Preimplantation Genetic Screening
Chromosomal analysis was performed by aCGH (array comparative genomic
hybridization) or NGS (next-generation sequencing). Per iGenomix
procedures and as specified by the manufacturer (Illumina), the 24sure
aCGH platform has an effective 10-Mb resolution; therefore, only full
chromosomal aneuploidies and segmental aneuploidies affecting
chromosomal fragments larger than 10 Mb were
identified30,35. Embryos were vitrified and
transferred in subsequent natural or programmed cycles.
