PCR results from cfDNA and TE biopsy samples. After whole genome amplification (WGA) from both cfDNA and TE biopsy samples, the flanking region of MYO7A was amplified from 15 blastocyst-derived samples. (A) PCR results from cfDNA using Black primers. (B) PCR results from TE biopsy samples with primer set #1. (C) PCR results from TE biopsy samples with primer set #2. Yellow letters indicate PCR amplification failed, ‘*’ indicates an embryo with a cfDNA mutation.
