40: Mixing ploidies and assays: A case report of perinatal diagnosis and outcome for diploid/triploid mixoploidy

Résumé fourni par la source

Mixoploidy is a rare chromosomal phenomenon that results in concurrent diploid and triploid cell lines within an organism. Mixoploidy can be identified perinatally, arising from either the same zygote (mosaic) or from two different zygotes (chimera). Triploidy can develop as digynic (2 maternal genomes) or diandric (2 paternal genomes) and has been proposed to be a consequence of fusion between a diploid zygote with either a haploid polar body or haploid sperm, among other theoretic mechanisms.
