Use

Establish the parent of origin for syndromes that may result from single-parent inheritance of bot homologues of a specific chromosome pair containing imprinted genetic loci. The best examples of this are Prader-Willi and Angelman syndromes in which maternal and paternal uniparental disomy (for chromosome 15), respctively, are reported. Other examples include Russell-Silver syndrome (chromosome 7) and Beckwith-Wiedemann syndrome (chromosome 11).

Limitations

False-positive or negative results may occur due to factors like blood transfusions, bone marrow transplantation, erroneous representation of family relationships, or contamination of a fetal sample with maternal cells.
