A high-profile study involving the most widely used PGT[A]Seq method, performed at nine genetic laboratories in four different countries, reported a high incidence of mosaicism (Munne et al., 2019).
Juno’s PGT[A]Seq method is highly validated for the detection of aneuploidy and mosaicism in embryo biopsy specimens. PGT[A]Seq avoids the incorrect classification of potentially viable embryos as “Mosaic” or “abnormal”.
