Triploidy, Maternal, nonmolar (triploidy by digyny)

DA: 162

Developmental anomaly information

Definition: Most partial moles have 69 chromosomes (triploidy), including 23 of maternal origin and 46 of paternal origin. Triploidy(digynic triploidy) that involves 23 paternal chromosomes and 46 maternal chromosomes( can result from fertilization of a diploid ovum due to an error at either the first or second meiotic division) is not associated with molar placental changes and, rarely, can result in a live-born infant with multiple birth defects. it is the cause of 20% of spontaneous abortions, premature births and perinatal deaths.


  • 69,XXX triploidy
  • Constitutional triploidy
