Pregnancy Outcome and Postnatal Chromosome Analysis of the Cord Blood and Chorionic Villi in Two Cases after Intrauterine Transfer of Mosaic Aneuploid Blastocysts

Table 1

Summary of Cases 1 and 2.

	Age at egg retrieval; (years)	Age at embryo; transplantation (years)	PGT-A		Amniocentesis	Postnatal chromosomal analysis
			Chromosomal; constitution	Mosaic; percentage (%)		Placenta	Cord blood
Case 1	40	41	Monosomy 5q (aCGH)	40	46,XX (G-banding)	46,XX (SNP array)	46,XX (SNP array)
Case 2	43	44	Monosomy 9q (NGS)	40	Not performed	46,XX (SNP array)	46,XX (SNP array)
			Monosomy 14 (NGS)	40

PGT-A = preimplantation genetic testing for aneuploidy; aCGH = array comparative genomic hybridization; NGS = next-generation sequencing; SNP = single-nucleotide polymorphism.
