Triploidy in man: a clearly recognizable syndrome?

E Dudakov, M Perlman, A Ornoy

    Israel Journal of Medical Sciences
    |May 1, 1977
    PubMed
    Summary

    This study describes complete triploidy in a fetus and a liveborn infant. Placental abnormalities in triploidy may cause intrauterine growth restriction and fetal death.

    Area of Science:

    • Genetics
    • Developmental Biology
    • Reproductive Medicine

    Background:

    • Triploidy, a condition where cells have three sets of chromosomes instead of the usual two, is a significant cause of miscarriage and developmental abnormalities.
    • Understanding the genetic and placental factors contributing to triploidy is crucial for reproductive health outcomes.

    Observation:

    • The study details cases of complete triploidy in a 13-week fetus and a full-term infant.
    • One mother had a history of hydatidiform mole, a condition associated with abnormal placental development.

    Findings:

    • Hydatidiform degeneration of the placenta in triploid fetuses and newborns is proposed as a cause for intrauterine growth retardation and fetal demise.
    • While common features exist, a definitive pathognomonic syndrome for triploidy could not be established from the literature review.

    Implications:

    • This research highlights the critical role of placental health in triploidy outcomes.
    • Recognizing suggestive combinations of findings can aid in the diagnosis of triploidy.
    • Further research into the mechanisms of placental degeneration in triploidy is warranted to improve fetal survival and management.
