Triploid pregnancy–Clinical implications

Clinical Genetics, 2021
Abstract Triploidy is a life‐limiting genetic aberration resulting from an extra haploid set of chromosomes of paternal (diandric triploidy) or maternal origin (digynic triploidy). Triploidy affects around 1%–2% of all conceptions. The majority of cases is miscarried at early developmental stages. In consequence of genomic imprinting,

The origin of human triploids

Annals of Human Genetics, 1978
Summarythe data using a maximum‐likelihood method was that 66.4 yo of the triploids were the result of dispermy, 23.6 % the result of fertilization of a haploid ovum by a diploid sperm formed by failure of the first meiotic division in the male and 10 % the result of a diploid egg formed by failure of the first maternal meiotic division.

Live-Born Triploid

Archives of Pediatrics & Adolescent Medicine, 1980
Approximately 60% of all human spontaneous abortions during the first trimester of pregnancy are associated with chromosomal aberrations of the conceptus. Nearly 20% of these karyotypes are triploid, 1,2 ie, 66 autosomes and three sex chromosomes. Hence, triploidy is one of the most frequent chromosome aberrations in human abortuses.
