozygous) partial hydatidiform mole.

Hydatidiform Moles Ancillary Techniques to Refine Diagnosis

(5-7) Apart from rare hereditary cases, complete hydatidiform mole (CHM) has a diploid nuclear genome that comprises paternal DNA ("diandry") exclusively; the 2 paternal haploid sets may be derived from duplication of the DNA content of a single sperm or, less commonly, from the DNA of 2 separate sperm.
