Early prenatal diagnosis of triploidy
American Journal of Obstetrics and Gynecology, 1997Our purpose was to investigate the role of ultrasonography and maternal serum human chorionic gonadotropin in the early prenatal diagnosis of triploid pregnancies.A retrospective study on 61,314 consecutive singleton pregnancies examined by ultrasonography at 10 to 14 weeks' gestation was performed to identify the prenatal features of those complicated

In a total sample of 105 triploid spontaneous abortions and live-born and stillborn infants, the parental origin could be determined in 77%. Dispermy was the most common cause of this abnormality. Among the digynic triploids 69% resulted from retention of the second polar body.

Hematological Abnormalities in Triploidy
Archives of Pediatrics & Adolescent Medicine, 1982Triploidy is a common cause of abortion and stillbirth. The incidence in live births is less than 1 in 20,000.1Our investigation of a liveborn infant with 69,XXY karyotype disclosed certain hematological abnormalities that may be unique to this syndrome. The possible diagnostic value of these findings prompts this report.

Cytogenetics, 2008
An analysis of the chromosomes of the rainbow trout, Salmo gairdneri, revealed one triploid individual among 18 specimens examined. The diploid specimens possessed 60 chromosomes, whereas the single triploid possessed approximately 90. Suppression of the second meiotic division followed by fertilization of the unreduced oocyte is the most likely ...

Pathologic Features of the Eye in Triploidy
Journal of Pediatric Ophthalmology & Strabismus, 1981Triploidy is a cytogenetic abnormality characterized by 69 chromosomes rather than the normal 46 in each cell. It is one of the most common chromosomal aberrations reported in early spontaneous abortion. Estimates are that 17-20% of chromosomally abnormal abortuses (early) are triploid.

Triploidy is a lethal chromosomal numeric abnormality, characterized on extra haploid set of chromosomes. Approximately 1-3% of conceptions are triploidy with the majority miscarrying in the 1st trimester. Term infant dies within the first days of life.Triploidy is estimated to occur in 1 of 3,500 pregnancies at 12 weeks’ and 1 in 250,000 at 20 weeks ...

Triploidy syndrome in a liveborn female
Teratology, 1990AbstractWe present the autopsy report of a liveborn triploid female, born after 36 weeks of gestation, who died at the age of 20 hours. External features were diagnostic: fetal hypoplasia, hypertelorism, microstomia, micro and retrognathia, preauricular skin tag, low‐set ears, and 3–4 syndactylia. All internal organs were hypoplastic. There were atrial

This paper contains a review of possible mechanisms leading to triploidy and of cytogenetical and clinical data on about 230 human triploid abortuses and 30 live-born infants. A brief consecutive comparison is made to other species.

Origin of triploidy in spontaneous abortuses
Annals of Human Genetics, 1979SummaryFourteen triploid spontaneous abortuses were studied cytogenetically by sequential Q and C banding and the marker chromosomes were compared with those of the parents. The abortuses comprised all triploid cases in a series of 288 consecutive abortuses of the first 16 weeks of pregnancy occurring in one hospital.
